C624 Aluminum Bronze A-3
Nominal Chemical
Composition
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 CompositionCopper | Aluminum | Iron | Manganese | Silicon | Tin |
---|---|---|---|---|---|
Remainder | 10.0 - 11.5 | 2.0 - 4.5 | 0.30* | 0.25* | 0.20* |
* Max (Other)
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.
