Product information

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

Gunmetal square bars made of CuSn7Zn4Pb7-C (RG7), also known as CC493K, are proven bearing materials with excellent emergency running properties and high wear resistance. Thanks to their stable square shape, they are ideal for highly stressed components as well as for applications in corrosive environments, including seawater.

Main features

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

Note: Saw-cut edges are unfinished and not deburred. Continuous cast surfaces show typical material-related irregularities as well as rough structures 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

  • Width / height: -0 / +1 mm

Production-related deviations within the applicable standards are permitted.

Applications

  • plain bearings and bearing plates
  • bearing shells and wear plates
  • gears and machine parts
  • fittings and valves
  • hydraulic systems
  • highly stressed structural components

Surface condition and appearance may vary depending on the batch. Deviations between the product presentation and the actual delivery are possible due to different production batches as well as display-related screen deviations and do not constitute grounds for complaint.
