- Other industrial applications
Description:
7021 aluminum is a 7000-series aluminum alloy: the main alloying addition is zinc and it’s formulated for primary forming into wrought products. Cited properties are appropriate for T6 temper. AA7021 is Aluminum Association (AA) designated. In European standards, it will be given as EN AW-7021. It fills a gap between medium and high resistance alloys, the latter being in many cases undervalued. It is characterized by a very low microporous homogeneous structure, excellent machinability and high resistance.
