EN CC333G (CuAI10Fe5Ni5-C) Nickel-Aluminum Bronze
CC333G bronze is a bronze formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. CC333G is the EN numeric designation for this material. CuAI10Fe5Ni5-C is the EN chemical designation.
It has a fairly high heat capacity among cast bronzes. In addition, it has a very high tensile strength and a fairly high melting temperature.
The graph bars on the material properties cards below compare CC333G 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 CC333G bronze is notable for including chromium (Cr) and bismuth (Bi). Chromium additions permits certain types of heat treatment to improve mechanical strength. Bismuth improves machinability and pressure tightness. It is used a non-toxic but more expensive replacement for lead.
