Aluminum alloy 5083 is a highly versatile and widely used material known for its exceptional strength, excellent corrosion resistance, and weldability. Composed primarily of aluminum, with minor additions of magnesium and traces of manganese, this alloy finds significant applications in maritime and naval industries due to its outstanding resistance to seawater and other harsh environments. Its high tensile strength makes it suitable for various structural components, such as shipbuilding, offshore structures, and pressure vessels. Moreover, 5083 aluminum alloy’s favorable combination of properties, including formability and low-temperature capabilities, extends its usefulness to various transportation and automotive applications. As a result, this alloy stands as a reliable choice for a wide range of engineering and industrial requirements.

Characteristics

Medium strength alloy, fair workability, excellent weldability and corrosion resistance.

Chemical

This table contains the chemical composition limits of wrought aluminum alloys in percent by weight maximum unless shown as a range or minimum. Except for “aluminum” and “others, ” analysis normally is made for elements for which specific limits are shown. For purposes of determining conformance to these limits, an observed value or a calculated value obtained from analysis is rounded off to the nearest unit in the last right-hand place of figures used in expressing the specified limit, in accordance with ASTM Recommended Practice E29.

(1) Includes listed elements for which no specific limit is shown.
(2) A .0008 weight percent maximum beryllium is applicable to any alloy to be used as welding electrode or welding rod.
(3) The sum of those “others” metallic elements 0.010 percent or more each, expressed to the second decimal before determining the sum.
(4) The aluminum content for unalloyed aluminum not made by a refining process is the difference between 100.00 percent and the sum of all other metallic elements present in amounts of 0.010 percent or more each, expressed to the second decimal before determining the sum.
(5) Beryllium 0.0008 maximum for welding electrode and welding rod only.
(6) Also contains 0.20 to 0.6 percent each of lead and bismuth.
(9) Boron 0.06 percent maximum.
(10) Also contains 0.40 to 0.7 percent each of lead and bismuth.
(12) Also contains 0.08 to 0.15 percent of zirconium.
