金刚砂又名棕刚玉以优质铝矾土为原料，无烟煤，铁霄，通过采用在电弧冶炼。炉2200℃以上高温中提纯、除杂、结晶、分选、破碎、磁选、筛分等加工手段制成各种颗粒尺寸的产品。其质地致密、硬度高，粒形成球状，适用于制造陶瓷、树脂高固结磨具以及研磨、抛光、喷砂、精密铸造等，还可用于制造高级耐火材料。 棕刚玉具有纯度高，结晶好，流动性强，线膨胀系数低，耐腐蚀的特点。经数十家耐火生产企业实践验证，该产品在应用过程中具有不起爆、不粉化、不开裂的特点。 产品粒度按国际标准以及各国标准生产，可按用户要求粒度进行加工。通用粒度号为F4~F320，其化学成份视粒度大小而不同。突出的特点是晶体尺寸小耐冲击，因用自磨机加工破碎，颗粒多为球状颗粒，锐石牌棕刚玉具有纯度高，质地致密，堆积密度大，自锐性强，韧性好，磁性物含量特低的特点，用其制成的磨具磨削锋利，发热率低，磨削比高，且使用时沾附少；制成的烧结磨具具有烧成后颜色深蓝、不起网状裂纹、无锈斑的特点，适用于制造陶瓷、树脂高固结磨具以及研磨、抛光等。

With its dense texture, high hardness and the formation of spherical particles, it issuitable for the manufacture of ceramics and resin, as well as the high-Bonded Abrasives grinding, polishing, sand blasting, precision casting and so on, also can be used to manufacture high-grade refractory material. Brown Fused Alumina has high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion-resistant and other characteristics. Dozens of refractory manufacturers have proved in practice that the product has not detonate, non-powder, non-cracking characteristics in the application process. Particle size is in accordance with international standards and can be processed as requirements. Universal size: No. F4 ~ F320, its chemical composition varies depending on grain size. Its prominent feature is the small crystal size, impact resistance and spherical particles. This product has high purity, dense texture, large bulk density, strong self-sharpening, good toughness, low level magnetic material content and other characteristics.
