Nimonic
High Temperature Alloy
◆ Nimonic90 ili ndi mphamvu zolimba kwambiri komanso kukana kukwawa, kukana kwa okosijeni wabwino komanso kukana kwa dzimbiri, ndipo ndiyoyenera ma turbine discs, masamba ndi zomangira zotentha kwambiri zama injini za turbine.
◆ Nimonic91 ili ndi mphamvu zambiri komanso anti-oxidation pa kutentha kwakukulu kwa 650-1000 ° C, ndipo ndi yoyenera pazigawo zotentha kwambiri monga ma aero-injini, injini za rocket, ndi mphamvu za nyukiliya.
