Product Description

In standard parts industry, tungsten carbide cold heading dies need to under great unit pressure in cold upsetting deformation process , when a large degree of deformation and material hardness, units of pressure up to 2000MPa more. At the same time the metal flow intense, thus requiring tungsten carbide cold heading dies have high strength, good fatigue resistance, high hardness and good fatigue resistance, in order to ensure the cold heading dies under high pressure without breaking, deformation and wear resistance.Tungsten carbide cold heading die raw material is produced by powder metallurgy composite materials, which have high hardness, wear resistance,life is several times and several hundred times than ordinary cold heading die. With carbide manufacturing standard tungsten carbide cold heading die, not only have high dimensional accuracy of parts, but also greatly improve the life of the cold heading die, can create good economic and social benefits.


Carbide is made of rare and very fine particles of refractory carbide (WC) and metallic cobalt as a binder composition. Due to the special method for producing such alloys remains the original characteristics of the tungsten carbide, its hardness close to diamond, and because of cobalt as a binder, it also has the toughness. Tungsten carbide cold heading dies material has the following characteristics:

1. High wear resistance. Tungsten carbide cold heading dies material high wear resistance, tensile modulus can be guaranteed long-term work in any degree of deformation, ensuring standard size unchanged.

2. Excellent in polishing. Carbide has a good polishing, can be processed into the die hole mirror light, ensuring high quality standard surface.

3. Adhesion to metal is small. In the tungsten carbide cold heading process, ferrous metal material adhesion small carbide tooling materials, ensuring a high tungsten carbide cold heading die life.

4. The friction coefficient and energy consumption is small.

5. High thermal conductivity. Since the thermal conductivity of the tungsten carbide die is high, heat generated during the cold forging can quickly conducted away to improve the durability of the mold.

6. Good corrosion resistance.

BENEFITS OF TUNGSTEN CARBIDE IN TOOLING

Strength – Tungsten carbide has very high strength for a material and is extremely hard and rigid. Compressive strength is higher than almost all melted, cast, forged metals and alloys.

Rigidity – Tungsten carbide compositions range from (2) to (3) times as rigid as steel and (4) to (6) times as rigid as cast iron and brass. Young’s Modulus is up to 94,800,000 psi.

Heat Resistance – Tungsten Carbide is highly resistance to deformation and deflection and is very valuable in applications where a combination of minimum deflection and good ultimate strength is the first consideration.

Impact Resistant – For such a hard material with very high rigidity, the impact resistance is high.

Heat and oxidation resistance – Tungsten-base carbides perform well up to about 1000°F in oxidizing atmospheres and to 1500°F in non-oxidizing atmospheres

Low temperature resistance (cryogenic properties) – Tungsten carbide retains toughness and impact strength in the cryogenic temperature ranges. (-453°F.)

Thermal Conductivity – Tungsten carbide is in the range of twice that of tool steel and carbon steel.

Electrical Conductivity – Tungsten carbide is in the range equal to that of tool steel and carbon steel.

Specified Heat – Tungsten carbide ranges from about 50% to 70% as high as carbon steel.

Weight – The specific gravity of tungsten carbide is from 1-1/2 to 2 times that of carbon steel.

Hot Hardness – When temperature increases to 1400°F, tungsten carbide retains much of its room temperature hardness. At 1400°F, some grades equal the hardness of steels at room temperature.

Tolerances – Many surfaces or even complete parts can be used the way they come from the furnace, “as sintered”, such as mining or drilling compacts. In those parts requiring precision ground accuracy, such as stamping dies, close-tolerance preforms are provided for grinding or EDM.

Methods of Fastening – Tungsten carbide can be fastened to other materials by brazing, epoxy cementing or mechanical means. Tungsten carbide’s low thermal expansion rate must be carefully considered when preforms are provided for grinding or EDM.

Coefficient of Friction – Tungsten carbide compositions exhibit low dry coefficient of friction values as compared to steels.

Galling – Tungsten carbide compositions have exceptional resistance to galling and welding at the surface.

Corrosion-Wear Resistance – Specific grades are available with corrosion resistance approaching that of noble metals. Conventional grades have sufficient resistance to corrosion-wear conditions for many applications.

Wear-Resistance – Tungsten carbide wears up to 100 times longer than steel in conditions including abrasion, erosion and galling. Wear-resistance of tungsten carbide is better than that of wear-resistance tool steels.

Surface Finishes – Finish of an as-sintered part will be about 50 micro inches. Surface, cylindrical or internal grinding with diamond wheel will produce 18 micro inches or better and can produce as low as 4 to 8 micro inches. Diamond lapping and honing can produce 2 micro inches and with polishing as low as 1/2 micro inch.

Dimensional Stability – Tungsten carbide undergoes no phase changes during heating and cooling and retains its stability indefinitely. No heat treating is required.
