5754 aluminium alloy
5754 aluminium–magnesium alloy is an alloy in the wrought aluminium -magnesium family. It is closely related to the alloys 5154 and 5454. Of the three 5x54 alloys, 5754 is the least alloyed, but only by a small amount. It is used in similar applications. As a wrought alloy, it can be formed by rolling, extrusion, and forging, but not casting. It can be cold worked to produce tempers with a higher strength but a lower ductility.
Alternate names and designations include, 3.3535, and A95754. The alloy and its various tempers are covered by the following standards:
- ASTM B 209: Standard Specification for Aluminium and Aluminium-Alloy Sheet and Plate
- EN 485-2: Aluminium and aluminium alloys. Sheet, strip and plate. Mechanical properties
- EN 573-3: Aluminium and aluminium alloys. Chemical composition and form of wrought products. Chemical composition and form of products
- EN 754-2: Aluminium and aluminium alloys. Cold drawn rod/bar and tube. Mechanical properties
- ISO 6361: Wrought Aluminium and Aluminium Alloy Sheets, Strips and Plates
