Understand the characteristics and advantages of precision tungsten steel bushing


  Carbide bushings, also known as tungsten steel bushings, are made of refractory metal hard compounds and bonded metal through powder metallurgy made of an alloy material. Tungsten steel bushing is mainly used for stamping, with wear-resistant, impact resistance characteristics.
  The main material Carbide has a high hardness, wear resistance, strength and toughness is good, heat, corrosion and a series of excellent performance, especially its high hardness and wear resistance, even at 500 ℃ temperature is also basically maintained Unchanged, at 1000 ℃ still have a high hardness.
  1, the use of advanced molding technology, you can produce a variety of complex shapes of cemented carbide products.
  2, deformation is small, very high accuracy.
  3, no need for machining or only a small amount of processing.
  Hunan tungsten resources reserves ranks first in the country, tungsten and carbide products accounted for more than 6 percent of the country. At present, the scale of domestic tungsten-based materials is micron-level, if down to the nanometer level, the performance will be significant changes, with high hardness and high toughness, China's priority development of strategic emerging materials.
  Good concentricity, good verticality, high wear resistance and high toughness. Greatly improve the service life of the mold, reducing the use of mold production costs.
  Use CNC precision angle and bore grinder, NC angle and bore grinding and polishing machine, precision surface grinder, precision internal and external grinder, centerless grinder. , The hole through a number of grinding and polishing into a mirror.
