C632 Nickel Aluminum Bronze Electrode


INTRODUCTION

Aufhauser Nickel Aluminum Bronze Electrodes were developed for the welding of cast and wrought nickel aluminum bronze applications requiring high resistance to corrosion, erosion, or cavitations in salt and brackish water. The slag is easy to remove and the weld beads are regular.

APPLICATIONS

  • Ship fittings, Ni-Br-Al boat propellers, power plant valves, piping systems, intake screens
  • Oil recovery pumps propeller gear housings

GENERAL INFORMATION

Chemical Composition
Copper Manganese Iron Silicon Nickel Aluminum Other*
Remainder 0.50-3.50 3.0-6.0 1.50 4.0-6.0 6.0-8.5 0.50

Note: Copper contains Silver. All values are maximum percentage, unless shown in range. * Total Other elements include Zinc, Tin = 0.50%

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.
