Aluminum 5083
Material Data Sheet
Aluminum 5083 is a non-heat treatable alloy known for its resistance to extreme environments, including seawater corrosion and industrial chemicals. While featuring limited machinability due to its exceptional strength, Al-5083 is the material of choice for marine and aquatic applications and is typically used in shipbuilding. Other uses for this alloy include transportation applications such as rail, truck, and vehicle bodies, as well as pressure vessels and food processors.
5083 Aluminum is alloyed with magnesium and traces of manganese and chromium. Alloy 5083 retains exceptional strength after welding. It has the highest strength of the non-heat-treatable alloys but is not recommended for use in temperatures in excess of 65°C.
