5154 aluminium alloy

From Wikipedia, the free encyclopedia

5154 aluminium alloy is an alloy in the wrought aluminium-magnesium family (5000 or 5xxx series). As an aluminium-magnesium alloy, it combines moderate-to-high strength with excellent weldability. 5154 aluminium is commonly used in welded structures such as pressure vessels and ships. 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. It is generally not clad.

Alternate names and designations include AlMg3.5, N5, and A95154. The alloy 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 210: Standard Specification for Aluminum and Aluminum-Alloy Drawn Seamless Tubes

·         ASTM B 211: Standard Specification for Aluminum and Aluminum-Alloy Bar, Rod, and Wire

·         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
