Description and Applications

  • Corrosion- and seawater-resistant alloy with very good glide properties (metal-metal). A 215/8 W is very easy to handle and ensures a perfect weld in the root pass and a clean top surface. The seam is smooth and non-porous. Joint and build-up welding on aluminum-bronze, high-strength brass, steel and cast iron. For use in the machine-, chemical- as well as shipbuilding industries. Joint welding: Corrosion-resistant aluminum-bronze or high strength brass pipe work. Joining of copper conduits with steel. Preheat thick workpieces to 200°C. Build-up welding: Building-up of ship propellers, kid rails, running surfaces, bearings, valves, slide gates, fittings, etc.
