Changzhou DLX Alloy Co., Ltd. manufactures high-purity NP2 (N6) industrial nickel wire from its 20,000+ m² production facility with a stable capacity of 1,200 tons per month. Engineered with Ni+Co ≥ 99.5% (typical purity 99.6%), NP2 nickel wire provides exceptional resistance to caustic reducing media, alkaline solutions, and high-temperature oxidation.
Drawing from ultra-fine 0.025 mm micro wire up to 10.0 mm heavy-duty wire, DLX maintains rigorous dimensional tolerances and surface cleanliness required for SOEC hydrogen electrolysis meshes, vacuum electronic grids, precision wire-wound resistors, and chemical processing components. Each production batch is fully traceable with EN 10204 3.1 Material Test Certificates.
1. Corrosion Resistance & Chemical Stability
NP2 (N6) pure nickel wire offers superior resistance in hot concentrated caustic alkalis (NaOH, KOH) and non-oxidizing acid environments. The controlled low-carbon and low-impurity composition prevents intergranular embrittlement during thermal cycles, ensuring prolonged service life in chlor-alkali production, chemical synthesis reactors, and SOEC hydrogen cells.
2. Thermal and Physical Performance Parameters
Featuring a fixed melting point of 1435°C-1446°C and a Curie temperature of 358°C, NP2 wire preserves mechanical stability across extreme operational envelopes. In annealed state, the material exhibits a shear modulus of ~76 GPa, tensile strength ≥420 MPa, and hardness within 90-120 HB, preventing premature fatigue in continuous vibration or winding operations.
3. Electrical Conductivity & Micro-Wire Specifications
With electrical resistivity of 0.096 μΩ·m at 20°C, NP2 pure nickel wire ensures high thermal and electrical conduction efficiency. Below are reference calculated values for standard wire gauges:
| Grade | Ni Content | Best Application | Reference Price (FOB, USD/kg) |
|---|---|---|---|
| N4 (NP1) | ≥99.9% | Vacuum electronics | 420-480 |
| Ni201 | ≥99.0% | High-temp service | 350-390 |
| Ni200 | ≥99.2% | Battery, chemical | 340-380 |
| N6 (NP2) | ≥99.5% | Industrial corrosion | 300-340 |
Reference prices are FOB indicative ranges per grade; final quotation depends on size, quantity and delivery terms.
