INTRODUCTION
Aufhauser Aluminum Bronze A-1 Electrode is designed for joining and surfacing on aluminum bronzes with up to 10% Al and for dissimilar joints between steels and CuAl-bronzes. Aluminum Bronze A-1 produces strong, dense, ductile, and crack-free weld deposits that will work-harden under compression. Possesses excellent weldability, stable arc, less spatters; easy to remove slag.
APPLICATIONS
- Joining aluminum bronzes of similar composition, high strength copper-zinc alloys, silicon bronzes, manganese bronzes, some nickel alloys, many ferrous metals and alloys, and combinations of dissimilar metals
- Overlaying cast iron, steels and copper alloys
- Ship building, seawater applications, desalination plants, chemical industry, pump parts which are attacked by salt water (propellers, bearings, etc.)
- Surfacing wear- and corrosion-resistant bearing surfaces
GENERAL INFORMATION
Chemical Composition| Copper | Aluminum | Manganese | Zinc | Silicon | Lead |
|---|---|---|---|---|---|
| Remainder | 6.0 - 9.0 | 0.50* | 0.20* | 0.10* | 0.02* |

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.
