Aluminum 5086-O
Categories:	Metal; Nonferrous Metal; Aluminum Alloy; 5000 Series Aluminum Alloy
Material Notes:	This alloy has very good corrosion resistance (susceptible to deterioration after prolonged exposure to elevated temperatures) and moderate strength. Its weldability is a plus. It is used similarly to aluminum 5083 (although 5086 has better stress corrosion cracking resistance) - in transportation, pressure vessels, cryogenics, towers and drilling rigs, gas/oil piping, ordnance, and armor plate. Data points with the AA note have been provided by the Aluminum Association, Inc. and are NOT FOR DESIGN. Composition Notes: Composition information provided by the Aluminum Association and is not for design.
Key Words:	UNS A95086; ISO AlMg4; Aluminium 5086-O; AA5086-O; Al5086-O
