Waspaloy — Machining & Properties

Typical properties, what Waspaloy 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 Waspaloy

Machinability is rated extremely difficult — at the extreme end of machinability — a specialist job with significant tooling cost and cycle time, worth discussing before you commit the design. Nickel superalloys work-harden rapidly and generate extreme cutting temperatures. Premium carbide tooling, conservative parameters and flood coolant are mandatory — expect additional cost and lead time relative to standard alloys.

Our standard achievable tolerance on Waspaloy is ±0.020mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: As machined, shot peen. Full material traceability with MTR and CoC documentation on every order.

Typical applications

Gas turbine discs, rings and cases; high-cycle fatigue applications.

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

Waspaloy — FAQ

What is the density of Waspaloy?

8.19 g/cm³ (typical). That is 8190 kg/m³ — our metal weight calculator uses exactly this figure for Waspaloy.

What is the tensile strength of Waspaloy?

Typically 1275 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 Waspaloy easy to machine?

Its machinability is rated extremely difficult — at the extreme end of machinability — a specialist job with significant tooling cost and cycle time, worth discussing before you commit the design.

What is Waspaloy used for?

Typical applications: Gas turbine discs, rings and cases; high-cycle fatigue applications.

What tolerance can be held when machining Waspaloy?

Our standard achievable tolerance on Waspaloy is ±0.020mm under normal conditions (ISO 2768-f general tolerancing). Tighter tolerances on critical features can be agreed at quotation for specific geometries.

Can Dalloway machine Waspaloy?

Yes — we machine Waspaloy 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: As machined, shot peen.
