ATCORP, ATC-304 Bimetal bearing material is a sliding bushing with a tin and aluminium base, a steel strip and a AISn20Cu 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 304 has medium fatigue strength and load-bearing capacity, good corrosion resistance, better sliding properties, and other characteristics. This product is commonly used as shaft tiles for small and medium power internal combustion engines, train engine shaft tiles, and air press bushings, and is a novel product to replace the pasteurized alloy.Can be set in oil holes, grease indents or oil pockets.ATC-304 Material comes with three options like tin flash, copper flash or Zn Flashing also to avoid rusting of steel during transit /storage

Benefits of ATC304
Medium fatigue strength and load-bearing capacity, good corrosion resistance, better sliding properties.
Helps reduce friction and minimize wear between moving parts, resulting in a longer lifespan for the bushing and reduced downtime.
Widely used in automotive applications such as compressors, steering gear, power steering, pedal bearings, king-pin bushes, etc.
Leaded tin bronze alloys are generally known for their good machinability, simplifying manufacturing and customization processes.
Can be machined to achieve tighter tolerances up to certain thickness.
