Product Description
Tungsten carbide,also called "Hard metal",is a kind of sintered material by WC powder and Binder(usally Cobalt,Titanium,etc) under temperature 1480ºC-1500ºC,Different Grades of Tungsten Carbide will differ in Strength, Rigidity, and other Properties.
- 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.- Strength: Tungsten carbide has very high strength for a material so hard and rigid. Compressive strength is higher than virtually all melted and cast or forged metals and alloys.
- Rigidity: Tungsten carbide compositions range from two to three times as rigid as steel and four to six times as rigid as cast iron and brass. Young's Modulus is up to 94,800,000 psi.
- Heat and oxidation resistance: Tungsten carbides perform well up to about 1000°F in oxidizing atmospheres and to 1500°F in non-oxidizing atmospheres.
- Low temperature resistance : 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.
- Coefficient of Friction: Tungsten carbide compositions exhibit low dry coefficient of friction values as compared to steels.
- Corrosion 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.
| Material | Thermal Conductivity (the higher,the better) | Expansion coefficiant (the lower,the better) | Hardness(Mohs) (the higher,the btter) | Cost |
| Brass | 120 | 18.5 | 2.5 to 4.0 | low |
| SS | 20 | 8.0 | 5.0 to 7.0 | low |
| Tungsten carbide | 167 | 4.5 | 6.0 to 8.5 | medium |
| sapphires | 42 | 5.3 | 8.5 to 9.0 | high |
| Diamonds | 2300 | 1.0 | 10 | high |
| Titanium | 22 | 8.6 | 5.5 to 6.0 | high |
Professional supplier for tungsten carbide products
We specialize in carbide 3D nozzles since 2018, during last year, we met several problems and solved them,our nozzles have passed test of time from our customers.
All Common Dimensions are available
Except for orifice Φ0.4/Φ0.6/Φ0.8mm, we own molds for other common innner orifices(Φ0.25/Φ0.5/1.0mm) too.you don't need pay mold cost for all these existed dimensions.
Customized Design is more than welcome too
We encourage customization as your own design with MOQ request.
Unbeatable price performance ratio
Carbide 3D nozzles beat any other material nozzle on price performance ratio,Oston price is competitive too.
