8079 Aluminium Disc

8079 Aluminium Disc is an iron-modified aluminium alloy in precision circular geometry, available in Soft Annealed and Hard tempers, providing well-characterised specimens suited to formability evaluation, surface science, and barrier coating studies. The Soft Annealed condition gives maximum ductility for forming characterisation; the Hard temper allows direct study of the cold-form packaging condition in a defined geometry. In industry, disc specimens are used for incoming quality control of formability and mechanical consistency in pharmaceutical and flexible packaging foil supply chains. In research, 8079 discs serve as standardised specimens for Erichsen cupping tests and limiting drawing ratio determinations, comparative studies of Soft Annealed versus Hard temper forming behaviour 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.
