Aluminium Alloy
Aluminum alloy is a material composed of aluminum and other metal elements
with light weight, high strength characteristics, widely used in industrial and manufacturing fields.
GMW15192
It is applicable to two types of wrought aluminum alloys; age hardenable and non-age hardenable. Age hardenable (e.g., 6000 series) aluminum alloys can be used for exposed and unexposed applications. Due to surface characteristics, non-age hardenable (e.g., 5000 series) alloys may not be suitable for exposed applications.
Material: 5000 Series / 6000 Series
Application: Typical applications include body and closure panel applications such as hoods, doors, fenders, liftgates, body sides, roofs, and underbody components.

Note 1: Chemical composition shall be determined per ASTM E34, ASTM E101, ASTM E607, ASTM E1251, or DIN EN 14726. In cases of dispute, referee method shall be ASTM E34.
Note 2: Chemical composition based on product (coil or sheet/blank) analysis.
Note 3: Although the specified ranges for Silicon, Magnesium, Manganese, and Copper are wide, it is required that each supplier will use process control to maintain the composition to within a 0.4 range for these elements for production material.
