镍合计等有色金属研磨用绿碳化硅800#研磨粉
镍合计等有色金属研磨用绿碳化硅800#研磨粉是一种硬脆型的研磨材料，它的硬度比金刚石略低，高于大部分其他人造磨料。此外，绿碳化硅还很好的高温性能稳定性和耐酸碱腐蚀性能，因此它是适合石材硬质材料的磨料和耐热耐高温的耐磨材料。
Green silicon carbide 800 # is a hard and brittle abrasive material, with a slightly lower hardness than diamond and higher than most other artificial abrasives. In addition, green silicon carbide has good high-temperature stability and acid alkali corrosion resistance, making it a suitable abrasive for hard stone materials and a heat-resistant and high-temperature resistant wear-resistant material.
