ATC306 Material Composition

ATCORP, ATC-306 Bimetal bearing material is a sliding bushing with steel Backing and a CuSn6Zn6Pb3 surface sliding layer.These bushings are characterised by their long services lives, low levels of material fatigue, high levels of resilience and low susceptibility to corrosion.These sliding bushings are used in applications with high Loads and low speeds , such as King Pins, Balance Beam , steering knuckle , centre pivot of vehicle and many other heavily loaded applications.Steel Backing provides strength to Bimetal structure while soft Sliding layer of CuSn6Zn6Pb3 helps to improve lubrication with strong wear resistant properties.Can be set in oil holes, grease indents or oil pockets.ATC-306 Material comes with three options like tin flash, copper flash or Zn Flashing also to avoid rusting of steel during transit /storage

Benefits of ATC306

  • The steel backing provides exceptional mechanical strength and rigidity, enabling the bushing to withstand significant static and dynamic loads without deformation or failure.
  • CuSn6Zn6Pb3 is a bronze alloy known for its high wear resistance, further enhanced by the presence of tin. This wear-resistant sliding layer ensures a prolonged service life for the bush, even under continuous motion and friction, reducing the need for frequent replacements and minimizing downtime.
  • CuSn6Zn6Pb3 bronze exhibits excellent resistance to corrosion in various environments, including seawater and industrial atmospheres.
  • The bronze layer, metallurgically bonded to the steel, efficiently draws heat away from the sliding surface, preventing overheating, especially under high load/speed conditions. This enhanced thermal conductivity contributes to stable performance and longer lifespan.
  • The lead content in the CuSn6Zn6Pb3 alloy improves its machinability, simplifying fabrication and potentially reducing manufacturing costs.
