Powder metallurgy parts are widely used in automobile, toys, tools, household appliances and general machinery. They include two large categories, mechanical parts and oil-retaining bearing. The advantages of powder metallurgy parts: Full automatic mass production with much lower cost; Using for a long time without oil feed; Applicable to low and high speed, possessing good quality in lubrication and antifriction; Precise measurement and fine surface; Steady rotating with no noise; Long mechanical service life. Materials: Fe, Cu Alloy Fe. Yankees FN, Fasten (SMF) CuSn10 FLN or Copper Tin, SUS (303,304) Stainless Steel, etc. Weight: from 0.01 gram to 500 grams.
