Brown Aluminium Oxide
Luv hauj lwm:
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...
NTA
Brown txhuas oxide yog fused thiab crystallized nyob rau hauv kub ntawm ib tug sib tov ntawm bauxite thiab lwm yam thiab lwm yam raw cov ntaub ntawv. Nws yog yus muaj los ntawm nws cov high hardness, zoo toughness thiab zoo nyob rau hauv loj. Ntxhib no los txhuam cov cuab yeej ua rau nws ua yog tsim kev sib tsoo co ntawm high-tensile zog xws li: cov hlau, general-lub hom phiaj hlau steel, annealed malleable hlau thiab nyuaj broze, etc.It kuj yuav siv tau raws li refractory cov ntaub ntawv.
Zeb loj: 12 # -220 #;
Micropowder: 240#-1200#.
