Machining 7068-T6511

Machinability is rated moderate — machinable without drama, but it rewards proper tooling, feeds and speeds — cycle times sit above the easy-cutting grades. Aluminium has a high thermal expansion coefficient (~23 × 10⁻⁶ /°C). On large features, allow parts and tooling to reach thermal equilibrium before inspection.

Our standard achievable tolerance on 7068-T6511 is ±0.010mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: Hard anodise, chromate conversion. Full material traceability with MTR and CoC documentation on every order.

Typical applications

Ultra-high-strength aerospace structural frames and assemblies.

Reference tool. Values are typical for the grade and condition stated and vary by supplier, temper and batch — they are reference data, not a specification. The Material Test Report supplied with your order is the governing document for the material actually used. Figures are provided in good faith for early design guidance and are not a substitute for the published standard or your own engineering judgement. Always verify against the controlled standard and your drawing before manufacture. If a feature is critical, tell us at quotation stage and we'll confirm it explicitly.
Questions engineers actually ask
