Description
CW307G Round Bars / CA104 Round Bars – Aluminum Bronze
CW307G / CA104 Round Bars 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.
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.
The CA104 / CW307G type material is a wrought high strength aluminium bronze alloy offering an excellent wear and corrosion resistance. It is one of the most popular grades of aluminium bronze with additions of 10% Aluminium, 5% Nickel and 5% iron to enhance the overall properties of the alloy.
Mainly utilised for its high strength levels and an excellent resistance to erosion and corrosion in seawater and many other aggressive and chloride containing environments. As with many other aluminium bronzes the CA104 / CW307G material offers a very good wear and abrasion resistance, an ability to withstand shock loading and the retention of properties at cryogenic temperatures.
