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.

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.
