Ni70Cr30waa nikkel-chromium alloy (NiCr alloy) oo lagu garto iska caabin sare, caabbinta oksaydhka wanaagsan iyo xasilloonida qaab aad u wanaagsan. Waxay ku habboon tahay in lagu isticmaalo heerkul ilaa 1250 ° C, waxayna haysaa nolol adeeg heer sare ah marka la barbar dhigo birta chromium aluminium aluminium.
Codsiyada caadiga ah eeNi70Cr30waa walxaha kuleyliyaha korontada ee qalabka guriga, foornooyinka warshadaha iyo iska caabiyeyaasha (iska caabinta fiilada, biraha filimka birta ah), birta fidsan, makiinadaha feeraha, kuleyliyaha biyaha, caagagga dhinta, biraha alxanka, walxaha tuubada galka leh iyo walxaha kartoonada.
