Frequently Asked Questions

01 What is NP1-grade nickel wire?

NP1-grade nickel wire is ultra-pure nickel at 99.99% purity, 0.025mm diameter, conforming to the GOST 492 standard. It is a precision industrial material distinct from commodity nickel.

02 How is the 99.99% purity validated?

Purity is validated by independent laboratories using ICP-MS spectrographic analysis (NSL Analytical USA) and confirmed by multiple academic institutions including IIT Delhi and NTU Singapore.

03 What applications use NP1 wire?

EMI/EMC shielding (65-75 dB attenuation), aerospace and defence, green hydrogen electrolysers (94.3% efficiency with RuO₂ coating), marine and desalination, thermal power, semiconductors, and rare earth recovery.

04 Why does diameter matter for performance?

At 0.025mm diameter, NP1 wire provides extreme surface-area-to-volume ratio, enabling superior electromagnetic shielding, electrochemical activity for hydrogen production, and precision performance in aerospace wire applications.
