7075-T6 — Machining & Properties
Typical properties, what 7075-T6 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 7075-T6
Machinability is rated good — a well-behaved material to machine with correctly chosen tooling and parameters. 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 7075-T6 is ±0.010mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: Hard anodise (Type III), chromate (MIL-DTL-5541F). Full material traceability with MTR and CoC documentation on every order.
Typical applications
Aerospace fittings, UAV/drone frames, defence, performance sports.

7075-T6 — FAQ
What is the density of 7075-T6?
2.81 g/cm³ (typical). That is 2810 kg/m³ — our metal weight calculator uses exactly this figure for 7075-T6.
What is the tensile strength of 7075-T6?
Typically 572 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 7075-T6 easy to machine?
Its machinability is rated good — a well-behaved material to machine with correctly chosen tooling and parameters.
What is 7075-T6 used for?
Typical applications: Aerospace fittings, UAV/drone frames, defence, performance sports.
What tolerance can be held when machining 7075-T6?
Our standard achievable tolerance on 7075-T6 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 7075-T6?
Yes — we machine 7075-T6 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 (Type III), chromate (MIL-DTL-5541F).
