Aluminium and Copper – Which and Why?

They are both metals – yes – but other than that they have many differences, the main ones of which are their weight, cost, appearance and their capacitance which, to the average Joe, is a metals ability to store electrical charge.  Aluminium was, in days gone by, the metal of choice but it seems today that Copper is making a comeback and the designers are switching over!

Copper used in wiring and electrical equipment is nominally pure which is why it is being chosen over Aluminium because Aluminium in its purest form does not seem to be strong enough to cope with many electrical applications.  Different Aluminium alloy properties change depending on the process they are subjected to.  If they are subjected to heat treatment for example, Al6101 becomes harder and stronger.

It has been a rather common misconception that Aluminium has been too soft for some uses and therefore compression connectors must be used to overcome this.  But, with design and plating changes, these compression connectors are no longer necessary.  Alloys and processing can instead be used in order to make Aluminium become just as useful, as good and as strong as Copper…ALMOST!

Copper Coating and Copper Plating

Sounds familiar but this is the opposite way round.  In order to reduce the corrosion of Aluminium and Copper, they are coated in Tin or Silver to reduce their corrosion, because without this Aluminium and Copper are both prone to oxidation and are therefore likely to rust and parts not work appropriately or safely.

All About Copper Plating

Copper Plating is decorative but normally used as it is an extremely functional metal.  It is often used for electricals, road mending techniques, medics and in telecommunications, it really is a multifunctional plating technique.  This is thanks to it being such an excellent conductor, its ability to shield against electro magnetic interference and radio frequency interference, and its excellent levelling properties.  Copper plating is highly thought of in the medical world especially due to the fact that it naturally kills bacteria, thus making it a great protector against infections and diseases, so often also used in laboratory settings, too.

Spring in to Action in Birmingham with Heat Treatment Services

April sees the MACH exhibition at Birmingham’s NEC, where manufacturing in motion will be made visible to anyone wanting to view different techniques and products related to many services, including that of heat treatments, hard coatings and developmental services.

Groups, such as Wallwork Group, are returning again to exhibit here, to celebrate their new expansion project which allows them to offer customers a wider array of heat treatment services, hard coatings and development services.

Heat Treatment

For businesses such as Wallwork Group, exhibitions such as MACH, are important ways of bringing business and contacts together from across the industries.  These can include aerospace, automotive, medical, military and engineering contacts which are the most commonly used industries.  Specialists, skilled labourers, technical engineers and highly knowledgeable scientists combine their expertise to guarantee that you gain the product and information that you require so that you gain the perfect component parts for your business.  They are all at hand to help guide you towards the components which is best for you whilst also, often, making you a great, one-off show day deal, to aid with the financial side of things, too.

NEC, Industry, You and Me

So if you are in the aerospace, automotive, medical, military, engineering, oil and gas or energy/power industries then MACH could very well be the placed for you.  With new creations, the latest of developments and all the manufacturing technologies you could possibly need, there will be over 600 companies exhibiting this year for you to see.  At the last MACH there was 6,500 tonnes of live working machinery on show and two years later, it is set to be even bigger.  If you are interested in attending or finding out more about heat treatments or hard coatings then why not get yourself to Birmingham NEC from the 11th to 15th April – We guarantee it will be worth it if you are in the specified industries.

The Copper Plating Story

We all know plenty about Copper Plating, but what we often don’t know a great deal about is where the process originated from.  I bet you would be interested to learn that it was not at all intentional, but was, in fact, a complete mistake!

Where did Copper Plating come from?

This happy accident occurred centuries ago in 1724, when Thomas Bolsover, a Sheffield cutler, was mending the handle of a silver knife.  He was doing so with the assistance of a copper coin under the pressure vice but got a little distracted and the two metals both became heated.  Due to their heating, they fused together, the silver completely hiding the copper.  This mistake led Bolsover to experiment with other methods of retaining silver and copper together in unity whilst also being one, workable material, and this worked.  This was Bolsovers happy accident, as this was the beginning of the Sheffield Plate.  Dying in 1788, Thomas Bolsover was regarded in his obituary as the first inventor of plated metal, though sadly not the most well known.

All About Copper Plating

Copper Plating is not only undertaken for functional purposes but for decorative purposes, too.  Often used for road mending techniques, medics and in telecommunications, it really is a multifunctional plating technique.  This is due to it being an excellent conductor, has a good ability to shield against electro magnetic interference and radio frequency interference, along with it having excellent levelling properties.  Copper plating is highly thought of in the medical world due to the fact that it naturally kills bacteria, thus making it a great protection against infections and diseases, so often also used in laboratory settings, too.

Everything you need to know about Shot Blasting

Shot blasting is a key factor in the fabrication process.  It is essential so that a clean finish can be provided in order for welding to be undertaken.  It also enables a keyed surface to be produced so that paint can be accepted by the prepared façade.

The Process of Shot Blasting

Shot blasting is undertaken by shot being fired or ‘blasted’ directly at steel, yes, the process is all in the name.  The force of the shot being blasted at the surface of the steel displaces dirt and scale, therefore cleaning the steel and preparing it for the welding process.  This is due to the indentations caused by the shot repeatedly hitting the steel surface, creating a rough texture, which is approximately 70 microns deeps.  Due to this abrasion, it enables paint to stick properly and long term to the steel surface, which creates protection and aids longevity to a component part.

Shot Blasting and Electroless Nickel Plating

The shot blasting preparation is often performed prior to the electroless nickel plating process, but for this to happen the surface preparation must be high quality and thorough, which is why shot blasting is used.  To achieve the ultimate final surface finish, chemical cleaning and activation processes, such as aluminium oxide 180-220 grit are used.  By choosing us to undertake your shot blasting and electroless nickel plating solutions, you know that the standards met will be the highest every time.  At us, the stainless steel shot blasting booth has the capacity to take 216m³.  This minimises the particles which settle on the component parts during their shot blasting or heat treatment processes.

