EN CC332G (CuAI10Ni3Fe2-C) Aluminum Bronze

CC332G bronze is a bronze formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. CC332G is the EN numeric designation for this material. CuAI10Ni3Fe2-C is the EN chemical designation.

It has a fairly high heat capacity among cast bronzes. In addition, it has a moderately high ductility and a fairly high melting temperature.

The graph bars on the material properties cards below compare CC332G bronze to: cast bronzes (top), all copper alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Alloy Composition

Among cast copper alloys, the composition of CC332G bronze is notable for containing comparatively high amounts of aluminum (Al) and iron (Fe). Aluminum is used to add strength and oxidation resistance, at the cost of requiring additional care during casting. Iron is used to increase strength inexpensively.

Copper (Cu) 80 to 86
Aluminum (Al) 8.5 to 10.5
Nickel (Ni) 1.5 to 4.0
Iron (Fe) 1.0 to 3.0
Manganese (Mn) 0 to 2.0
Zinc (Zn) 0 to 0.5
Silicon (Si) 0 to 0.2
Tin (Sn) 0 to 0.2
Lead (Pb) 0 to 0.1
Magnesium (Mg) 0 to 0.050
