MIM Metals

MIM materials have had their chemistries modified in order to withstand the complex metal injection molding process.

There are a wide variety of materials available for metal injection molding, and they generally fall into four categories:

  • Ferrous alloys—steels, stainless steels, tool steels, iron-nickel magnetic alloys, and specialty ferrous alloys such as Invar and Kovar 
  • Tungsten alloys—tungsten heavy alloys and tungsten-copper
  • Hard materials—cemented carbides (WC-Co), and cermets (Fe-TiC)
  • Special materials that include, precious metals, titanium alloys, cobalt-chromium, nickel, nickel-base super alloys, molybdenum, molybdenum-copper, and particulate composites

At Orange Koi, we specialize in stainless steel, copper and low alloy steel materials for MIM. We can also process Cobalt-Chromium (F-75) and other specialty or custom materials. 

Don’t worry if you don’t see your material of choice, we can manufacture your precision component using many other materials.

  • Stainless Steel

    Ideal for applications requiring strength, ductility, and corrosion resistance.

    We work with Austenitic 340L, 316L; Martensitic 420,440 A/B/C; Ferritic 430

  • Low Alloy Steel

    Generally used for structural applications especially when high strength and hardness are necessary

    We work with Low C, case hardening 4600 (Fe - Ni - Mo);
    Med C, through hardening 4630 - 4650 (Fe - Ni - Mo - Cr);
    High C, through hardening 52100

  • Additional MIM Materials

    These MIM materials are manufactured from pre-alloyed powder or mixtures of iron and other elements like nickel, chromium, cobalt, and silicon.

    We work with Magnetic Fe-Si, Fe50Co, Fe50Ni
    Electronic Packaging Kovar, Fe-Ni (Invar)
    High Temperature Co-Cr (F-75), Inconel, Hastelloy, HK-30, 310Nb, Tribloy
