Alloy basis

It offers higher strength than many 6xxx alloys while retaining useful corrosion resistance and weldability.

Typical applications

Structural frames, bridges, cranes, transport, machined components, marine structures and heavy extrusions.

Common tempers / conditions

Common tempers include T4, T6 and T651.

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.
