C633 Manganese Nickel Aluminum Bronze Electrode


INTRODUCTION

Aufhauser EC633 - Manganese Nickel Aluminum Bronze Electrode - is a basic coated manganese bronze electrode (Cu Mn Al Fe) for welding and surfacing of aluminum bronzes and for dissimilar joints between steels and copper alloys. It is also recommended for overlays on cast iron, steels and copper alloys. Excellent welding characteristics, stable arc, low spatters, very easy slag removal. Low anti-friction properties of the deposit make EC633 an excellent choice for overlaying on sliding guides.

APPLICATIONS

  • Joining or repairing cast or wrought manganese-nickel-aluminum bronze materials
  • Naval constructions, sea water applications and chemical industry (pumps, propellers, etc.)

GENERAL INFORMATION

Remainder 11.0-13.0 2.0-6.0 1.50 1.0-2.5 5.0-7.5 0.50

* 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.
