Leaded Bronze Ingots
Leaded Bronze are high-leaded tin bronze alloys with lead content ranging between 7 - 30 percent. This group of alloys is free cutting and retains good thermal conductivity and good lubricity due to the presence of lead. High-leaded tin bronzes are ideal for bearing applications where there could be a loss of the lubrication boundary. The addition of nickel in these alloys enhances the strength and ductility.
Bright Metals is a trusted manufacturer and supplier of high-quality Leaded Bronze ingots. With advanced technology and strict adherence to quality norms, we produce homogenous Leaded Bronze alloys that meet customer specifications. We take immense pride in our ability to deliver copper-based Leaded Bronze alloy ingots that meet the highest industry standards and strictest quality norms. Our superior quality Leaded Bronze ingots result in brilliant castings and significantly reduce rejections.
TYPICAL USAGE: Pump Bodies, Applications requiring acid resistance to sulphite fluids, bearing plates, bearings, bushings, bushings for high speed and heavy pressure, corrosion-resistant castings, crank shafts, high speed/heavy load bearings, impellers, machine parts, parts for steel mill maintenance, pressure-tight castings, pumps, slide guides for steel mills, hardware brackets, nuts, washers for engines, large bearings for ships etc.
