EN CC334G (CuAI11Fe6Ni6-C) Aluminum Bronze
CC334G bronze is a bronze formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. CC334G is the EN numeric designation for this material. CuAI11Fe6Ni6-C is the EN chemical designation.
It has a very high heat capacity among cast bronzes. In addition, it has a very high tensile strength and a fairly low ductility.
The graph bars on the material properties cards below compare CC334G 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 CC334G bronze is notable for containing comparatively high amounts of iron (Fe) and aluminum (Al). Iron is used to increase strength inexpensively. Aluminum is used to add strength and oxidation resistance, at the cost of requiring additional care during casting.
