Aluminum usage guidelines

The table on this page explains the characteristics of the different alloys types and what automobile
components they are used in.

Alloy designation
Characteristics Use in automobiles
AA UACJ

Excellent processability and surface treatability.
1050 A50 Heat insulators
The most corrosion-resistant of all aluminum alloys.
1000
Al 1100 A30 Heat insulators, license plates
