Emery general term, silicon carbide, also can be brown fused alumina, also can be a black corundum SiC, also known as silicon carbide, or white corundum.Pure is a colorless crystals, density of 3.06-3.20.Hardness is very big, is about 9.5 degrees Morse, generally is colorless powder particles, after grinding, can be used as a polishing powder, polishing paper could be prepared, but also grinding wheel and strop friction surface.By the sand and the right amount of carbon in electric furnace to strengthen heat.
emery characteristics
Emery inside contain no cause silicosis free silicon harmful substances, do not contain toxic or radioactive pollution of heavy metals, because the product density is larger, seldom produce dust, effectively guarantee the operator's health, in addition, the characteristics of the low consumption and recycled products can greatly reduce the waste after the products use processing and cost.

Green emery powder/polishing carborundum
Green Silicon Carbide is made of petroleum coke and high quality silica as the main raw material, salt as the additive and smelted in the resistance furnace at high temperature.Green crystal, crisp and sharp, and has a certain thermal and electrical conductivity.The micro structure is hexagonal crystal.
purpose:
1. it are suitable for grinding high-speed,high carbon steel
2.high-grade refractory materials
3.abrasives tool
4.grinding and polishing
5.ceramics
6.sandblasting
White fused alumina powder /emery/corundum
1. Description:
White Alumina powder is fused from high quality bayer aluminum in high temperature. Its hardness is higher but toughness lower compared with Brown Aluminum Oxide. It is characterized by high purity, excellent self-sharpening, efficient grinding efficiency, and low frictional heat. It can withstand acid and alkali erosion, with high temperature resistance and good thermo stability.
2. Applications:
The abrasive tools made of it are suitable for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as lapping and polishing medium, precision founding sand, coating materials, catalyst carrier, special ceramics and super refractory materials.
3. Advantages:
a. Use imported Bayer aluminum; assure the high quality of products.
b. Equipped full line of test method. The laboratory is certified by government Inspection Bureau, that assures its quality stability.
c. Products are classified chemical washed, non-washed, shaped, non-shaped, normal bulk density and high bulk density. All products will be supplied according to customers different requirements.
