What are the key properties of copper-based alloys?

Copper-based alloys provide a range of benefits for use in industrial settings thanks to their versatility.

Alloys made from copper are often malleable and ductile with high strength, conductivity, corrosion resistance and machinability. Some copper alloys are also used as conductors in a variety of applications.

Where are copper alloys used? 

Because copper-based metal alloys have good corrosion resistance, the materials are commonly used in subsea applications which are seawater-facing. The resistance to corrosion can help to prolong the lifespan of components, minimising associated costs of repair.

The electrical conductivity of many copper-based alloys makes them particularly attractive when designing wiring. The high heat conductivity makes them perfect material for boilers to transfer heat as efficiently as possible.

Custom copper alloys have good machinability properties, adding to the versatile nature of the material. This means that the production lead times of a component are minimised because material removal rates are maximised.

Pairing copper with different metals

Copper-Zinc alloys

Alloys of copper and zinc are extremely high-strength materials with the ability to withstand consistent wear and tear. This means that copper-zinc is frequently used in structural applications.

Copper-zinc alloys are also resistant to corrosion, as well as wear and tear, which makes them attractive in subsea design engineering.

Copper-Aluminium alloys

Similar to copper-zinc alloys, alloys featuring both copper and aluminium offer both high strength levels and resistance to both corrosion and wear.

The low corrosion levels of copper-aluminium alloys lead them to be commonly used in aircraft construction where a multitude of metallurgical properties are paired with low weights.

Copper-Nickel alloys

Copper-nickel alloys show a high resistance to both biofouling and corrosion. Alongside the material benefits of copper-nickel alloys, they also show antimicrobial properties.

Copper-nickel alloys are used in a variety of high-stress environments like seawater cooling systems, shipbuilding and in submarines.
