CuNi2SiCr

Product catalog summary

Mechanical Properties:
Densities and mechanical properties such as traction resistance, elasticity, lengthening, hardness, and thermal conductivity are specified for copper alloys used in pistons. For example, the density is 8.71 g/cm3, with a minimum traction resistance of 590 N/mm2 and a hardness range of 170-210 HB.

Copper Alloy for Pistons:
This section describes the copper-nickel-silicon-chrome alloy (CuNi2SiCr) used for resistance welding electrodes and pistons in aluminum injection machines. The chemical composition includes 1.8-3.0% Ni, 0.4-1.0% Si, and 0.2-0.8% Cr.

Cobalt Nickel Beryllium Copper:
The CuCoNiBe alloy is detailed with applications in resistance welding electrodes, aluminum die-casting, and electrical components. The chemical composition includes 0.8-1.3% Ni, 0.4-0.7% Be, and 0.8-1.3% Co. Mechanical properties include a density of 8.8 g/cm3 and a minimum traction resistance of 650 N/mm2 for extruded forms.

Applications:
Various applications for the copper alloys are listed, including resistance welding electrodes, pistons for aluminum injection, and components for electrical and die-casting uses.
