Resin & Vitrified Bond Diamond

It is a carefully designed synthetic diamond having the optimum performance on various nonferrous materials. from the tough blocky crystal shape to highly fragile irregular shape, the specific crystalline structure can achive higher material removal rate in dry or wet grinding, as well as surface finishes.
The applications: tungsten carbides, carbide-steel combinations, glass, advanced ceramic
COATED ABRASIVE

made from Ap-17, it is calcined at 1000oC-1300oC, the grit inside crack will be well repaired after heating, the toughness also will be improved after heating. Then the grits will be well washed and carefully sieving again to kicked off the needle and flake shape . It is used for making high quality coated abrasives products like abrasive waterproof paper, sanding cloth, sanding belt, flap wheel a
Stainless Steel Fiber

The products reach foreign similar products advanced level in the performances, and have applied extensively in various stove vaults of the industrial field such as metallurgy,cement,petroleum,chemical engineering and porcelain etc,and also are used in bridge\tunnel\highway\moreover get the good effect of prolonging of service life in the applying part about 2 to 6 times of the similar products
Fused Spinel

Manufactured from high pure raw materials in electric arc furnace, with high bulk density and resistance to thermal shock and chemical corrosion at high temperature, Fused Magnesite-Alumina Spinel can be used for making high performance castables,silide nozzle and ladle linings brick,etc.
SILICON CARBIDE BLACK

It is one kind of black silicon carbide abrasives grain, To get the kind of grains, we specially process the ingots, separate the magnetic material, and sieve the grains carefully to get a complete range of grit sizes.
As an abrasive, CF-16 is used in making vitrified bonded grinding wheels, resign bonded grinding wheels. As loose grains, it is widely used for pressure blasting, surface finish
SYNTHETIC DIAMOND & CBN

SMD series is a kind of saw grade industrial diamond product for sawing of stone, concrete and geological drilling. This type fo product is suitable for making frame saw, wire saw, muti-blades and drill bits. Workpieces range from hardest granite, asphalt, refractories and reinforced concrete to softer marbles, limestones and lightweight building materials.
The premium grade SMD5190, 5180, 516
Metal Bond Diamond

It is a kind of superabrasive with yellow monocrystalline colour used for producing metal bond diamond tools. According to the toughness grade high, medium and low, this kind of product can be classified to MBD8, MBD6 and MBD4. They are mainly used for producing high quality metal bonded abrasive tools.
BROWN FUSED ALUMINA

The grains of this kind of product crashed by ball mill machine, its grain shape is more blocky than rolling machine made grains, but its bulk density is less than AE-17 grains. With the medium loose bulk density, and after water washing, strong magnetism removing, very carefully sieve classifying, this kind of abrasive grain normally can match the various vitrified bond abrasive products applicat
Monocrystalline Fused Alumina

It is electrically fused from a mixture of bauxite, iron sulfide, etc. It is yellowish or gray, with strong grain shape, great hardness, toughness and impact strength, hence it is particularly adaptable for the grinding of stainless steel, high vanadium-high speed steel, and is especially used for the grinding of easy-deformed and easy-burned parts.
Boron Carbide

It is smelted from boric acid and powdered carbon in electric furnace at high temperature. With the high hardness at 4950kg/cm2, it is suitable for a variety of application.
