Alloy basis

It is precipitation hardenable and frequently used in plate and forgings.

Typical applications

Aircraft wing structures, bulkheads, fuselage frames and thick aerospace machined components.

Common tempers / conditions

Common tempers include T7451 and T7651.

Engineering selection notes

Confirm the exact alloy designation, temper, product form, thickness/diameter, mechanical properties, corrosion environment, joining process, surface treatment and certification. Properties can vary substantially by temper and product form.

QA/QC

For critical service, verify heat/lot traceability, mill certificate, chemical composition, tensile properties, temper, dimensional tolerances and any required NDT or third-party inspection.

Element Folio engineering reference. Verify the latest governing standard and producer data before design or procurement.
