ATC305 Material Composition

ATCORP, ATC-305 Bimetal bearing material is a sliding bushing with steel Backing and a CuPb30 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 speeds and low loads, such as combustion engines, air compressors and refrigerators.Steel Backing provides strength to Bimetal structure while soft Sliding layer of AlSn20Cu helps to improve lubrication. ATC 305 has medium fatigue strength and load-bearing capacity, good corrosion resistance, better sliding properties, and other characteristics. Can be set in oil holes, grease indents or oil pockets.ATC-305 Material comes with three options like tin flash, copper flash or Zn Flashing also to avoid rusting of steel during transit /storage

Benefits of ATC305

  • medium fatigue strength and load-bearing capacity, good corrosion resistance, better sliding properties
  • This characteristic helps reduce friction and minimize wear between moving parts, translating into a longer lifespan for the bushing and reduced downtime
  • Widely used in internal combustion engine, connecting rod bushing.
  • Can we machined to achieve tighter tolerances up to certain thickness
