Hale Hana Nichrome Alloy Strip oNi80Cr20Ni70Cr30 Ni60Cr15 Ni35Cr20 i hoʻohana ʻia i nā lako hale
ʻO Ni70Cr30 kahi austenitic nickel-chromium alloy kūpono no nā noi wela a hiki i 1250 ° C. ʻO ka maʻiʻo chromium kiʻekiʻe (30% i ka awelika) hāʻawi i ka manawa ola maikaʻi loa, ʻoi aku hoʻi i nā noi umu. Hōʻike ʻia ʻo Ni70Cr30 e ka resistivity kiʻekiʻe, ke kūpaʻa oxidation maikaʻi, ka ductility maikaʻi ma hope o ka hoʻohana ʻana a me ka weldability maikaʻi loa.
Hoʻohana ʻia ʻo Ni70Cr30 no nā mea hoʻomehana uila i nā umu ahi. ʻO nā noi maʻamau: nā umu uila a me nā enamelling, nā mea wela mālama, nā kapuahi a me nā kiln me kahi ea hoʻololi.
