Brown Alwminiwm Ocsid
Disgrifiad byr:
FEATURES Brown aluminium oxide is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials. Grit size :12#-220#; Micropowder: 240#-1200#. Character 1...
NODWEDDION
alwminiwm ocsid Brown yn cael ei asio a grisialu dan thymheredd uchel o gymysgedd o bocsit a deunyddiau crai eraill ac eraill. Mae'n cael ei nodweddu gan ei galedwch uchel, caledwch a siâp da o ran maint. Sgraffinyddion offer a wneir ohono yn addas ar gyfer malu metelau o cryfder uchel-tynnol fel: dur carbon, dur aloi cyffredinol-bwrpas, haearn hydrin anelio a broze caled, etc.It hefyd yn cael ei ddefnyddio fel deunyddiau gwresrwystrol.
Maint y Graean: 12 # -220 #;
Micropowder: 240#-1200#.
