2024-T4 — Machining & Properties
Typical properties, what 2024-T4 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 2024-T4
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 2024-T4 is ±0.010mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: Hard anodise, chromate conversion (MIL-DTL-5541F). Full material traceability with MTR and CoC documentation on every order.
Typical applications
Aircraft structural, high-stress brackets, defence.

2024-T4 — FAQ
What is the density of 2024-T4?
2.78 g/cm³ (typical). That is 2780 kg/m³ — our metal weight calculator uses exactly this figure for 2024-T4.
What is the tensile strength of 2024-T4?
Typically 470 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 2024-T4 easy to machine?
Its machinability is rated good — a well-behaved material to machine with correctly chosen tooling and parameters.
What is 2024-T4 used for?
Typical applications: Aircraft structural, high-stress brackets, defence.
What tolerance can be held when machining 2024-T4?
Our standard achievable tolerance on 2024-T4 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 2024-T4?
Yes — we machine 2024-T4 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 (MIL-DTL-5541F).
