C633 Manganese Nickel Aluminum Bronze


INTRODUCTION

Aufhauser Manganese Nickel Aluminum Bronze filler metal is especially suited for welding ship propellers where resistance to corrosion, erosion and cavitations is required. Good toughness and hardness.

APPLICATIONS

  • MIG and TIG welding or surfacing of cast or wrought base metals of similar composition.
  • Joining or surfacing copper alloys of unalloyed and low alloy steel as well as gray cast iron subject to corrosion.

GENERAL INFORMATION

Chemical Composition
Copper Zinc Manganese Iron Silicon Nickel Aluminum Others
Remainder 0.15* 11.0-14.0 2.0-4.0 0.10* 1.5-3.0 7.0-8.5 0.50*

* Max. 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.
