Metal Injection Molding Materials

MIM MATERIALS

According to the different metal materials in MIM materials, we divide the materials used for metal injection molding into the following 4 categories:

1.Iron-based alloys, including steel, stainless steel, iron-nickel alloys, and iron-nickel magnetic alloys

2 .Carbide, such as tungsten copper alloy and tungsten heavy alloy

3.Ceramic material (Fe-TiC) and cemented carbide (WC-Co)

4.Other special materials: precious metal alloys, titanium alloys and nickel-based super alloys,

JH MIM is committed to providing our customers with MIM iron-based, stainless steel, titanium alloy and cermet materials.

MPIF Standard 35 for Metal Injection Molded Parts currently covers the above range of low alloy steels, stainless steels and soft magnetic alloy grades
