5454 aluminium alloy

5454 aluminium alloy is an alloy in the wrought aluminium-magnesium family (5000 or 5xxx series). It is closely related to 5154 aluminium alloy. As an aluminium-magnesium alloy, it combines moderate-to-high strength with excellent weldability. Like 5154, 5454 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 (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.[1]

Alternate names and designations include 3.3537, N51, and A95454. The alloy and its various tempers are covered by the following standards:[2]

  • 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

gollark: How powerful's your server, anyway?
gollark: I bet it's a layer 8 error.
gollark: Cool idea: I found out that you can send messages via open stargate connections, so you could have computers on each end controlling the stargate irises and verifying that the other end is who they're meant to be through some sort of public key crypto scheme.
gollark: Meh.
gollark: I'm using FTBUtils.
