Brown te konumohe ōkai
Whakaahuatanga Poto:
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...
Tuhinga
tauta waikura konumohe Brown te ka ö i raro i tiketike pāmahana i te ranunga o te bauxite me ētahi atu, me te tahi atu rauemi mata. Kei te āhuatanga i te reira e tona pakeke tiketike, taikaha pai me te āhua i roto i te rahi. He pai mō te huri konganuku o kaha nui-kurut pērā i Abrasives taputapu i hanga o reira: waro maitai,-whakaaro whānui koranu maitai, annealed rino māngohe me broze pakeke, etc.It taea te whakamahi hoki rite ngā rauemi whakangutungutu.
Rahi toheroa: 12 # -220 #;
Micropowder: 240#-1200#.
