0.12mm 80/20 Nichrome Uea no na kapuahi hana
ʻO nā alloys Nickel Chrome (NiCr) he mau mea kūʻē kiʻekiʻe i hoʻohana pinepine ʻia i nā noi me nā mahana hana kiʻekiʻe loa a hiki i 1,250°C (2,280°F).
ʻIke ʻia kēia mau ʻāpana Austenitic no ko lākou ikaika mechanical kiʻekiʻe ma nā mahana i hoʻohālikelike ʻia me nā alloys FeCrAl a me ko lākou ikaika kolo kiʻekiʻe. ʻOi aku ka ductile o nā alloys Nickel Chrome ke hoʻohālikelike ʻia me nā alloys FeCrAl ma hope o nā manawa lōʻihi i ka mahana. Hoʻokumu ʻia kahi Chromium Oxide ʻeleʻele (Cr2O3) i nā wela kiʻekiʻe i hiki ke hoʻopaʻa ʻia, a i ʻole ka ʻili ʻana, e hoʻopōʻino ʻia ma muli o ka noi. ʻAʻole loaʻa i kēia oxide nā mea hoʻoheheʻe uila e like me ka Aluminum Oxide (Al2O3) o nā alloys FeCrA. Hōʻike ka Nickel Chrome alloys i ka pale ʻino maikaʻi me ka ʻokoʻa i nā kaiapuni kahi i loaʻa ai ka sulfur.
