C715 Copper Nickel Electrode


INTRODUCTION

Aufhauser Copper Nickel Electrode is a 70% copper - 30% nickel electrode that offers excellent resistance to the corrosive effects of salt water.

APPLICATIONS

  • Shielded metal arc welding (SMAW) of wrought or cast 70/30, 80/20 and 90/10 copper nickels to themselves or to each other
  • Welding clad side of copper-nickel clad steel
  • May also be used for joining copper-nickel Alloy 400, R-405 and K500 or high nickel Alloy 200 to the copper-nickel alloys

GENERAL INFORMATION

Chemical Composition
Copper Manganese Iron Silicon Nickel Phosphorus Titanium Other*
Remainder 1.0-2.5 0.40-0.75 0.50 29-33 0.02 0.50 0.50

Note: Copper contains Silver; Nickel contains Cobalt. All values are maximum percentage, unless shown in range. * Total Other includes 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.
