C610 Aluminum Bronze A-1


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 brakish water and commonly used acids.
  • Overlaying tube sheets, valve seats and refineries in steel and pulp mills.

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.
