Copper Chrome Alloy for Metal Injection Molding

An alloy of copper chromium alloy is formed by adding Cr and other trace alloy elements with Cu substrate.

The alloy at room temperature and 400 ℃ has the following properties:

• High mechanical strength and hardness,

• Good electrical conductivity and thermal conductivity,

  Excellent wear resistance and antifriction performance,

• High temperature oxidation resistance, abrasion resistance and good processability,

• Widely used in high temperature and high strength, high hardness, high conductivity and high thermal conductivity to demand higher parts

●    Physical and mechanical properties

• Density: 8.7g/cm³

• Yield strength: 280 mpa

• Hardness: 70 ~ 100 HV

• Thermal conductivity: 250 w/(m K)

Metal injection moulding of complex shaped parts

MIM technology enables the production of complex shaped parts according to the same manufacturing principle as plastic injection moulding. We inject a mixture of a metallic material with a plastic binder. This is followed by a debinding process in which the plastic is eliminated from the workpiece. Finally, the mechanical properties of the material are restored during sintering.
