Zogwiritsidwa ntchito zaMetal jakisoni akamaumba:
Ndondomeko ya MIM ikugwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo zitsulo zotsika, zitsulo zosapanga dzimbiri, zitsulo zachitsulo, faifi tambala aloyi, tungsten aloyi, aloyi olimba, titaniyamu aloyi, maginito zipangizo, Kovar aloyi, ziwiya zadothi zabwino, etc.
Ndizinthu zotani zazitsulo zomwe zili zoyeneraChithunzi cha MIM:
1. Kulemera kwa zigawo za MIM nthawi zambiri kumakhala 0.2g - 200g.
2. Malo omwe akuyembekezeredwa ndi 100 square centimeters.
3. Kukula kwa magawo a MIM kupitirira 10MM ndi ± 0.5%.
4. The MIM mbali pazipita khoma makulidwe ndi 10MM.
5. Kukula kochepa 0.2MM.

| Heavy alloy | W-Ni-Fe,W-Ni-Cu,W-Cu | Makampani a usilikali, mauthenga, zofunikira za tsiku ndi tsiku |
| Titaniyamu alloy | Ti, Ti-6Al-4V | Zida zamankhwala ndi zida zankhondo |
| Zida zamaginito | Fe, NdFeB, SmCo5, Fe-Si | Mitundu yosiyanasiyana ya maginito |
| Chida chitsulo | CrMo4, M2 | Zida zosiyanasiyana |
Table 2 Katundu wa zinthu zomwe zimagwiritsidwa ntchito kwambiri ndi MIM:
| Kusankhidwa Kwazinthu | Kupanga kwa Aloyi (wt%) |
Mkhalidwe | Kuchulukana p (g/cm³) | Mtengo wa UTS σ b(Mpa) | YS σ 0.2 (Mpa) | Elongation σ (%) |
