Copper Alloys, Aluminium BronzeCW307G (CA104) Bar

A wrought high strength aluminium bronze alloy offering excellent wear and corrosion resistance.

Copper aluminium alloys are commonly known as aluminium bronzes. These alloys are a range of copper-based alloys in which the primary alloying element is up to 14% aluminium.

CW307G is one of the most popular complex nickel aluminium bronzes. It offers high strength, hardness, and an excellent resistance to wear, shock and abrasion. The addition of nickel increases the alloys strength without diminishing its excellent ductility, toughness and corrosion resistance.

It is an excellent choice for applications involving heavy loads, abrasive wear resistant, friction, abrasive wear and corrosion. The alloy is widely used in aerospace, marine, power, automotive & industrial applications.
