NP1: the specification apex of precision nickel.

Specification

Why NP1 and not a commercial grade

Commercial nickel is routinely specified at 99.5 % or 99.8 % purity — more than sufficient for stainless steel and the majority of plating applications. The green-transition verticals sit above this band. They need the fourth decimal point because the fourth decimal is where grain-boundary failure modes, coating-adhesion defects and catalytic poisoning pathways disappear.

In alkaline electrolysis at 80 °C, the difference between NP1 and Class-1 Ni at the same RuO₂ loading is 16.2 percentage points of Faradaic efficiency (94.3 % versus 78.1 %)^[1]. In planar EMI shielding, the difference is ~18 dB across the 30 MHz–16 GHz sweep^[2]. In ASTM B117 salt-spray, the difference is ~850 hours of service life^[3].

GOST 492 and the Russian precision-wire tradition

GOST 492-2006 is the Russian/Eurasian standard for wrought nickel and nickel alloys^[4]. The NP1 grade within that standard specifies ≥99.99 % Ni with bounded trace maxima for copper, iron, cobalt, sulphur and carbon. The Russian precision-wire tradition — which predates the Western aerospace boom — remains the reference source of ultra-pure nickel wire. GTX reservoir material carries verified chain-of-custody documentation back to the original metallurgical lot.

Conversion pathways

Wire is rarely the functional form. NP1 wire is converted into four principal outputs:

1. Precision mesh — 200, 400 and custom mesh counts for EMI shielding, electrolyser electrodes, marine filtration and thermal-power cooling loops.
2. Wire braids — cryogenic-to-high-temperature looms for aerospace and defence (qualified −196 °C → 1000 °C).
3. Coated substrates — mesh + RuO₂/IrO₂ coating stacks for alkaline electrolysis and chlor-alkali.
4. Custom fabrication — semiconductor chucks, REE-recovery filters, composite autoclave linings.

Provenance and custody

The 7,026,905 m reservoir is held at a Swiss vault with independent attestation by ASACERT (audit ASACERT-2025-CERT-06). Movement from vault to conversion partner is governed by the group chain-of-custody protocol documented on the About page. Lot-level traceability from vault to finished mesh is a contractual requirement for defence and aerospace contracts.
