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

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.
