Solid Bronze Ingots - CuSn7Zn4Pb7 Alloy

Solid bronze ingots (solid round bars) produced by centrifugal casting in CuSn7Zn4Pb7 alloy (Rg7, equivalent to UNI 7013 / EN 1982 CC493K). This leaded alloy is the most widely used for anti-friction applications thanks to its excellent combination of mechanical strength, wear resistance and the self-lubricating properties provided by the lead. Centrifugal casting ensures a homogeneous metallurgical structure, free from porosity and blowholes, with mechanical properties superior to static casting.

Technical specifications

  • Alloy: CuSn7Zn4Pb7 (Rg7 / CC493K)
  • Composition: Copper ~83%, Tin 7%, Zinc 4%, Lead 7%
  • Process: centrifugal casting (homogeneous structure, no porosity)
  • Type: solid round bar
  • Available diameters: 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 120 mm
  • Hardness: approx. 70-80 HB
  • Self-lubricating properties (lead in the alloy)

Applications and uses

  • Manufacture of bushes and plain bearings
  • Gears, worm screws and helical wheels
  • Anti-friction mechanical parts
  • Components for pumps, valves and fittings
  • Pins, sleeves and sliding guides
Note: The CuSn7Zn4Pb7 alloy complies with standard EN 1982 (CC493K). The lead in the alloy improves machinability on machine tools and anti-friction properties, making it ideal for bushes and plain bearings even in marginal lubrication conditions. Sold per kg, cut to size.
