Automotive fuel tanks, trailer body panels, pressure vessels, ship sheet metal, and outdoor corrosion-resistant structural components.
5082 is an Al-Mg corrosion-resistant alloy with higher strength than 5052 and outstanding corrosion resistance and weldability. It suits stamping and sheet metal parts that need good corrosion resistance.
It cannot be strengthened by heat treatment, so there is no T651 temper. Its strength comes from its composition and work hardening, and welded joints perform consistently.
It is mostly used for storage and transport containers, vehicle panels, trailer body panels, automotive fuel tanks, pressure vessels, marine sheet metal and outdoor corrosion-resistant structures. It is not recommended for linear module bases or other load-bearing substrates that need heavy-allowance milling and long-term micron-level accuracy.
