I-alumina ceramiciwuhlobo lwempahla ye-ceramic ikakhulukazi eyakhiwe nge-aluminium oxide (AI2O3), esetshenziswa njengento evikelayo ezingxenyeni zikagesi.I-alumina ceramicine-conductivity enhle, amandla emishini, nokumelana nezinga lokushisa eliphezulu. Izici zayo ziyenza ibe enye yezinto zobumba ezisetshenziswa kakhulu ezakhiweni, ezigugileyo, nasezindaweni ezigqwalile.
1. Ukuqina okuphezulu
Ukuqina kwe-Rockwell yi-HRA80-90, ubulukhuni buphansi kunedayimane, bungaphezulu kakhulu kokumelana nokugqokwa kwensimbi engagqoki nensimbi engagqwali.
2. Ukumelana nokugqoka okuhle kakhulu
Ikalwa izikhungo zocwaningo ezingochwepheshe, ukumelana kwayo nokugqokwa kulingana nezikhathi ezingama-266 zensimbi ye-manganese. I-Gaoming cast iron izikhathi ezingu-171.5, ngokweminyaka yethu engaphezu kweshumi yocwaningo lokulandela umkhondo wamakhasimende, ngaphansi kwezimo ezifanayo zokusebenza, inganweba impilo yesevisi yemishini okungenani izikhathi eziyishumi ngaphezulu.
3. Isisindo esincane
Ukuminyana kwayo kwe-3.5g/cm3 kuyingxenye kuphela yensimbi, enganciphisa kakhulu umthwalo wemishini.
