Technical Specifications

Type N Stranded Wire — Nicrosil / Nisil at −270°C to +1300°C, multi-strand (7 / 19 / 37) from φ0.1mm – φ5.0mm, supplied to IEC 60584-1 Class 1.

How to specify Type N Stranded Wire

1. Confirm the alloy for your operating temperature — Nicrosil / Nisil, rated −270°C to +1300°C in air.
2. Pick the conductor diameter from φ0.1mm – φ5.0mm (diameter tolerance ±0.005mm (fine) / ±0.02mm (standard)) — supplied as 7, 19 or 37 strand Nicrosil / Nisil construction for −270°C to +1300°C.
3. Choose the temper condition for this N · Nicrosil / Nisil wire — Hard (cold-drawn) / Soft (annealed) / Bright finished. Soft or annealed tempers are usual where multi-strand N wire is routed around moving parts.
4. Choose the surface finish for N · Nicrosil / Nisil — Bright / Oxidized / Electro-polished. Finish is selected for the service environment along the flexing run.
5. Choose the packaging — DIN 125 spool / Coil / Custom reel, standard coil weights 5kg / 10kg / 20kg standard. Spooled so the N multi-strand pays out without twisting.
6. Quote Type N Stranded Wire against IEC 60584-1 Class 1 and request the MTC / EMF calibration certificate with the batch number for traceability.

Which thermocouple type fits the job

These are the N-type ranges as quoted for solid wire; the same Nicrosil / Nisil alloys are available in the multi-strand form described on this page. Confirm the type first, then choose the strand configuration.

Frequently Asked Questions

What makes Type N more stable than Type K above 1000 °C?

The Nicrosil positive leg (NiCrSi 84.4/14.2/1.4) contains 1.4% silicon, which forms a protective SiO₂ sub-layer and suppresses the chromium oxidation that causes green rot. Type N drift stays within ±1 °C after 500 h at 1000 °C.

What temperature range and diameters does Type N stranded wire cover?

−270 °C to +1300 °C, in diameters from φ0.1 mm to φ5.0 mm, in 7, 19 or 37 strand constructions.

Why choose stranded Type N rather than solid?

For high-temperature or vacuum installations that also vibrate — heat treatment and turbine work where a solid conductor would work-harden and break.
