General Characteristics of the Superfine 7μm MIM Powder

Typical powder PSD

  

  Basic characteristics

• The finest industrialized powders applied in MIM industry
• With high fluidity
• Easy to be sintered with very high density and low deformation
• Shiny appearance with low surface roughness
• Typical materials:

               Stainless steels: 316L、304L、17-4PH……

               Low alloy steels: 8620、4140、8740、4605……

               Carbon steels: HK30、420、440、SKD11……

                Cobalt based alloys: 8620、4140、8740、4605……
