DESCRIPTION
ERCuNiAl is copper based type material designed for welding of cast and wrought, nickel-aluminium-bronze. Characterized by high mechanical strength, resistance to seawater, wear, abrasion, cavitation and erosion.
The most popular application is for repair and maintenance of ship ttings and propellers. Can also be used in offshore technology for such applications involving sea-water descaling planets, ship building and repair, power and chemical plant pumps and tube systems.
