Ni200 vs Ni201: Which Nickel Grade for Your Electrolyzer?
The 0.13% carbon difference between Ni200 and Ni201 determines whether your electrode wire survives 60,000 hours or fails at 20,000. Selection guide with chemical composition, grain-boundary corrosion data, and application recommendations.
What is Nickel Mesh Technical Bulletin?
The Hydromesh technical bulletin is a monthly collection of field-tested engineering notes on nickel mesh and electrode materials, written by the RAS Materials Engineering Team. Each issue covers one practical topic in depth — Raney nickel catalyst preparation and coating, woven vs knitted electrode substrate selection, Ni200 vs Ni201 grade trade-offs, procurement specification, and hydrogen economy trends — for electrolyzer OEM engineers, electrode coaters, and procurement teams.

How to request a quote
- Step 1
Send your specification — product family, grade (Ni200/Ni201/N6), mesh count or packing density, wire diameter, quantity and certification standard.
- Step 2
Our applications team reviews the requirement and replies within one business day — within 24 hours on working days — with availability, lead time and pricing.
- Step 3
Confirm the proforma invoice; a sample Mill Test Certificate (EN 10204 3.1) is included with the quote, and a free 100×100 mm sample is available for standard mesh specifications.
- Step 4
Production, inspection and shipment proceed with the full documentation package — 100% of shipments include the lot-specific MTC.
Certification & traceability
Manufacturing is ISO 9001:2015 certified, and 100% of shipments include an EN 10204 3.1 Mill Test Certificate — OES chemistry, laser micrometer wire trace, optical mesh count and ASTM E8 tensile results — with a traceable heat number on every roll. Technical enquiries receive a substantive reply from a named materials engineer within one business day (within 24 hours on working days), and a sample MTC is included with every quote so your quality team can verify the documentation format up front.
Frequently Asked Questions (FAQ)
What topics does the Hydromesh technical bulletin cover?
Technical articles on Raney nickel catalysts, electrolyzer electrode materials, nickel mesh procurement, and hydrogen economy trends — the same subjects our applications engineers handle in customer RFQs every week.
How often is the technical bulletin updated?
A new issue is published every month. Each article is a field-tested note from the engineers building tomorrow's electrochemistry, not a marketing recap.
Who writes the bulletin?
The RAS Materials Engineering Team — the same group that reviews incoming RFQ specifications and replies to technical enquiries within one business day (within 24 hours on working days).
