High out-put black silicon carbide grain 180# for wheel abrasives

1 Product description Its hardness is between fused alumina and diamond. Mechanical intensity of it is higher than fused alumina. It is crisp,sharp and have certain degree of conductive heat.Black silicon carbide is higher toughness than green silicon carbide with sic purity 98%,it has been used for processing low tensile strength of material, such as glass, ceramics, stone, refractory materials, cast iron and nonferrous metal, etc.Green silicon carbide can also be used in refractories and electronic semiconductor industry. 2.Product index Physical index Color Black Moh's hardness 9.2 True density 3.2-3.45g/cm3 Melting point 2250℃ Maximum operation temperature 1900℃ 3 Chemical index SiC 98% SiO2 1% H2O 0.5% Fe2O3 0.3% F.C 0.3% 4.Product model grit 16# 20# 22# 24# 30# 36# 40# 46# 54# 60# 70# 80# 90# 100# 120# 150# 180# 220# 240# 4.Product advantage (1)having sharp knife-edge (2)electrical conductivity, thermal conductivity (3)high working efficiency (4)Highly friable abrasive media which is reusable but less durable than brown aluminum oxide 5.Product application (1)Clean the high hardness surface, such as: tungsten steel work piece. (2)Suit for all kinds of metal and non-metal with low tensile strength’s processing. (3)Cut the friable work piece. (4)Abrasives, mainly used for grinding wheel, abrasive paper, abrasive belt, (5)Sandblasting derusting,stainless steel products, steel, steel pipe, steel (6)Grinding high-speed,high carbon steel 6.Others (1) We are factory.So you do not have to worry about quality and price, we can guarantee the best quality and the most reasonable price. (2) We could offer the sample for free charge but do not pay the cost of freight. (3) Terms of payment: Payment<=1000USD, 100% in advance.
