河南伊川供刚玉、一级金刚砂、亚白刚玉、以

众邦棕刚玉以优质铝矾土为主要原料，通过采用在电弧冶炼炉2200℃以上高温中熔炼提纯，并经结晶、分选、破碎、磁选、筛分、水洗、酸洗等加工方法制成各种颗粒尺寸的产品。具有硬度高、任性大、抗冲击、耐高温、抗氧化、耐腐蚀等特点。通常用于制造陶瓷树脂磨具、切割片、喷砂、砂带、砂纸，并且是各种耐火材料及防滑耐磨跑道的首选原料。

ZhongBang Brown Fused Alumina is made by high-quality bauxite as main material, fusing and purifying in a pouring electric arc furnace at a temperature of over 2200℃. and made into different grain size through crystal, choosing, crashing, magnetic, separating, screening, washing and acid cleaning, etc. It has the characteristics of high hardness, high toughness, resistance of high-temperature, anti-oxidation, corrosion resistance, etc. It is widely used in the area of making ceramic coated abrasives, cutting, sandblast, abrasives belt, sandpaper, and also it is an ideal material of making all kinds of refractories and skid-proof raceway.
