Aluminum Alloy 5083
Types: Aluminum 5083-H321, UNS A95083, ISO AlMg4.5Mn, Aluminum 5083-H116, AA5083-H116
Aluminum 5083 is a highly versatile non-heat-treatable alloy known for its exceptional strength and corrosion resistance. It performs exceptionally well in harsh environments such as marine and industrial settings. While it offers the highest strength among non-heat-treatable aluminum alloys, it is not recommended for use above 65°C due to potential loss of mechanical properties at higher temperatures.
This alloy is also praised for its excellent weldability, which allows it to maintain its structural integrity after welding. It combines good ductility with strong formability, making it suitable for a wide range of applications, including cryogenic services where low-temperature performance is critical.
