Metal injection molding, or MIM, is a relatively new subset of powdered metallurgy where metals are atomized to a very fine powder, mixed with a binder, molded in a similar fashion to polymers, then de-bound and sintered to full density.

As such, close to the entire industry of powdered metallurgic materials can be MIM-ed net or near-net shape with extremely high material utilization (<98%), precision, and repeatability. Examples of metals PTI regularly MIM’s:

Low Alloy Steels:

  • 4140, 4340, 4605, 100Cr6, 8620

Stainless Steels:

  • 17-4 PH, 316L, 440, 420, 410

Nickel Based Super Alloys:

  • Hastelloy X, Inconel, Waspaloy

Refractory & Specialty Metals:

  • Tungsten, Titanium, Tantalum
