Ni200 Nickel Wire

Name: Ni200 Nickel Wire
Brand: TOPTITECHS
SKU: TT-4675
Availability: InStock

Ni200 nickel wire for battery, welding and electrode applications. High purity nickel, various gauges, soft or half-hard temper available.

Products Specifications

Ni200 nickel wire is drawn from high-purity nickel with diameters from 0.05 mm to 8.0 mm. It combines high electrical conductivity, corrosion resistance, and good weldability, making it a reliable choice for welding consumables, electronic components, resistance wire, and nickel mesh production.

1Product Overview

2Material & Manufacturing

Pure nickel (Ni200/Ni201) offers excellent corrosion resistance in alkaline media and reducing environments, combined with high electrical and thermal conductivity. These properties make it the reference material for alkaline water electrolysis electrodes, battery current collectors, and GDL/PTL media in PEM and AEM cells where stability under high pH and hydrogen evolution is essential.

TOPTITECHS supplies nickel products from vacuum-melted ingots with verified chemical composition per ASTM B160/B162. Dimensional tolerances, surface condition, and electrical conductivity are tested on each production batch, giving customers consistent electrochemical performance in cell stacks.

7Where This Product Fits

Wire and rod products are supplied in coil or straight lengths with controlled diameter tolerance and surface finish, ready for weaving, fastening, welding, spring forming, or machining. Mechanical properties (tensile, yield, elongation) are verified per the applicable ASTM grade so downstream forming processes behave predictably.

For specialty grades such as NiTi memory alloy or TC4 aerospace bar, additional certification (composition, transformation temperature, ultrasonic inspection) is available to support regulated industries.

How to select: specify alloy and grade, diameter and tolerance, mechanical property requirements (tensile/spring temper), surface condition, and whether certification is required. For NiTi, also define the transformation temperature range for your application.

8FAQ

What is the diameter tolerance?

Standard tolerance is ±0.01–0.05 mm depending on diameter; tighter tolerances are available on request. Surface condition (bright, oxide-free, or pickled) is specified at order.

Do you supply with certification?

Yes. Composition and mechanical property certificates are available, including special verification (ultrasonic, transformation temperature for NiTi) for regulated applications.

Can you supply fine nickel wire for mesh weaving?

Yes, we supply fine nickel wire down to 0.05 mm suitable for weaving.
