5 Series Overview
5 Series Overview is a typical non‑heat‑treatable aluminum‑magnesium alloy, whose strength is enhanced mainly by magnesium element addition.
It features good corrosion resistance, outstanding weldability and ductility, and can be easily formed and processed. Mainly used in industries such as transportation, shipbuilding, construction and electronic equipment.
Excellent Corrosion Resistance
High rust resistance for humid and outdoor environments.
Superior Weldability
Stable welding performance with good weld‑joint toughness for component assembly.
High Ductility & Formability
Good stretchability for bending and stamping of complex‑shaped parts.
