Title What is the abrasive material of the T41 green cutting disc size?
Description With the increasing market size of T41 green cutting disc size, there are many companies that produce cutting discs on the market. The size of the cutting discs produced by different companies is different from the materials used, and for some users who have not touched the cutting discs. I don’t know what the basic material of the production cutting disc is. Today, the professional cutting disc manufacturer Aurora Abrasives gives you an analysis of some abrasive materials for the production of cutting discs. Commonly used abrasives for T41 green cutting disc sizeinclude brown jade (A), white corundum (wA), black corundum (BA), black silicon carbide (c), etc. The most commonly used is brown fused alumina, because brown fused alumina has high hardness and toughness. The particles are sharp, the applicability is strong and the price is lower than other abrasives. Brown fused alumina is divided into primary sand and secondary sand according to its reduction during smelting, mainly in chemical composition: Al2O3 content of primary sand is ≥94.5; Al2O3 content of secondary sand is <94.5%; generally 85% Left and right, and the Fe2O3 content is 4 to 5%; therefore, the secondary sand hardness is lower than that of the primary sand, but the price is also low; the brown corundum is suitable for the processing of various carbon steels and general alloy steels; the white corundum is higher in hardness than the brown corundum. It has large brittleness and small grinding heat. Because of its high price, it is used for heat deformation of workpieces. It is also used as a mixed abrasive for special material processing. The content of Al2O3 in black corundum is 70-85%, and the content of Fe203 is 7-9. Low hardness, poor cutting force, but the price is also cheap; black silicon carbide has high hardness and good brittleness, sharp cutting edge, good self-sharp performance, good thermal conductivity, and advantages in processing non-ferrous metals, plastics, rubber and cast iron.
