uniform tissue high collapsing strenght high oil contain good abrasion resistance floating press and inhalation feed

  Valve guide made of powder metallurgy in our company has a 120mm long and the ratio of the length and diameter is 6:1. Because the product adopts suction method to charge material, floating press and five-zone continuous sintering furnace, it has uniform tissue, little density variety, high collapsing strength, high oil containing, better self-lubrication and good abrasion resistance. Our products can be widely used  in 1------1000kw internal combustion engine.
