Brown óxido de aluminio
Breve Descrición:
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...
CARACTERÍSTICAS
óxido de aluminio de Brown é fundido e cristalizado baixo a alta temperatura a partir dunha mestura de bauxita e outros e outras materias primas. Caracterízase pola súa dureza elevada, boa dureza e forma en tamaño. Abrasivos ferramentas feitas de que son axeitados para a moenda de metais de alta resistencia, tales como: aceiro de carbono, aceiro liga de propósito xeral, ferro maleable recocido e Broze duro, etc.It tamén poden ser utilizados como materiais refractarios.
Tamaño do gran: 12 # -220 #;
Micropowder: 240#-1200#.
