Nickel chromium restastance alloy resistohm 40 resisstance ribbon gests
Ni40C20he austetitic niytentic-chromium alloy Hōʻikeʻia ka alloy e ka resistivity kiʻekiʻe a me ka pale o ka oxidation maikaʻi. He maikaʻi maikaʻi ia ma hope o ka hoʻohanaʻana a me ka wā maikaʻiʻole.
Nā noi maʻamau no ka ni40cr20 i nā mea wela e mālama ai, nā mea wela e hoʻokūkū ai, kaumaha nui. Hoʻohanaʻia kaʻAmelika no nā kīʻaha kīʻaha a me nā mea wela wela ma nā kīʻaha puaʻa, nā wahi koho lole.
