金刚砂的使用范围：The scope of application of silicon carbide 

1.喷砂——硬度适中，堆积密度高，无游离二氧化硅，比重大，韧性好，是理想的“环保”型喷砂材料，广泛应用于铝型材，铜型材玻璃，水洗牛仔服精密模具等领域；

1. Sandblasting, moderate hardness, high packing density, no free silica, than major, good toughness and is the ideal "environmental protection" type sand blasting materials, widely used in aluminum, copper profile glass, washing jeans precision molds, and other fields; 

2.自由研磨——研磨级磨料，应用于显象管、光学玻璃、单晶硅、镜片、钟表用玻璃、水晶玻璃、玉器等领域的自由研磨，是国内普遍采用的高级研磨材料；

2. The free abrasive, abrasive abrasive, applied to the tube, optical glass, monocrystalline silicon, lenses, clocks with glass, crystal glass, jade in areas such as free grinding, grinding is adopted widely in the domestic advanced materials; 

3.树脂磨具——磨料具有颜色合适、硬度好、有韧性、合适的颗粒断面类型和刃口保持度，应用于树脂磨具，效果理想；

3. The resin abrasive, abrasive has color appropriate, good hardness and toughness, suitable particle cross section type and keeping degree blade, used in resin abrasive, effect is ideal; 

4.涂附磨具——是砂纸、纱布等生产厂家的生产原料；
