When an application demands high strength and high hardness and simultaneously requires a material with good thermal and electrical conductivity PIAD's copper nickel-silicon alloys C030 and C031 come into play.
These copper-nickel alloys contain small amounts of Nickel and Silicon in specific ratios to form Ni2Si which allows these materials to be heat treatable similar to Chromium Copper.
Copper-nickel-silicon alloys have a propensity for hot tearing and should only be used if the geometry of the parts is not complex.
Below are the typical properties of copper-nickel-silicon alloy - C031 after heat treating.

|
||
Elongation | 3-4% minimum | |
|
||
Hardness | 190-204 HB minimum | |
