Gold — Machining & Properties
Typical properties, what Gold 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 Gold
Machinability is rated good — a well-behaved material to machine with correctly chosen tooling and parameters. Precious metal machining requires a formal chain-of-custody agreement and swarf recovery protocol before work commences. Customers are typically expected to supply their own raw material.
Our standard achievable tolerance on Gold is ±0.010mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: Customer material supply preferred; swarf fully recovered. Full material traceability with MTR and CoC documentation on every order.
Typical applications
High-value display components, luxury goods, scientific contacts.

Gold — FAQ
What is the density of Gold?
17.4 g/cm³ (typical). That is 17400 kg/m³ — our metal weight calculator uses exactly this figure for Gold.
What is the tensile strength of Gold?
Typically 205 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 Gold easy to machine?
Its machinability is rated good — a well-behaved material to machine with correctly chosen tooling and parameters.
What is Gold used for?
Typical applications: High-value display components, luxury goods, scientific contacts.
What tolerance can be held when machining Gold?
Our standard achievable tolerance on Gold 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 Gold?
Yes — we machine Gold 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: Customer material supply preferred; swarf fully recovered.
