INTRODUCTION

Aufhauser Aluminum 5654 was originally developed in 1968 to provide controlled low limits of manganese and copper. The result was a unique filler alloy that can be used to weld tanks for storage of hydrogen peroxide. This alloy contains more than 3% magnesium; therefore it is not recommended for elevated temperature applications due to its susceptibility to stress corrosion cracking.

 

APPLICATIONS

• Welding filler wire

 

GENERAL INFORMATION

• Non-Heat treatable
• Principle alloying elements: Magnesium, Chromium, Titanium
