I-alumina ceramicluhlobo lwemathiriyeli ye-ceramic ikakhulu eyenziwe nge-aluminiyam oxide (AI2O3), esetyenziswa njengento yokugquma kumacandelo ombane.I-alumina ceramicinokuqhuba kakuhle, amandla omatshini, kunye nokumelana nobushushu obuphezulu. Iimpawu zayo zenza ukuba ibe yenye yezona zinto zisetyenziswa kakhulu kwi-ceramics kulwakhiwo, ukunxitywa, kunye neendawo ezinobungozi.
1. Ubunzima obuphezulu
Ukuqina kwe-Rockwell yi-HRA80-90, ubunzima bungaphantsi kunedayimani, bungaphezulu kakhulu kunokumelana nokunxitywa kwentsimbi enganyangekiyo kunye nentsimbi engenasici.
2. Ukumelana nokunxiba okugqwesileyo
Ilinganiswe ngamaziko ophando oluchwephesha, ukumelana kwayo nokunxiba kufana namaxesha angama-266 entsimbi ye-manganese. I-Gaoming cast iron 171.5 amaxesha, ngokweminyaka yethu engaphezu kweshumi yophando lokulandela umkhondo wabathengi, phantsi kweemeko ezifanayo zokusebenza, inokwandisa ubomi benkonzo yezixhobo ubuncinane amaxesha alishumi ngaphezulu.
3. Ubunzima obulula
Ubuninzi bayo be-3.5g / cm3 kuphela isiqingatha sentsimbi, enokunciphisa kakhulu umthwalo wezixhobo.
