Marrón óxido de aluminio
Breve descripción:
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...
CARACTERISTICAS
óxido de aluminio Brown se fusiona y se cristalizó bajo alto de temperatura de una mezcla de bauxita y otros y otras materias primas. Se caracteriza por su alta dureza, buena tenacidad y la forma de tamaño. Abrasivos herramientas hechas de él son adecuados para la molienda de metales de fuerza de alta resistencia, tales como: acero al carbono, acero de aleación de propósito general, de hierro maleable recocido y Broze duro, etc.It también se puede utilizar como materiales refractarios.
Tamaño de grano: 12 # -220 #;
Micropowder: 240#-1200#.
