Brown aluminij oksid
Kratki opis:
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...
ZNAČAJKE
Smeđa aluminij oksid kondenzirana i kristalizira u visokom temperaturom u smjesi boksita i drugih i drugih sirovina. Ona se odlikuje visokom tvrdoćom, dobre otpornosti i oblika u veličini. Abraziva alati izrađeni od toga su pogodni za brušenje metala visoke čvrstoće snage, kao što su: ugljični čelik, za opće namjene, legirani čelik, ciklozorani kovan željeza i tvrdi broze, etc.It se također može koristiti kao vatrostalnih materijala.
Veličina pijesak: 12 -220 # #;
Micropowder: 240#-1200#.
