Black fused alumina (lower aluminium oxide abrasive)is a new type abrasive material for polishing various metal.Black aluminium oxide abrasive is featured with high hardness, strong tenacity, good self-sharpening, better cohesisness, higher durability, less heat generated in grinding and giving the metal works high finish, less power weakened in grinding.It is mostly used in grindin and polishing stainless steel, metal works , optical glass, bamboo or articles.And it is also the new grinding material of producing colophony grinding wheels, slice, and emery cloth.
Grit size:
White fused alumina sand was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-al2o3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
Brown fused alumina are the perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, and lapping and polishing processes. While aluminum oxide has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important.
1. Refer the carbide blanks , we adopt yg7, (7%cobalt) , this grade is kennametal gave us this grade , that's why we also supply the carbide blanks to kennametal , yg1
2. Anyway , until now , the all customers whatever in usa, canada , or japan, italy are satisfied with the quality of our burrs.
3. Our machines are five-axis cnc that much better than others' 3-axis cnc
4. Original material (tungsten) not recyclable powder
5. Adopt the lucas-milhaupt for braze , 35 crmo alloy steel for shanks.
6. Silver brazing£¬grade is bag24£¬welding temperature is 680-730¡æ
7. The best quality , the longest lifetime in china recently.
1.Quality of carbide threading inserts is equivalent to vargus, but we have good price.
2.All of our tungsten carbide products are made from the high ¡§cpurity original /virgin material, pressed ( extrusion) and sintered but not recycle powder .
3.The samples can be sent to you if you need them to test.
4.Pls check in attachment that pictures of carbide threading inserts.
We produce carbide rod with high quality & very competitive price for 15 years in china; hope to find a way to cooperate with you.
The samples can be sent to you if you need them to test.
We are specilised in providing our customers with carbide drawing die for drawing metal wires, our products are with the good wear resistance, exellent polishing, samll adhesion, small friction coefficient and good corrosion resistance
B4C ceramic with small density, high hardness, ultra high modulus and fracture toughness produced by our know-how is a new generation of light armor ceramic these tiles are combined with ultra high molecular weight polyethylene into anti-ballistic panels which are the ideal choice of human body, vehicle and armed helicopter protection. Shooting tests showed our plates meet nij level iii/iv stipulated by U.S. Standard NIj0101.06.
Black silicon carbidedescription
Black silicon carbide is produced at high temperature in an electric resistancetype furnace with quarts and petroleum as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused fused alumina. It is brittle and sharp and has electrical and heat conductivity in some degree. The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive.

White fused aluminum oxide is electrically fused in the furnace with high-grade alumina powder as raw materials. It has higher hardness and slightly lower toughness than brown fused aluminum oxide, characte-rized by its high purity, strong grinding ability. Abrasive tools made of it are suitable for grinding highspeed steel, high carton steel, etc. It also can used as materials for grinding and polishing precision-casting, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials, etc.
