Tungsten carbide material features extreme wear resistance and hardness. The material is typically forged by the reaction of tungsten (W) metal and carbon (C) at 1400 to 2000°C. The result is a grey powder that can be pressed and formed into virtually any shape. When processing the powder into a shape, manufacturers use either a nickel or cobalt-bonding agent. Several chemical compositions can be used to provide better properties for varying applications.Tungsten carbide bushing applications is wide, which is a device to protect a class of components. It is in the actual work and the role and purpose of its application environment have a great relationship. Valve applications, bushings be installed in the valve stem cap trap, in order to reduce the valve leakage, to seal; bearing applications, the use of bush to reduce wear between the bearing and the shaft seat, avoid the gap between the shaft and the hole increases and so on.

product applicationPrecision wear-resistant tungsten carbide sleeveTungsten carbide bushing production and processing of high-strength, can withstand prolonged load, with high chemical stability,
alkali, alcohol, ether, hydrocarbons, acid, oil, detergent, water (sea water), and has no smell , non-toxic, tasteless, non-rust characteristics, its widely used in petrochemical industry for Submerged Oil Pump, slurry pump, water pump, Centrifugal Pump,etc.
Production process and finishing of cemented carbide:1. 100% fresh material with strict inspection.2.Preparative mixture： The raw materials would be fully blended together with ball milling machine, makes the powder ingredients homogenize,to obtain corresponding mixture particle size .3.Spray drying：With high purity nitrogen protection in a fully enclosed environment, the mixture oxygen is effectively reduced, material purityis effectively guaranteed, material dirty are prevented. and the particles are fine and uniform with good fluidity to ensure dimensionsfluctuation small and better strength.4.CIP： Using isostatic press, the defects are effectively stopped. Offering a good environment to get the blanks with uniform pressed density.5. Degumming and pre-burning semi-inspection processing6. HIP：The maximum sintering pressure can reach 100kg, eliminated the internal voids of alloy body effectively and get the high hardness andhigh strength carbide blank with good densification.7. Blank product inspection, processing
