Product information

Gunmetal round bars – CuSn7Zn4Pb7-C (RG7) / CC493K

Gunmetal round bars made of CuSn7Zn4Pb7-C (RG7), also known as CC493K, are high-quality bearing materials with excellent emergency running properties and high wear resistance. They are ideally suited for applications with high mechanical loads as well as for use in corrosive environments, including seawater.

Main features

  • Material: CuSn7Zn4Pb7-C (RG7)
  • Material number: CC493K
  • Standard: EN 1982:2008
  • Surface: continuous cast, raw
  • Profile shape: round bar

Note: Saw-cut edges are unfinished and not deburred. Continuous cast surfaces show typical material-related irregularities and are not comparable to drawn or rolled surfaces.

Material properties

  • very good machinability
  • high corrosion resistance, including seawater resistance
  • excellent sliding and emergency running properties
  • high wear resistance
  • resistant to cavitation

Technical specifications

  • Material: CuSn7Zn4Pb7-C (RG7)
  • Material number: CC493K
  • Standard: EN 1982:2008
  • Surface: continuous cast, raw
  • Manufacturing process: continuous casting

Dimensional tolerances

  • Outer diameter: -0 / +0.6 mm

Production-related deviations within the applicable standards are permitted.

Applications

  • plain bearings and bushings
  • bearing shells
  • gears and transmission components
  • fittings and valves
  • hydraulic systems
