Key Specifications/Special Features:
Tungsten carbide drawing dies for wires/barsTungsten carbide drawing dies are wise economical choice for steel wire and other large-size wire drawing applications that make cost savings a priority over die wear resistance and wire surface finish.Cemented carbide drawing dies are used in wire drawing industries and for drawing of different materials like mild steel (M.S), high carbon (H.C), stainless steel (S.S), brass, aluminum. All major wire producers use tungstencarbide drawing dies.Tungsten carbide drawing diesfromZhuzhou Huijin Cemented Carbide Co., Ltd are composed by micro crystalline rare refractory metal carbide and high-purity cobalt powder for auxiliary metal or other metal powder as the binder. As a result of special production methods, and use of international advanced low pressure sintering furnace, the alloy is not only to maintain the original valued properties of tungsten carbide, and its performance increased by 1/4 than ordinary drawing die. At the same time, due to cobalt or other metal for cement, it becomes also tough.1. Good wear resistance
Tungsten carbide possesses high wear resistance, which could guarantee long-term work of drawing die within any drawn amount and ensure the size and precision of products.
2. Excellent polishingCarbide has a good polishing, which can be processed like mirror, thus ensuring high-quality of metal surface.
3. Small adhesionIn the drawing process, the drawing die keep little adhesion with metal processed, thereby enhancing the durability of drawing die, and make processing material to acquire high-quality gloss finish for surface.
4. Small friction coefficientIn the drawing process, small frictional resistance can greatly reduce the power loss, thus enhancing efficiency.
5. High coefficient of thermal conductivityIn the drawing process, heat can be conducted away very well.
6. Good corrosion resistanceThe property is in the wet lubricated stretch, especially in the acidic lubricated stretch, to become more superior.
