Silicon carbide abrasives
Silicon carbide abrasives are divided into black silicon carbide and green silicon carbide, which have high hardness and high wear resistance. The hardness of black silicon carbide reaches Mohs 9.2, which is suitable for processing general metal materials such as iron, steel, and copper; green silicon carbide has a higher hardness and is suitable for grinding high-hardness alloys, optical glass and other materials. The hardness of silicon carbide is second only to diamond, and it has excellent corrosion resistance and is suitable for harsh environments such as strong acids and strong alkalis.
Brown corundum abrasive
Brown corundum abrasive has a low aluminum oxide content, usually 93-96%, which is suitable for large-scale sandblasting and cutting. Brown corundum has high toughness and is suitable for surface treatment of metals, glass and other materials. The quality of brown corundum varies greatly, so you need to pay attention to its purity and smelting process when choosing.
White corundum abrasive
White corundum abrasive has an aluminum oxide content of up to 99% and a high hardness, making it suitable for fine grinding and polishing. White corundum is suitable for fine grinding of aluminum alloys, stainless steel, and metals, as well as surface treatment of non-metallic materials such as acrylic, plastic, and glass. White corundum has good self-sharpening properties and is suitable for occasions that require high-precision processing.
