Brown Aluminum Oxide
Stutt lýsing:
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...
Eiginleikar
Brown ál oxíð er runnin saman við og var kristölluð undir háum hita úr blöndu af súráli og annarra og öðrum hráefnum. Það einkennist af mikilli hörku þess, gott Toughness og lögun I stærð. Slípiefni tools gerður úr þeim eru hentugur fyrir mala málma af hár-tensile styrkur such sem: kolefni úr stáli, i til almennra nota ál stáli, annealed sveigjanlegur Iron og mikillar Broze, etc.It einnig er hægt að nota sem svara illa efni.
Grit stærð: 12 # -220 #;
Micropowder: 240#-1200#.
