WA fine surface grinding artificial abrasive high hardness and high purity white corundum
Product name: grained sand of white fused alumina
specification: 180#
Performance : white, harder and brittle than brown corundum, strong cutting force, good chemical stability, and good insulation.
Scope of application : It can be used as a fixed-grade coated abrasive, wet or dry jet sand, suitable for ultra-precision grinding and polishing in the crystal and electronic industries, and for the production of refractory materials. It is suitable for processing hardened steel, high-speed steel, high-carbon steel and other materials with hard hardness and high tensile strength. It can also be used as a contact medium, insulator and precision casting sand. It is widely used in grinding and polishing of aluminum, steel, stainless steel, stone, glass, etc. Since its launch on the market, it has been well received by users, especially in the grinding and polishing of stainless steel, copper and other metal materials and glass industry, which fully shows the superior performance of the product. Among them, 3000 mesh, 4000 mesh, 6000 mesh are used for grinding and polishing in the piezoelectric crystal industry, and 8000 mesh, 10000 mesh series products are mainly used for polishing stainless steel.
