Brun aluminiumoxid
Kort beskrivelse:
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...
FUNKTIONER
Brun aluminiumoxid fusioneres og krystalliseret under høj temperatur fra en blanding af bauxit og andre og andre råvarer. Det er karakteriseret ved dets høje hårdhed, god sejhed og form i størrelse. Slibemidler redskaber af det er egnede til slibning metaller af høj trækstyrke såsom kulstofstål, generelle formål legeret stål, udglødet smedbart jern og hårdt Broze, etc.It også kan anvendes som ildfaste materialer.
Kornstørrelse: 12 # -220 #;
Micropowder: 240#-1200#.
