Description:

CoCrMo is a cobalt-based solid solution strengthened alloy with excellent strength, ductility and high temperature oxidation ability. It is a non-magnetic cobalt-chromium-molybdenum alloy that can be used to manufacture functional components in the biomedical, aerospace, and high-performance engineering sectors.

 

Application field：

lPowder can be used in laser/electron beam additive manufacturing (SLM/EBM), powder metallurgy (PM), spraying, welding and other processes.

lPowder is mostly used for 3D printing of biomedical materials such as teeth, human body supports, artificial joints and so on.It is biocompatible and has superior Mechanical and thermal properties include: high elasticity In addition, modulus, tensile strength and temperature resistance With excellent wear resistance and corrosion resistance.-Recommended mesh size: 63 µm
