Platinum — Machining & Properties

Typical properties, what Platinum 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 Platinum

Machinability is rated moderate — machinable without drama, but it rewards proper tooling, feeds and speeds — cycle times sit above the easy-cutting grades. 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 Platinum is ±0.010mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: Extremely high intrinsic value — formal handling agreement required. Full material traceability with MTR and CoC documentation on every order.

Typical applications

Medical implant components, laboratory crucibles, scientific apparatus.

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

Platinum — FAQ

What is the density of Platinum?

21.4 g/cm³ (typical). That is 21400 kg/m³ — our metal weight calculator uses exactly this figure for Platinum.

What is the tensile strength of Platinum?

Typically 240 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 Platinum 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 Platinum used for?

Typical applications: Medical implant components, laboratory crucibles, scientific apparatus.

What tolerance can be held when machining Platinum?

Our standard achievable tolerance on Platinum 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 Platinum?

Yes — we machine Platinum 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: Extremely high intrinsic value — formal handling agreement required.
