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
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.
