Copper Alloys

Copper Alloys

B&B coatings can combine different materials in order for us to create a completely bespoke solution for your application. 

 

Many engineers will be familiar with Copper through electro-plating. Electro-plated Copper is most often used as a way to create a smooth uniform undercoat for other processes such as Silver Plating. It is thin and malleable in nature and enhances a component with improved electrical and heat conductivity.

 

The main difference between this and HVOF applied Copper Alloys is that HVOF is an additive process and as such can be built up into a thick coating as well as used to repair worn areas. There are a number of different Copper Alloy based coatings depending on your application.

 

Copper Coating

 

Pure Copper Coatings applied through HVOF have similar properties to electro-plated Copper. They provide excellent electrical and thermal conductivity as well as being non-magnetic. HVOF coatings are hard and dense in nature with a low porosity. This coating is often used for EMI Shielding.

 

Copper Aluminium Alloys

 

Copper-Aluminium Alloys are most often used in repair of worn areas in components made of Copper. They provide enhanced wear and fretting resistance as well as added protection to oxidation when sealed. Typically these coatings are used on pumps as a form of cavitation control, as well as being used on Piston Guides, Shifter Forks and Compressor.

 

Copper Nickel Alloys

 

Copper-Nickel Alloys are particularly dense in nature and resistant to galling and fretting. These coatings have improved lubricity and are often used in Jet Engine Turbine blade Roots and Disk Slots.
