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 aluminum, precious metals, titanium alloys, cobalt-chromium, nickel, nickel-base super alloys, molybdenum, molybdenum-copper, and particulate composites

At AMTMIM, 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.

  • Low Alloy Steel

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

  • 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.

  • Metal Properties

    Use our dynamic metal selector tool to review alloy mechanical properties and filter to choose the right material for your project.
