Brown Fused Alumina with Middle Temperature Treatment
Brown Fused Alumina with MiddleTemperature Treatment
This kind of Brown Fused Alumina grains is calcined at the high temperature, and with the anneal treatment.It is characterized by very low coefficient of linear expansion,very good hydrophilicity, good toughness and high hardness, producing the sintered grinding tools that is characterized by deep blue color after firing, without resillage, without rust and so on. So our this kind of product increase the precision and grinding abilityof the grinding tools in the using course. Brown Fused Alumina with middletemperature treatment is applicable to make high quality bonded abrasives.
