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.
