Bruna Aluminium Oxide
Mallongaj Priskribo:
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...
TRAJTOJ
Bruna rusto de aluminio estas kunfandita kaj kristaliĝis sub alta temperaturo de miksaĵo de bauxita kaj aliaj kaj aliaj krudmaterialoj. Ĝi karakterizas por lia alta malmoleco, bona fortecon kaj formon en grandeco. Abrasives iloj farita el ĝi estas taŭga por muelantaj metaloj de alta tensile forto kiel: karbono ŝtalo, ĝenerala intenco alojo ŝtalo, Annealed modlebla fero kaj forte broze, etc.It ankaŭ povas esti uzata kiel obstinaj materialoj.
Grit grandeco: 12 # -220 #;
Micropowder: 240#-1200#.
