bercoweld® A35
bercoweld® A35 is used for welding cast and forge parts made of nickel-aluminum-bronze in shipbuilding (ship propellers, etc.), parts for power stations including valves, sieves, pumps, pipe systems, as well as for apparatus engineering and food containers. Buildup welding on steel and AlBz, including multi-material alloys. The weld metal is resistant to seawater and corrosion and is also resistant to wear (for example, simultaneous exposure to seawater, cavitation, and erosion).
