99.9% Pure Nickel Wire with Low Magnetic Permeability High Thermal Conductivity and Excellent Weldability for Industrial Applications
Overview
Low MOQ and samples first: start this 99.9% pure nickel wire with a small order, qualify the material, then scale. The wire pairs low magnetic permeability with high thermal conductivity and excellent weldability — precision-drawn from 0.025 to 10 mm. Nickel content is 99.9% minimum (N4/NP1). For related pure nickel wire options and pure nickel strip for battery use, browse the DLX catalogue. Produced on our own nickel-alloy line, every spool is inspected per batch before packaging.

Technical Deep Dive
1. Low Magnetic Permeability
Low magnetic permeability makes the wire suitable for electronics and instrumentation applications where magnetic interference must be minimized. The Curie temperature of 358°C anchors the magnetic transition, and the material's magnetic behaviour is confirmed against the application.
2. High Thermal and Electrical Conductivity
Thermal conductivity of 70.2 W/m·K (Ni200) and electrical resistivity of 0.096 μΩ·m at 20°C place the wire as an effective conductor of both heat and current — the combination demanded in electronic and thermal management applications.
3. Excellent Weldability and Formability
The wire is compatible with conventional welding, brazing and soldering processes, and responds well to hot rolling, cold forming and machining — practical for assemblies that must be joined and shaped.
4. Sample and Low-MOQ Start
Samples and small-batch orders are available before series production, so you can verify diameter, weld response and performance against your process. Once qualified, the same specification carries into production volume.
5. In-House Production and Inspection
Our production process includes melting, drawing, heat treatment, finishing and testing — a full in-house chain. Every spool passes chemical composition analysis, diameter inspection and surface checks before packaging.
