C624 Aluminum Bronze A-3


INTRODUCTION

Aufhauser Aluminum Bronze A-3 contains a higher iron content than the C618 (Aluminum Bronze A-2). The higher iron content gives "A-3" greater strength, while maintaining good ductility.

APPLICATIONS

  • Overlaying pistons and depositing bearing surface applications.
  • Joining Aluminum Bronze castings of similar composition.

GENERAL INFORMATION

Chemical Composition
Copper Aluminum Iron Lead Silicon Zinc
Remainder 10.0-11.5 2.0-4.5 0.30 0.25 0.20

Note: Copper contains Silver

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.
