8079 Aluminum Disk

8079 Aluminum Disk is an iron-modified aluminum alloy in precision circular geometry, available in Soft Annealed and Hard tempers, providing well-characterized specimens suited to formability evaluation, surface science, and barrier coating studies. The Soft Annealed condition gives maximum ductility for forming characterization; the Hard temper allows direct study of the cold-form packaging condition in a defined geometry. In industry, disk specimens are used for incoming quality control of formability and mechanical consistency in pharmaceutical and flexible packaging foil supply chains. In research, 8079 disks serve as standardised specimens for Erichsen cupping tests and limiting drawing ratio determinations, comparative studies of Soft Annealed versus Hard temper forming behavior relevant to cold-form blister packaging, electrochemical corrosion and surface passivation studies, and barrier coating adhesion trials where the 8079 composition provides a direct analogue to the industrial packaging substrate. The defined circular geometry simplifies fixture design and enables systematic comparison across temper conditions.
