白刚玉

白刚玉磨料,白刚玉,白刚玉块,白刚玉磨具,白刚玉砂(WA)
白刚玉磨料是以氧化铝为原料，经高温熔炼而成。呈白色，硬度比棕刚玉略高，韧性稍低。用白刚玉制造的磨具适用于高碳钢、高速钢和淬火钢等的磨削。白刚玉磨料,亚白刚玉磨料可作研磨抛光材料，还可作精密铸造型砂、喷涂材料、化工触媒载体、特种陶瓷、高级耐火材料等。
白刚玉磨料性能：白色、较棕刚玉硬而脆，切削力较强，化学稳定性好，具有很好的绝缘性。
白刚玉磨料适用范围：可做固结构及涂附磨具，湿式或干式喷射砂，适合晶体、电子行业的超精研磨和抛光及制作高级耐火材料等。适合加工淬火钢、合金钢、高速钢、高碳钢等硬度较硬，抗张强度较大的材料。白刚玉磨料还可用做触媒体，绝缘体以及精密铸造砂等。
WHITE FUSED ALUMINA(WA)
Its main raw material is abayer alumina,which is electrically fused in high temperature.It is white and its hardness is higher,but toughness lower than that of brown fused alumina.The abrasive tools made of it are suitable for the grinding of high carbon steel and chilled steel.It can also be usedd as polishing materials and precision founding sand,spraying and coating materials,catalyst carrier,special ceramics and super refractory materials.
Property:IT is white and hard and more brittle than A.It features strong cutting force and steady chemical property and excellent insulation.
Usage:It can be used for making bonded and coated abrasive tools,wet or dry blasting.It is also sutable for super precision grinding and polishing of crystal and electronic industry and making high quality refractory materials.It can be adopted for the grinding of the hard and strong bending stength materials such as chilled steel,alloy steel,high-speed steel and high carbon steel.Meanwhile,it can be used as catalyse carrier,insulator and presicion founding sand,etc.