Copper Plating and the Use of Copper Balls

Copper balls have been specially designed to aid the quality of electroplating.  The balls are 25mm, 31mm, 40mm or 50mm in diameter and are made up of 99.9% copper and between 0.04 and 0.06% phosphorus.  They enable the quality of copper plating to be heightened.  This is due to them being able to give free flowing material which dramatically reduces the development of sludge during the process of plating.  This is their sole purpose.  It is also useful that they are able to reduce sludge development because this extends the anode baskets life because the sludge does not erode them.

Successful Copper Plating

The anodes are created using the purest of copper which is oxygen free.  The anodes must be made out of oxygen free copper so that the correct phosphorus content occurs for the electroplating process to be successful.  This process is watched and monitored strictly for quality control and this highly automated process creates a product of great uniformity and high quality of plating.

Why Choose Copper Plating?

Copper plating is functional and decorative.  It is well known for being an excellent conductor.  The deposited layer which is left when copper plating occurs is very bright and levels well.  Copper plating is often used in Medical settings or laboratories due to it being able to kill off bacteria naturally without need for any chemical assistance.  In reference to its decorative flare – this is due to its highly polished copper-pink appearance.  Lacquers can be applied so as to prevent tarnish from building up on the copper plating if it is solely intended for decorative use.

Why Choose Electroplating?

Electroplating is a modern form of metal finishing.  It is commonly used in the automotive, aerospace, medical, army and electrical industries.  It occurs by means of an electrochemical process when metal ions in an electrolyte solution bond to a metal substrate through electrodeposition.   The required metal component is suspended in solution, whereby a direct power supply provides a direct flow of current to the said metal component in the chemical bath.  This current provokes the ions in the solution to attract to the surface of the metallic part, resulting in a metal coating which covers the base metal thoroughly.

Electroplating Benefits

Electroplating is mainly done in order to enhance the performance and longevity of the component part in question.  Certain characteristics can be added to the part in order to create specific needs for the manufacturers.  These can include areas such as:

  • Lower friction through greater lubrication
  • Better wear, abrasion and corrosion resistance
  • Temperature and impact resistance
  • Improved conductivity
  • Improved solderability
  • Porosity reducing
  • Creating added strength and hardness to the component
  • Creating a thicker appearance to smaller or undersized components
  • Increased protection for EMI and RFI shielding

Common Plating

Plating facilities match base metals with a wide array of coating surface metal finishes.  The most commonly used in this field are copper, brass, nickel, steel and bronze.  In order to decide which surface metal is used to coat for the finish, the components uses are highly considered so that the manufacturer can get the highest performance and longest lasting component part electroplated.

As examples:

Gold plating is the perfect solution for electrical conductivity, heat protection and corrosion and can survive in a multitude of environments and temperatures.

Silver plating is commonly used in the electrical industry dues to its low electrical resistance.

Nickel plating is ideal for the chemical industry.  It protects against chemicals and is corrosion and wear resistant.

Copper plating is most commonly used in the automotive industry.

Wheelie Fallen in Love with Copper Plating

It has recently appeared in the news that Ted Baker have teamed up with the famous bicycle producers, Quella.  Together, they are set to create three stylish bespoke models which are predicted to outdo Santander Cycles.  Each of these three new bicycle structures feature copper plating, steel frame, and will have a Brooks England leather saddle.  The bikes will be available in red, green and blue and have been named after fish due to the bikes being inspired by the ability salmon have to swim upstream – Redfinn, Bluetail and Greengill – Well, for the £1,995, you’d expect a pretty name, wouldn’t you!

About Copper Plating

Copper plating is used for both functional and decorative reasons.  Traditionally, it is used for electroforming but can also be used for Electro Magnetic Interference (EMI) and Radio Frequency Interference (RFI) shielding purposes.  The reasons for this are because copper is a brilliant conductor and its deposits from copper plating are very bright.  It also has excellent levelling properties and naturally kills bacteria which is why it is used so frequently in laboratories to plate medical equipment.  The aesthetics of copper plating are used due to its bright, highly polished copper-pink appearance which can be lacquered in order to prevent the copper plating from becoming tarnished if it is intended only for decorative purposes.

Strength, Costs and New Inventions

Swann_Morton_knife_point_medicalA new surgical device has been manufactured which has, at the same time, overcome cost and strength problems.  It has taken around 12 years for developers to get this far after it was discovered that their product did not have the strength for the necessary medical procedures.  So the next 12 years were spent solving this issue of strength within a certain monetary frame, as medics knew that the metal jaws were key to their fine dissection work.  So a hinged jaw has been manufactured to be part of a single-use shear hand piece which is to be used by medics in order for them to perform intricate haemostatic dissection of human tissues in a range of medical areas.

Blades and Nickel – The Medics Choice

These single-use shear hand pieces are used with ultrasonically activated blades and the hinged jaws have now been made out of an often overlooked metal, Hastelloy.  Hastelloy is an alloy with both high nickel and chromium content, which is not only strong but also corrosion resistant, therefore being the medics metal of choice in this area.

Swann Morton and the Medical World

The capabilities of this new medical invention and metal injection moulding process have facilitated new found and close working partnerships between that of leading medical device manufacturers, including that of Swann Morton.  Swann Morton are well known in the medical industry and rely on that of independently owned companies to provide them with complex and often small parts which cannot be manufactured in the traditional ways, often this is due to prohibited costs or design issues, not lack of ability for manufacture.
