It deposits nickel aluminum bronze and is suitable for welding wrought and cast parent materials of similar composition. These alloys have high strength and resistance to stress corrosion, cavitation erosion, corrosion fatigue, and attack by acids and chlorides. Applications include corrosion resistant and spark resistant pumps, ship propellers, heat exchangers for offshore, marine and mining equipment. For aluminum bronze alloys preheat is not required and maximum interpass temperature should be 150°C. Resistance to hot cracking in thick sections with high restraint is said to be inferior to plain aluminum bronze. An alternative is to fill with CuAl higher ductility aluminum bronze and cap with CuAlNi.
