Project Description

W-12

EN 1982 CC483K
CuSn12-C
  • The W-12 is a bronze with 12% tin.
  • The closest international standards are the ASTM B505 C90700 and DIN 1705 CuSn12
  • Hard and tough material. High resistance to corrosion, impacts and cavitation. Good performance with high loads and pressures.
  • Wisco has a large stock of rectangular bars and round solid and hollow bars with immediate availability.
