Brown alumīnija oksīds
Īss apraksts:
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...
IESPĒJAS
Brown alumīnija oksīds ir kondensēts un kristalizēta ar augstu temperatūru no maisījuma boksītu un citu un citu izejvielu. To raksturojas ar augstas cietības, labu stingrību un formas lieluma. Abrasives instrumenti, kas to ir piemērotas slīpēšanas metālu augstas stiepes izturību, piemēram: oglekļa tērauda, vispārējas nozīmes leģētā tērauda, rūda kaļamā dzelzs un cieto Brože, etc.It arī var izmantot kā ugunsizturīgu materiālu.
Smiltis izmērs: 12 # -220 #;
Micropowder: 240#-1200#.
