I loko o ka metallurgy a me ka ʻoihana foundry, ʻo nā metala non-ferrous nā metala a i ʻole nā mea hao ʻaʻole i loko o ka hao (ferrite) i ka nui o ka nui. Ke hoʻohālikelike ʻia me nā metala ferrous, loaʻa nā metala non-ferrous i nā pono he nui o ke kaumaha haʻahaʻa (egaluminika), kiʻekiʻe conductivity (egkeleawe), waiwai non-magnetic a kū'ē paha i ka corrosion (egzinc). ʻO nā metala non-ferrous i hoʻohana nui ʻia no ka hoʻoheheʻe ʻana, ʻo ia ka aluminika, keleawe, nickel, chrome, molybdenum, manganese, magnesium a me ka zinc, a me nā alloys e like me ke keleawe. Hoʻomaʻemaʻe pinepine ʻia nā metala non-ferrous ma o ka electrolysis. Hoʻohui ʻia ka nui o nā metala non-ferrous i loko o ka hao ma mua o ka hoʻolei ʻana e kiʻi i ke kila kila a i ʻole ka hao hoʻoheheʻe kūikawā i loaʻa kekahi mau hana i makemake ʻia e like me ke kūpaʻa ʻana, ka pale ʻana i ka corrosion, ka pale wela ... etc.
