ʻO ka corundum kristal hoʻokahi ka maikaʻi o ka ʻoki ʻana i nā ʻaoʻao he nui, ʻoi aku ka paʻakikī, ka waiwai o ka paʻakikī, ka ikaika wili ikaika, ka wela haʻahaʻa haʻahaʻa, ke ola ʻoki abrasive lōʻihi, a hiki ke hana i ke kila paʻakikī, e like me ke kila kila, ke kila kiʻekiʻe vanadium kiʻekiʻe. etc. He mea kūpono hoʻi ia no ka wili ʻana i nā mea hana deformed a maʻalahi i puhi ʻia a me ka wili hānai nui.
ʻO ka microcrystalline corundum he liʻiliʻi ka nui aniani, ikaika kiʻekiʻe a me ka hoʻomaʻamaʻa ponoʻī maikaʻi, 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 ua kūpono ia no ka ukana kaumaha creep hānai wili me ka hohonu wili nui.
