Aluminum Bronze

The addition of aluminum increases strength and hardness of bronze. Aluminum bronze also excels in resistance to temperature changes and corrosion, even in saline water. It has good weldability, high tensile strength, yield strength and malleability. It is used in production of worms and worm gears, gears, bearings, bushings or valve components. The most common aluminum bronze alloys have about 10% of aluminum.

We supply bronze in the form of bars (round, flat, square, hexagonal, hollow), tubes, or sheets.

Below you will find a selection of the most common material grades we work with. Notice for the EN 1982 standard: We usually use the prefix CC (e.g., CC492K), which denotes castings, but you may encounter the prefix CB (e.g., CB492K) elsewhere, indicating ingots. The prefix CW denotes wrought alloys.

If you are interested in another grade or alloy, do not hesitate to contact us.

CuAl10Fe4Ni4

CuAl10Fe4Ni4 is an older Czech designation for CuAl10Ni5Fe4 (CW307G). It is one of the most popular aluminum bronzes. This material has high strength (even at temperatures around 400°C), resistance to erosion, cavitation, abrasion, corrosion (even in seawater) and good fatigue life. However, the machinability is quite poor. Sliding properties are good if enough lubrication is provided. It is used in components exposed to high mechanical or chemical stress such as bearing bushes and pressure nuts, as well as on steam fittings, slip rings, cog and worm gears, mechanical joints, bushings, condenser plates and heat exchangers, etc. CuAl10Ni5Fe4 is similar to CuAl10Fe5Ni5.
