sell white fused alumina/corundum

Description

White fused alumina White fused alumina is electrically fused in arc furnace with high grade Bayer&#**9;s process alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. Abrasives tools made of it are suitable for grinding high-speed, high carbon steel, etc. It also can be used as materials for grinding and polishing, precision casting, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials, etc. 1) For refractories materials Specification(&#***0;): Al2O3 *9%Min Na2O 0.5%Max Size **1mm/**3mm/**5mm/**8mm/***5mm/****0mm/***0mm Specification(&#***1;): Al2O3 *8.5%Min Na2O 0.5%Max Size **0mesh/**0mesh/**5mesh 2) For abrasives For bonded abrasives Chemical composition (weight %) Grit NO.
