Definitions

  • the invention relates to a copper zinc alloy, which is employable for sliding bearings.
  • the material must possess a low friction coefficient in order to avoid “jamming” and a high wear resistance in order to obtain a long service life.
  • copper zinc alloys of the type CuZn31Si1.
  • the properties of the CuZn31Si1 alloys no longer meet the requirements that are imposed on materials for sliding bearings in modern engines, for instance, diesel engines.
  • the operating temperature of the sliding bearings may reach and exceed 300° C.
  • the employed copper zinc alloys however, soften at temperatures around 250° C. Consequently, sliding bearings made of this alloy no longer have the requisite strength at the operating temperature.
  • the invention is therefore based on the problem of providing a copper zinc alloy for use as a material for sliding bearings, wherein the copper zinc alloy meets the requirements imposed on a material for sliding bearings, in particular at elevated temperatures, and can also be easily produced.
  • the object is achieved according to the invention by the use of a copper zinc alloy as a material for sliding bearings wherein the alloy comprises 59-73% copper, 2.7-8.5% manganese, 1.5-6.3% aluminum, 0.2-4% silicon, 0.2-3% iron, 0-2% lead, 0-2% nickel, 0-0.4% tin, residual zinc and unavoidable impurities.
  • a novel use for a copper zinc alloy is therefore specified.
  • a similar alloy according to DE 29 19 478 C2 is used as a synchronizing ring alloy and is known to those skilled in the art because of this field of use as an alloy, which has a high friction coefficient in combination with the other intrinsic material properties.
  • a high friction coefficient is disadvantageous for the use of a material as a sliding bearing, since a high friction coefficient describes a strong interaction between the sliding bearing and its surroundings and is also expressed by a great tendency to jam during the sliding operation.
