Acor Cu Sn A

Coated electrode for bronze welding

Product description

Basic-coated electrode for welding bronzes (copper-tin 6-8%), brasses (copper-zinc) and similar alloys.

This electrode is particularly suitable for welding in alternating current, but also in direct current + and -. Also recommended for repairing bronze castings, for plating brass and brass alloys, and for plating ordinary steels and cast irons. Excellent corrosion resistance.

Applications: Marine industry, foundries, steelworks, armatures: propellers, shafts, bearings, slides, pump rotors, valve seats, propeller shaft sleeves, turbines, skids, repair of galvanized assemblies, etc.
