Green vs Black Silicon Carbide
White corundum is refined from high-quality alumina powder by electric melting. High purity, good self-sharpening, acid and alkali corrosion resistance, high-temperature resistance, and stable thermal performance. Its hardness is slightly higher than brown corundum. Strong grinding capacity, low heat generation, and high efficiency. It can be used for grinding fine grain abrasives such as high carbon steel, high-speed steel, and stainless steel, as well as for precision casting and high-grade refractory materials.
After sandblasting, the surface is white, without any impurities, and without cleaning. Fine white corundum can be used as a first polish. Can also be used as a variety of product additives.
White corundum powder is harder and more brittle than brown corundum and has a stronger cutting force. Good chemical stability, good insulation. Scope of application:
It can be used for solid structure and coating abrasives, wet or dry sandblasting, suitable for crystal, electronics, and other industries ultrafine grinding and polishing, and advanced refractory material production. Suitable for processing hardened steel, alloy steel, high-speed steel, high carbon steel, and other high hardness, high tensile strength materials. White corundum abrasives can also be used as contact media, insulators, and precision casting sand.
With good self-sharpening, small calorific value, strong grinding ability, and high efficiency, the price is higher than brown corundum. White fused alumina powder is suitable for high-hardness steel, such as high-speed steel, high carbon steel, hardened steel, alloy steel, etc. Ideal for wet sandblasting and polishing applications, for ultra-fine grinding and polishing in the crystal and electronics industries, and for the production of advanced refractories.
The content of alumina in white corundum powder is more than 98% and contains a small amount of iron oxide, silicon oxide, and other components. Corundum has excellent high-temperature performance and mechanical strength and is widely used in metallurgy, machinery, the chemical industry, electronics, and other industrial fields. As an abrasive, white corundum powder is widely used in abrasive grinding machines. There are many kinds of white fused alumina, and the uses of different kinds of corundum are different.
