Alloy basis

It is precipitation hardenable and frequently supplied clad for corrosion protection in sheet applications.

Typical applications

Aircraft skins, wing structures, fittings, fasteners, machined aerospace parts and high-performance structures.

Common tempers / conditions

Common tempers include T3, T351, T4 and T851 depending on product form.

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.
