Metal Injection Molding (MIM)

Material Options

Metal Injection Molding Materials

There are a wide variety of materials available for metal injection molding, and they generally fall into a few 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 - cobalt-chromium, cemented carbides (WC-Co), and cermets (Fe-TiC) 
  • Special materials that include aluminum, precious metals, titanium alloys, nickel, nickel-base superalloys, molybdenum, molybdenum-copper, and particulate composites

MIM materials have modified chemistries from those of casting alloys to withstand the more complex metal injection molding process.  Material compositions that contain extra chromium ease sintering for example. These modifications provide superior material properties so that the final component properties are similar to those produced using other manufacturing methods.

At Dynacast, we specialize in stainless steel, copper and low alloy steel materials for MIM. We can also process Cobalt Chrome (F-75) and other specialty or custom materials. Don’t worry if you don’t see your material of choice. Dynacast can manufacture your precision component using many other metals. Just contact us to discuss it.
