Acor Cu Sn A
Copper tin electrode
Description & applications
Basic coated electrode for welding of copper tin bronzes (Cu-Sn 6-8 %) and brasses (Cu-Zn) in some cases too. Also for dissimilar joints.
This electrode is especially designed to weld with alternative current. It is recommended for repairing wrought bronzes (Cu-Sn), for surfacing on brasses, steels and cast iron. Deposit is resistant to salt water corrosion.
Applications field: sea water applications, ship building, casting, armatures, propellers, shafts, bearings, pump rotors, valve seats, turbines, skates.
