Loaʻa ka alumina keʻokeʻo i hoʻopili ʻia i nā ʻano like ʻole, me nā grits, ke one, a me ka pauka, a hoʻohana ʻia i nā ʻano hana like ʻole:
- Wili a me ka hoʻowali ʻana: nā huila abrasive, nā kāʻei, a me nā diski no ka wili pololei ʻana i nā metala, nā keramika, a me nā mea i hui pū ʻia.
- Ka Hoʻomākaukau ʻana i ka ʻIli: nā hale hana hao, ka hana ʻana i ka metala, a me ke kūkulu moku
- Nā mea pale ahi: nā piliki ahi, nā mea hoʻoheheʻe pale ʻino, a me nā huahana pale ʻino ʻē aʻe i hoʻohālikelike ʻia a i ʻole i hoʻohālikelike ʻole ʻia
- Ke Kiola Pololei ʻana: nā ʻōmole hoʻolei hoʻopukapuka kālā a i ʻole nā kikowaena, e hopena ana i ka pololei kiʻekiʻe, nā ʻili laumania, a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ke kiola ʻana.
- ʻO ka hoʻopāhū ʻana o ka ʻili: ka hoʻomaʻemaʻe ʻana i ka ʻili, ke kālai ʻana, a me ka hoʻomākaukau ʻana i nā ʻoihana e like me ka hana metala, nā kaʻa, a me ka aerospace, wehe i ka ʻōpala, ka pena, ka unahi, a me nā mea haumia ʻē aʻe mai nā ʻili me ka ʻole o ka hōʻino ʻana.
- Nā Superabrasives: nā mea hana abrasive i hoʻopaʻa ʻia a i ʻole i uhi ʻia, nā kila wikiwiki, nā kila mea hana, a me nā keramika
- Nā Keramika a me nā Tile
