C610 Aluminum Bronze A-1
Nominal Chemical
Composition
INTRODUCTION
Aufhauser Aluminum Bronze A-1 is an iron-free aluminum bronze filler metal used for MIG and TIG overlay welding. Aluminum Bronze A-1 is not recommended for joining.
APPLICATIONS
- MIG and TIG overlay welding of wear resistant surfaces exposed to corrosive environments such as salt or brackish water and commonly used acids.
- Overlaying tube sheets, valve seats and refineries in steel and pulp mills.
GENERAL INFORMATION
Chemical Composition| Copper | Aluminum | Manganese | Zinc | Silicon | Lead |
|---|---|---|---|---|---|
| Remainder | 6.0 - 8.5 | 0.50* | 0.20* | 0.10* | 0.02* |
* 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.
