  • MIG and TIG welding of cast and wrought nickel-aluminum bronze parts where high resistance to corrosion, erosion, and cavitation in salt or brackish water is required
  • Joining and repairing of cast or wrought nickel-aluminum bronze base metals

GENERAL INFORMATION

Chemical Composition
Copper Zinc Manganese Iron Silicon Nickel Aluminum Others
Remainder 0.10 0.60-3.50 3.0-5.0 0.10 4.0-5.50 8.50-9.50 0.50

Note: Copper contains silver; Nickel includes Cobalt. All values are maximum percentage, unless shown in range.

ADDITIONAL INFORMATION

Copper and its alloys require a relatively high heat input with shortened welding time. Higher preheat temperatures and faster welding rates than for steel are necessary.
