Gunmetal round tubes 61 x 19 mm CC493K
Product information
Gunmetal round tubes – CuSn7Zn4Pb7-C (RG7) / CC493K
Gunmetal round tubes 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 ideal for the production of bushings, bearings and 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
