(1) tungsten steel, tungsten carbide, super hard alloy or hard alloy are the same ingredients, can be divided into three categories: P, M, K three.

P grade: suitable for processing low, medium and high carbon steel, alloy steel, tool steel, die steel..

M grade: suitable for processing difficult to process materials, such as stainless steel (SUS), malleable cast iron..

K grade: suitable for processing of cast iron, high speed steel (HSS), after heat treatment of the material..

(2) tungsten carbide is a compound composed of tungsten powder and carbon, chemical formula WC Carbide Tungsten in English, Carbide.

Tungsten carbide hardness high, Mohs hardness is 8.5~9.0, Hv: 1100~2200 melting point of 2870 degrees C, low resistance, no rust,

Insoluble in water, acid and alkali resistance, is one of the greatest inventions in the industry.

Pure tungsten carbide brittle, if a small amount of titanium, cobalt and other elements, can be divided into P, K, M three and according to their physical properties of different products,

Including discarded blades, end milling cutter, molding knife, wear-resistant parts, furnace structure, jet engines, gas turbines, nozzles, etc..

(3) production method of tungsten carbide

A, tungsten carbide powder:

The tungsten ore crushing and separating, and concentrate containing high tungsten content and the containing tungsten concentrate and carbide aluminum or calcium carbide hybrid heating

Reduction effect, when the temperature reached 2100 degrees C, the formation of tungsten carbide, cooling after grinding to a very fine powder and become tungsten carbide powder.

B, sintering process:

The tungsten carbide and cobalt are mixed in a certain ratio, and then the temperature is about 1300~1500 degree C. The process is in vacuum furnace.

In sintering, called semi sintering method, finally is placed into a vacuum furnace and heating to 2100 degrees C to complete the whole sintering and make tungsten carbide can completely sclerosis.
