Mechanical Properties of Typical Aluminum Alloys

For automobile components, the most suitable aluminum alloy is selected according to the part to be used and the required properties, such as strength, workability, corrosion resistance, and surface treatment. Aluminum alloys are made by adding elements or combining tempering to change their properties through heat treatment or machining.
