Acor Cu Sn C
Copper tin electrode for DC
Description & applications
Basic coated electrode for welding copper tin bronzes (Cu-Sn 6-8%) and brasses (Cu-Zn) in some cases too. Also used for dissimilar joints. Cu115 electrode is recommended for repairing wrought bronzes (Cu-Sn), for surfacing on brasses, steels and cast iron. The deposit is resistant to salt water corrosion.
Main applications: Construction of equipment for the chemical industry and petrochemical industry, naval constructions and installations for sea water desalination, repair works.
