Within the market taxonomy of Metal Injection Molding Materials, material types are classified by base alloy chemistry and functional performance. Stainless‑steel feedstocks, led by 316L and 17‑4PH grades, dominate with an estimated 40 % of total volume due to their corrosion resistance and weldability across automotive and medical applications. Tool‑steel powders, such as high‑speed steel (HSS) and powder‑metallurgy (PM) tool steels, represent roughly 20 % and are essential for high‑stress industrial components requiring superior hardness. Copper‑alloy materials, including Cu‑Cr‑Zr and Cu‑Sn, account for about 12 % and are primarily deployed in thermal‑management parts for electronics and power‑train modules. Nickel‑based superalloys, exemplified by Inconel 718 and Monel, hold a 15 % share, driven by aerospace and high‑temperature industrial uses. Titanium‑alloy feedstocks, notably Ti‑6Al‑4V, comprise roughly 8 % of the market, reflecting niche adoption in lightweight aerospace and biomedical implants. The remaining 5 % consists of specialty alloys such as cobalt‑chromium and high‑entropy powders, which address highly specific performance criteria.
