5454 aluminium alloy sheet

addtiame:2017/01/17 click:
5454 aluminium alloy sheet is an alloy in the wrought aluminium-magnesium family (5000 or 5xxx series). It is closely related to 5154 aluminium alloy sheet .  As an aluminium-magnesium alloy sheet , it combines moderate-to-high strength with excellent weldability. Like 5154, 5454 aluminium sheet  is commonly used in welded structures such as pressure vessels and ships. As a wrought alloy sheet , it can be formed by rolling, extrusion, and forging (although forging is not common), but not casting. It can be cold worked to produce tempers with a higher strength but a lower ductility. It is generally not clad

Alternate names and designations include 3.3537, N51, and A95454. The alloy sheet  and its various tempers are covered by the following standards:

    ASTM B 209: Standard Specification for Aluminum and Aluminum-Alloy Sheet and Plate
    ASTM B 221: Standard Specification for Aluminum and Aluminum-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes
    ASTM B 547: Standard Specification for Aluminum and Aluminum-Alloy Formed and Arc-Welded Round Tube
    ISO 6361: Wrought Aluminium and Aluminium Alloy Sheets, Strips and Plates
