Hana ʻia ka corundum keʻokeʻo mai ka pauka alumini oxide a hoʻoheheʻe ʻia i ka wela kiʻekiʻe, e hōʻike ana i ke kala keʻokeʻo. ʻOi aku ke kiʻekiʻe o ka paʻakikī ma mua o ka corundum brown, a ʻoi aku ka haʻahaʻa o ka ʻoʻoleʻa. ʻO ka corundum keʻokeʻo i hana ʻia e kā mākou hui he mau hiʻohiʻona o ka maikaʻi o ka huahana paʻa, ka hui ʻana o ka nui o nā ʻāpana like, haʻahaʻa haʻahaʻa magnetic, kiʻekiʻe puʻupuʻu nui, kiʻekiʻe paʻakikī, paʻakikī maikaʻi, a me ka maʻemaʻe kiʻekiʻe. Hoʻokuʻu ʻia kāna mau huahana ma mua o 20 mau ʻāina a me nā ʻāina e like me ʻEulopa, ʻAmelika Hui Pū ʻIa, a me Asia Hikina Hema.
ʻO nā mea hana abrasive i hanaʻia me ia, he kūpono ia no ka wiliʻana i ke kila kalapona kiʻekiʻe, ke kila kiʻekiʻe, ke kila paʻakikī, a me nā mea'ē aʻe.
Ma ke ʻano he abrasive uhi, ʻo ka corundum keʻokeʻo kahi mea me ka ʻili ikaika a me ka wili. Ma muli o kāna mau hopena ʻoi a me ka angular particle, ʻaʻohe blockage i ka wā wili, a kūpono ia no ka hoʻoliʻiliʻi ʻana i nā mea palupalu like ʻole (lāʻau, plastic), a me nā mea ʻē aʻe.
