    1. Brown Fused AluminaBrown fused alumina is produced from high quality bauxite . This process is conducted via the 3500 KVA electric arc furnace at a temperature higher than 2200℃. The process of products :bauxite broken into crushing machine --- elevating -- roll crusher mill-- sizing ---magnetic separator ---fine sieve ---water washing (acid washing )---package (25kg/pp bag or paper bag ,40 bags / ton bag or pallet ). Our brown fused alumina covers two production lines. The F type is mainly...
    1. White Fused AluminaWhite fused alumina consist of high grade aluminum that is processed through an electric furnace at high temperatures of up to 2,000 degrees centigrade. The resulting product retains superb purity and is extremely resilient to deformation as well as acids and alkalis. In contrast with brown fused alumina, the white version possesses higher levels of hardness but lower tenacity. Apart from being used for the grinding...
    1. Black Silicon CarbideBlack silicon carbide exhibits good electrical and thermal conductivity, desirable traits in many applicable situations. It is borne from the combination of quartz sand and petroleum coke, processed via a high temperature resistance furnace. The resulting hardness is rated higher than fused alumina but lower than synthetic diamond. Brittle and sharp, this substance is capable of mechanical intensity superior to that of the...
    1. Green Silicon CarbideOur green silicon carbide strictly adheres to FEPA specifications for bonded F8- F2000 and coated P12-P2500. A product of high purity materials and salt additives, the carbide is forged through a resistance furnace at an approximate temperature of 2200℃. The resulting product is a semi-conductor with excellent thermal conductivity. Appearing as a dark green translucent hexagonal crystal, this substance possesses a ...
    1. Green Silicon Carbide PowderGreen silicon carbide powder is commonly used for heavy duty grinding, polishing, and lapping procedures. A product of petroleum coke, quartz sand, and other materials, it is manufactured in essentially the same fashion as the black silicon carbide. While the procedures is similar, this abrasive has proven itself to be of higher purity and retains a greater hardness when compared to the black silicon carbide. ..
    1. Walnut SandWalnut sand produced by our company is refined from walnut shell and its appearance is in compliance with international industrial standards. Silicone free and low in hardness, it can be used for the cleansing of metal, alloy, electronic rubber element, as well as gasoline and diesel engines without visible surface damage. The abrasive can also be used to polish and lap glass, watch, gold and silver jewelry, etc. When supplied with...
