Hana ʻia ka uea hoʻopaʻapaʻa i ka Nichrome alloys, e like me Ni80Cr20, Ni60Cr15, a me nā mea ʻē aʻe.
He nui nā pōmaikaʻi o ka uea hoʻoheheʻe kūʻē kūʻē, e like me ka hiki ke deformation, ke kūpaʻa wela, ke ʻano mechanical, ka hiki ke shockproof i ke kūlana wela a me ka anti-oxidization. Hoʻokumu ʻo Nichrome Wire i kahi papa pale o ka chromium oxide ke hoʻomehana ʻia no ka manawa mua. ʻAʻole e oxidize nā mea ma lalo o ka papa, e pale ana i ka uea mai haki a ʻā paha. Ma muli o ke kūlana kiʻekiʻe o ka Nichrome Wire a me ke kū'ē i ka oxidation i nā wela kiʻekiʻe, ua hoʻohana nui ʻia ia i nā mea hoʻomehana, hoʻomehana umu uila a me nā kaʻina hana wela i ka ʻoihana kemika, mechanical, metallurgical a me nā ʻoihana pale.
