JF lead series

  • parameters

JF series materials, also known as bimetallic materials or copper lead steel strips, are made of low carbon steel or steel coil as the base material, and the surface is sintered with copper alloy steel and copper alloy products. Different copper alloy materials are suitable for different working conditions. The surface copper alloy grades can be divided into high lead series, lead series and lead-free series.
