ECuMnNiAl (Nickel-Mang- Aluminum-Bronze)
Alloy Type: A5.6, COPPER AND COPPER ALLOY Covered Arc Welding Electrodes
ECuMnNiAl (Nickel Manganese Aluminum Bronze) is a universal copper based welding electrode which safely repairs all grades of aluminum bronzes. It has a very high strength and provides excellent wear resistance. This electrode resists corrosion, cavitation, erosion, and metal-metal wear. Preheat is not required when welding this electrode. Clean slag thoroughly between passes.
Typical Applications: joining and surfacing parts subject to service in marine/seawater environments
