ʻO ka corundum kristal hoʻokahi ka maikaʻi o ka ʻoki ʻoki ʻana i nā ʻaoʻao he nui, kiʻekiʻe paʻakikī, kiʻekiʻe o ka paʻakikī waiwai, ikaika wili ikaika, haʻahaʻa wili wela, lōʻihi abrasive ʻoki ola, a hiki ke hana i ke kila paʻakikī a paʻakikī, e like me ke kila kila, ke kila kiʻekiʻe vanadium kiʻekiʻe, a me nā mea ʻē aʻe.
ʻO ka microcrystalline corundum he liʻiliʻi liʻiliʻi ke aniani, ikaika kiʻekiʻe a me ka hoʻomaʻamaʻa ponoʻī, hiki ke hoʻohana ʻia no ka wili hohonu. I ke kaʻina o ka wili ʻana, hōʻike ka microcrystalline corundum abrasive i kahi micro-breaking state a loaʻa iā ia ka waiwai ponoʻī ponoʻī, no laila kūpono ia no ka ukana kaumaha creep hānai wili me ka hohonu wili nui.
