Material basis

Typical heat-treatable sequence is solution heat treatment, quenching and natural/artificial aging. Non-heat-treatable alloys may be annealed to restore formability.

Applications

Used for 2xxx, 6xxx and 7xxx alloys and some castings.

Common grades / designations

Temperature control, quench delay, distortion, residual stress and aging schedule are critical to consistent properties.

Selection and procurement checks

Confirm alloy, temper, product form, dimensions, applicable ASTM/EN/ISO/AA specification, mechanical properties, corrosion environment, joining route and mill certification before approval.

Element Folio engineering reference. Verify the latest governing specification and manufacturer data for final design or procurement.
