Al-2024. This paper investigated the effect of heat treatment on mechanical properties and microstructure of 6061 aluminium alloy. Its composition, chemical properties, mechanical properties, physical properties, corrosion resistance, heat resistance and heat treatment are all important factors to consider when selecting aluminium.

General 2024 characteristics and uses (from alcoa): The main alloying addition is copper, and it is formulated for primary forming into wrought products.
