Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lower-strength alloys not heat-treatable
Only specific high-strength heat-treatable alloys per note 6 qualify for this breakout.
If made into doors, windows, or frames
Fabricated aluminum structures shift from raw bars to finished articles.
If for automotive body/chassis after processing
Vehicle parts classification depends on final assembly and end-use.
