| Composition: |
Al 4.5Mg 0.3Mn |
| Applications: |
Packaging: container ends, can stock. Motor vehicles: automotive body panels and reinforcement members, brackets and parts. |
| Characteristic Properties: |
5000 series alloys include Al-Mg and Al-Mg-Mn types. They are in the main stronger than 3000 series and have good corrosion resistance and weldability combined with formability. They are mainly used in sheet or plate form but can be obtained as extrusions, albeit which much less flexibility of shape than 6000 series alloys. 5182 alloy was designed for manufacturing of beverage can easy-opening ends which require maximum strength to ensure minimum thickness and lowest cost. It is also used for formed parts in automotive bodies but stretcher-strain marks which can occur on forming mean that it is restricted to inner panels, brackets and supports which are not visible in the final structure. Its use for can ends is perhaps the best example of the way in which a high strength low ductility material can be formed in a complex and demanding manner provided the correct precautions are observed with respect to tool design, lubrication and metal surface conditions. |
| Precautions and Warnings: |
Subject to stretcher strain marks. |
