7068-T6511 — Machining & Properties
Typical properties, what 7068-T6511 is like on a machine tool, what it gets used for, and the tolerance and finishes we hold on it — from a shop that actually machines it, not a datasheet aggregator. Every figure here drives our own calculators.
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.

7068-T6511 — FAQ
What is the density of 7068-T6511?
2.85 g/cm³ (typical). That is 2850 kg/m³ — our metal weight calculator uses exactly this figure for 7068-T6511.
What is the tensile strength of 7068-T6511?
Typically 683 MPa. Treat it as a typical value, not a specification — the Material Test Report supplied with your order states the actual certified figures for the batch.
Is 7068-T6511 easy to machine?
Its machinability is rated moderate — machinable without drama, but it rewards proper tooling, feeds and speeds — cycle times sit above the easy-cutting grades.
What is 7068-T6511 used for?
Typical applications: Ultra-high-strength aerospace structural frames and assemblies.
What tolerance can be held when machining 7068-T6511?
Our standard achievable tolerance on 7068-T6511 is ±0.010mm under normal conditions (ISO 2768-f general tolerancing). Tighter tolerances on critical features can be agreed at quotation for specific geometries.
Can Dalloway machine 7068-T6511?
Yes — we machine 7068-T6511 in-house on 3, 4 and 5-axis milling and CNC turning, from single prototypes to production, with MTR and CoC documentation standard. Typical finishes: Hard anodise, chromate conversion.
