UNS C95410 Aluminum Bronze
C95410 bronze is a bronze formulated for casting. It has a fairly high heat capacity among cast bronzes. In addition, it can have a fairly high tensile strength and has a very high melting temperature.
The properties of C95410 bronze include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare C95410 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 C95410 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.
