Tungsten carbide bushings are primarily made from tungsten carbide powder and refractory metal powders such as cobalt and nickel. The process involves material formulation, wet grinding, drying, pressing, sintering, and finally machining. The choice of materials and manufacturing process characteristics allow tungsten carbide bushings to operate efficiently in high-temperature, high-pressure, and highly corrosive environments, offering excellent wear resistance and long service life. Consequently, tungsten carbide bushings replace steel and other materials in various mechanical sliding parts, such as automated machinery (extension, swing, sliding, bending, rotary, revolving parts), oil cylinder guide sleeves, submersible pump motors, centrifugal pumps, textile machinery, plastic molding machines, die casting machines, rubber machinery, food machinery, fitness equipment, office machinery, hydraulic handling vehicles, automotive, motorcycles, agricultural and forestry machinery, etc.
1.Using high-quality virgin tungsten carbide materials.
2.Unlike conventional pressing and sintering ways, our carbide bushings are produced by advanced forming processes such as cold isostatic pressing and overpressure sintering, which makes them in superior product performance.
3.We can produce various complex shapes of non-standard tungsten carbide products based on customer's samples or drawings, ensuring stable performance and reliable quality.
4.Unique quality control during production and stringent final product inspection requirements effectively control internal stress in shaped products, preventing cracking during wire cutting and eliminating defects such as pores and cracks.
5.Non-destructive ultrasonic flaw detection ensures no sand holes or pores.
6.High material density, high strength, impact resistance, corrosion resistance, excellent wear resistance, and long service life for our carbide sleeves.
7.Main grades available for tungsten carbide bushings include YG6, YG8, YG11, YG15, YN8, YN9, YN11, etc.
