Range of application

bercoweld A822

The multi alloy copper- aluminum based welding filler metal is particularly suitable for CuAlNi alloyed metals. Joining of steel and CuAl- alloys. High resistance to wear and abraison. Very good corrosion resistance to seawater. Preheating is recommended for large work pieces. As first layer for surface welding on ferrous products, impulsed arc welding is recommended.
