Why choose Tungsten carbide in tooling？
Heat Resistance – and is very valuable in applications where a combination of minimum deflection and good ultimate strength is the first consideration.
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
Impact Resistant – For such a hard material with very high rigidity, the impact resistance is high.
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.
Impact Resistant – For such a hard material with very high rigidity, the impact resistance is high.
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.
Stability – Highly resistance to deformation and deflection undergoes no phase changes during heating and cooling and retains its stability indefinitely. 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.Tungsten carbide retains toughness and impact strength in the cryogenic temperature ranges. (-453°F.)
Thermal Conductivity –It is in the range of twice that of tool steel and carbon steel.
Electrical Conductivity – Equal to that of tool steel and carbon steel.
Weight – The specific gravity of tungsten carbide is from 1-1/2 to 2 times that of carbon steel.
Coefficient of Friction – Tungsten carbide compositions exhibit low dry coefficient of friction values as compared to steels.
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.
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.
Weichuang is specialized in manufacturing carbide heading dies and has been putting effort to improve wear-resistance, increase the life of the tool and also enable higher working speeds and feeds to be achieved.
