ATC302 Material Composition

ATCORP , ATC-302 Bimetal bearing material structure have steel backing and sliding layer of CuPb24Sn4 material.Steel Backing provides strength to Bimetal structure while soft Sliding layer of bronze helps to improve lubrication. Good resistance to fatigue strength and high load capacity, good performance of sliding.Alloy hardness 45-70 HRC.ATC-302 Material comes with three options like tin flash , copper flash or Zn Flashing also to avoid rusting of steel during transit /storage
