I-alumina emhlophe exutyiweyokunye ne-alumina emdaka exutywe kakuhle zizinto ezimbini ezisetyenziswa kakhulu. Abantu abaninzi abazi umahluko othe ngqo phakathi kwezi zinto zimbini ngaphandle kombala. Ngoku ndiza kukubonisa ukuba uyaqonda.
Nangona zombini ezi zinto zokuqhobosha zine-alumina, umxholo we-alumina we-alumina emhlophe exutywe kakuhle ungaphezulu kwe-99%, kwaye umxholo we-alumina we-alumina emdaka exutywe kakuhle ungaphezulu kwe-95%.
I-alumina emhlophe exutyiweyoiveliswa ngomgubo we-alumina, ngelixa i-alumina emdaka exutywe ne-brown ine-anthracite kunye ne-iron filings, kunye ne-bauxite ene-calcined. I-alumina emhlophe exutywe ne-white enobunzima obuphezulu isetyenziswa ngabanye abasebenzisi abakumgangatho ophezulu, kuba inamandla okusika angcono kunye nokupholisha okuhle, kwaye isetyenziswa kakhulu kwi-carbon steel, i-alloy steel, i-forged steel, i-hard bronze, njl. Sebenzisa i-alumina emhlophe exutywe ne-white ukuze ucole kakuhle kwaye ukhanye ngakumbi.
I-alumina exutywe ngombala omdaka isetyenziswa kwimarike enkulu, kwaye isetyenziswa kakhulu kwintsimbi ecinyiweyo, intsimbi ekhawulezayo, kunye nentsimbi enekhabhoni ephezulu ukususa ii-burrs kumphezulu, kwaye isiphumo sokusila asikhanyi njengese-alumina emhlophe exutywe ngombala.
