Definitions

  • the brass alloy according to the invention contains: 59 to 62% by weight Cu, 2.0 to 2.5% by weight Mn, 0.5 to 1.5% by weight Si, less than 0.1% by weight Pb, the balance Zn and unavoidable contamination.
  • composition of the lead-free brass alloy according to the invention is particularly preferred: 61.2% by weight Cu, 2.3% by weight Mn, 0.8% by weight Si, 0.07% by weight Fe, 0.07% by weight Sn , less than 0.1% by weight of Pb, the balance of Zn and unavoidable impurities.
  • the lead-free brass alloy according to the invention preferably contains less than 0.2% by weight of Ni, preferably 0.02% by weight to less than 0.2% by weight of Ni.
  • a preferred embodiment of the invention provides that the lead-free brass alloy contains less than 0.1% by weight of Al, preferably 0.01% by weight to less than 0.1% by weight of Al.
  • the invention relates to a bearing element or a bushing which is made from the lead-free brass alloy according to the invention. Because of your Due to its good friction properties, the lead-free brass alloy is ideal for the production of bearing elements and bushings.
  • Fig. 3 shows a chip image produced by machining a lead-free brass alloy according to the invention.
