The most commonly used elements in MIM processing are:

  • Iron
  • Nickel
  • Chromium
  • Molybdenum

Iron and nickel are two of the easiest elements to process because of their compatible melt temperature and ease of sintering. Iron and nickel make up a significant amount of the total tonnage produced in the industry.



  • A-286 – Excellent corrosion resistance, high temperature strength
  • Hastelloy X – Good oxidation resistance, high temperature strength
  • Inconel 625 – Excellent corrosion and heat-resisting characteristics

Stainless Steels

  • 17-4PH – Best combination of strength and corrosion resistance
  • 316 – Excellent corrosion resistance
  • 420 – High hardness

Low Alloy Steels

  • 2200 – Similar to PM FN-0200, good magnetic and toughness properties
  • 4605 – High treatable, high-strength steel, up to HRC 52
  • 4140 – Heat treatable, high-strength steel, up to HRC 60

Controlled Expansion Alloys

  • Fe-Ni – The alloy composition (ie, Invar, Alloy 42, etc) can be tailored for the application’s thermal expansion requirement
  • F15 – AKA Kovar®, the alloy is engineered for hermetic glass-metal seals

High Density Alloys

  • W-based – High temperature sintering proficiency allows various tungsten-nickel-iron alloy capability; sintered densities range up to 18 g/cc

Soft Magnetic Alloys

  • Fe-Si – Silicon content up to 9% allows for high resistivity with good soft magnetic response
  • Fe-Co – Excellent magnet saturation properties
