Magnesium Alloy (Al-Mg). AA designation 5182.
Overview
Optimised for automotive body sheet and beverage-can ends, AA 5182 is an aluminium–magnesium alloy of 4.0–5.0% magnesium that blends high formability, moderate strength, and excellent surface quality. Suppression of the Portevin–Le Chatelier effect gives it lüders-band-free forming, and its corrosion resistance is strong. Its scored-opening performance has made it the dominant material for aluminium beverage-can ends.

説明
AA 5182 is an aluminum-magnesium alloy (4.0–5.0% Mg) specifically optimized for the automotive body sheet and beverage can end stock markets, providing a combination of high formability, moderate strength, and excellent surface quality. It exhibits Portevin-Le Chatelier (PLC) effect suppression important for lüders band-free forming, and outstanding resistance to corrosion. The alloy dominates production of aluminum beverage can ends (lids) due to its scored-opening performance.
