ECuMnNiAl (Nickel-Mang- Aluminum-Bronze)

Alloy Type:

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
