Iiseramikhi zealumina
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 lokulandelela abathengi, 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.
