Aluminum 5356
Nominal Chemical
Composition
INTRODUCTION
Aufhauser Aluminum 5356 is the most widely used welding alloy and can be classified as a general purpose type filler alloy. AL5356 is typically chosen because of its relatively high shear strength. The 5XXX alloy base material, welded with AL5356, possessing a weld pool chemistry greater than 3% magnesium and service temperatures in excess of 150°F will be susceptible to stress corrosion cracking.
APPLICATIONS
- Welding filler wire
- Nail wire
- Recommended for joining 5050, 5052, 5083, 5086, 5356, 5454, and 5456
GENERAL INFORMATION
- Non-Heat treatable
- Principle alloying elements: Magnesium
- Moderate high strength capabilities
- Bright finish
- ISO designation: AIMg5Cr(A)
