Nylon PA6 — Machining & Properties

Typical properties, what Nylon PA6 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 Nylon PA6

Machinability is rated good — a well-behaved material to machine with correctly chosen tooling and parameters. Engineering polymers have significantly higher thermal expansion coefficients than metals. All plastic components must be inspected at a controlled temperature, and tolerances tighter than ±0.020 mm are generally not maintainable in service without dimensional constraints in the design.

Our standard achievable tolerance on Nylon PA6 is ±0.050mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: Moisture-absorbing; dimensions change with humidity. Full material traceability with MTR and CoC documentation on every order.

Typical applications

Gears, wear pads, rollers, guide rails, cable management.

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

Nylon PA6 — FAQ

What is the density of Nylon PA6?

1.14 g/cm³ (typical). That is 1140 kg/m³ — our metal weight calculator uses exactly this figure for Nylon PA6.

What is the tensile strength of Nylon PA6?

Typically 80 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 Nylon PA6 easy to machine?

Its machinability is rated good — a well-behaved material to machine with correctly chosen tooling and parameters.

What is Nylon PA6 used for?

Typical applications: Gears, wear pads, rollers, guide rails, cable management.

What tolerance can be held when machining Nylon PA6?

Our standard achievable tolerance on Nylon PA6 is ±0.050mm under normal conditions (ISO 2768-f general tolerancing). Tighter tolerances on critical features can be agreed at quotation for specific geometries.

Can Dalloway machine Nylon PA6?

Yes — we machine Nylon PA6 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: Moisture-absorbing; dimensions change with humidity.
