Overview

An aerospace drawing names the grade and the standard it calls for, so the wire that arrives has to be the wire that was specified. The pure nickel wire range is drawn from 0.025 mm to 10 mm to ASTM B164 and GB/T 21653, in four commercial-purity grades (Ni200, Ni201, N4, N6), and every shipment carries the batch records that incoming inspection uses.

What Pure Nickel Wire Does in Aerospace

Aerospace hardware is often associated with nickel-based superalloys such as Inconel, and those alloys carry the blade and nozzle hardware at the top end of temperature and stress. Pure nickel wire takes the supporting positions, where a heat-tolerant conductor or a formable structural wire is what the drawing calls for: temperature-sensor leads and ignition wiring, along with cable connections and woven mesh elements. Where the drawing calls for a superalloy part, that is a separate product line, and where it calls for a machined fitting rather than a wire, pure nickel bar is supplied to the same documentation standard.

Dimensions & Specifications

Micro wire (≤0.05 mm) is available at a 1 kg MOQ; standard wire sizes start at a 5 kg MOQ. Thickness and dimensions can be produced to customer requirements; submit the drawing for review.

Key Strengths

• Heat stability: mechanical properties hold through sustained high-temperature service, with a melting point of 1435–1446°C.

• Oxidation resistance: a stable oxide layer limits further attack in hot air, which is the condition sensor and ignition parts see in service.

• Conductivity: resistivity of 0.096 μΩ·m for sensor leads and ignition wiring.

• Formability: ductile enough for bending and coiling into lead runs, with annealed tensile strength of ≥462 MPa.

• Traceability: batch records and EN 10204 3.1 mill certificates accompany export orders for aerospace incoming inspection.

Technical Details

What Aerospace Drawings Specify

A purchase in this sector differs from general industry on three points. The grade is stated against a standard, ASTM B164 for Ni200 and Ni201 or GB/T 21653 for N4 and N6. The batch is traceable, with the chemistry and dimensions recorded on the certificate. Surface condition is controlled, because contamination or a deep scratch matters in a welded or sealed assembly. Wire is produced and documented against those points.

Where the Wire Serves in Aerospace Hardware

In engine builds the wire goes into sensor leads and burner wiring, where it has to keep its resistance while the surrounding hardware runs hot. Ignition components rely on the same combination of oxidation resistance and conductivity. Airframe and thermal protection assemblies use it in woven mesh and support elements, and aerospace electronics use it for temperature-sensor leads and connecting runs.

Purity and Carbon Choice for the Duty

Ni201 (≥99.0% Ni, C ≤0.02%) is the low-carbon grade for positions that see sustained heat, since carbon held at 0.02% keeps ductility over long exposure. Ni200 (≥99.2%) covers general aerospace wiring at a lower price per kg, and N4 (≥99.9%) and N6 (≥99.5%) follow the GB designation system when the drawing calls them out. All four are commercial-purity nickel, and the certificate states the batch chemistry against the UNS or GB limits.

Records Behind Each Production Stage

Coming off the melt, the wire passes through multi-pass cold drawing and annealing, then surface treatment and protected packing. Each stage carries its own record, from drawing parameters through to the dimensional and mechanical test results. The batch number joins those records to the certificate, so a delivered spool can be followed back through drawing and annealing to the material it came from.

Physical & Mechanical Properties

Quality Assurance

Composition by analysis, dimension and surface condition are checked, and mechanical properties are tested, before release. The results are filed against the batch number that appears on the certificate and the spool label. Export orders ship with EN 10204 3.1 mill test certificates.

Packaging & Delivery

Micro and fine wire is wound on spools and packed in carton boxes; larger diameters are supplied as coils in polybags or on spools as requested, with moisture- and oxidation-protected packaging. Delivery is 7–15 days for standard production, 3–7 days for small in-stock quantities, and 15–30 days for complex custom requirements confirmed against the drawing.

About the Factory

The certificate that ships with an aerospace order names the grade, the diameter and the batch chemistry, and that batch can be followed back through drawing and annealing to the material it came from. DZX has run a nickel-focused line since 2002, holds ISO 9001 and SGS certification, and brings 20+ years of drawing experience, 50+ patents, 1,000+ product configurations and 2,000+ partners across 60+ export countries.

FAQ

Which grade is specified for aerospace wiring?

Ni201 (≥99.0% Ni, C ≤0.02%) for positions that run hot, because the low carbon keeps ductility over long exposure. Ni200 (≥99.2%) for general wiring at a lower price per kg. N4 (≥99.9%) and N6 (≥99.5%) when the drawing uses the GB designation system.

What is the purity limit for each grade?

Ni+Co runs at ≥99.9% for N4, ≥99.5% for N6, ≥99.2% for Ni200 and ≥99.0% for Ni201, with carbon capped at 0.02% in Ni201 and 0.15% in Ni200. The certificate states the analysis of the batch supplied.

Which tempers are supplied for bending and coiling?

Soft, hard and 1/2 hard. Soft temper suits bending and coiling into lead runs; hard or 1/2 hard holds a self-supporting shape. Tolerances are set per drawing, with the tightest band on micro sizes.

What documents ship with aerospace orders?

EN 10204 3.1 mill test certificates covering chemical composition, dimensions and mechanical properties, together with batch test records tied to the batch number on the spool label.

What is the MOQ and sample policy?

Micro wire (≤0.05 mm) starts at 1 kg; standard wire at 5 kg. Samples are free for N6/Ni200 (0.5 kg); N4/Ni201 samples are charged and refunded on a first order of 50 kg or more.

What is the delivery time?

Standard production ships in 7–15 days, small in-stock quantities in 3–7 days, and complex custom requirements in 15–30 days after the drawing is approved.
