NP1 Ultra-Pure Nickel Wire
GTX NP1 ultra-pure nickel wire, 0.025 mm diameter, 99.99% purity, drawn to GOST 492 specification. The baseline raw material for precision mesh, fabricated assemblies, electrolyser substrates and aerospace qualification.
The 0.025 mm baseline — the foundation of the GTX product family.
All GTX mesh and fabricated assemblies are woven and assembled from this wire. Supplied in its own right for customers who convert in-house or integrate the wire directly into their own fabrication chain. 99.99% NP1 purity, bright-drawn, oxide-free, batch-traceable to the Swiss-vaulted parent reservoir.
Datasheet · verified tolerances.
Supplied on precision spools or to customer-specified packaging. Custom diameter adjustments within the 0.022 – 0.028 mm band available by agreement.

Verified across five independent institutions.
Purity and chemistry are verified by NSL Analytical (USA). Mechanical and thermal behaviour is characterised at NTU Singapore under Prof. Ramamurty’s extreme-temperature cycling regime. Aerospace-grade qualification is issued by Lectromec under NASA-certified and ISO/IEC 17025:2017 protocols. Specification conformity is audited by ASACERT UK.
