| High Light | Ni 200 4P Pure Nickel Strip ，Anti Corrosive 4P Pure Nickel Strip ，Pure Nickel Strip For 18650 Battery | ||
Corrosion inside a battery pack does not announce itself. A nickel-plated steel strip looks fine at final QC — bright, clean, passing the continuity test. Twelve months later, in a coastal climate with 80% average humidity, the micro-cracks that formed at every spot weld have let moisture reach the steel core. Rust bridges across the cell terminals. Internal resistance climbs. The BMS trips. The pack comes back under warranty. DLX's Ni200 4P strip eliminates this failure at the material level: 99.6% minimum nickel, solid through the entire cross-section, with no steel substrate to corrode. Stamped at 19.5mm pitch, 49.5mm width for standard 18650 layouts, hydrogen-annealed to a bright finish that requires no pre-cleaning — just load, index, and weld.
| Grade | Ni Content | Corrosion Performance | Recommended Environment | Reference Price (FOB, USD/kg) |
|---|---|---|---|---|
| N4 | ≥ 99.9% (Ni+Co) | Maximum — Fe ≤ 0.04% eliminates localized corrosion initiation sites | Marine, coastal, tropical outdoor — condensing humidity year-round | 62 – 70 |
| Ni200 | ≥ 99.6% | Excellent — the industry standard for anti-corrosive battery interconnects | E-mobility, outdoor power equipment, humid indoor environments | 54 – 60 |
| Ni201 | ≥ 99.0% (C ≤ 0.02%) | Very good — low-carbon for thermal cycling without sensitization | Fast-charge packs, high-temperature industrial modules | 50 – 57 |
| N6 | ≥ 99.5% (Ni+Co) | Good — indoor/controlled-climate environments | UPS, indoor energy storage, climate-controlled telecom | 38 – 45 |

Changzhou DLX Alloy Co., Ltd. takes the position that anti-corrosive performance should be engineered into the metal, not sprayed onto it. Since 2002, our 12,000 m² nickel-only facility in Changzhou has produced solid nickel strip — not nickel-plated steel, not nickel-clad copper — for battery manufacturers who cannot afford corrosion-related field failures. Every production batch is sampled for 96-hour ASTM B117 salt spray exposure, with plated-steel controls run alongside so the difference is measured, not assumed. This testing discipline, combined with ISO9001-certified processes and EN 10204 3.1 material certification per heat, means the "anti-corrosive" on our label is a verified specification — not a marketing adjective. Serving 40+ countries at 500 tons monthly capacity.
Request a sample and run your own salt spray test — or review ours. DLX includes ASTM B117 salt spray results (96 hours, 5% NaCl, 35°C) for every production batch upon request. We also run nickel-plated steel control coupons from a commercial source alongside our Ni200 samples, so you can see the quantitative corrosion difference under identical test conditions. Zero red rust on Ni200 after 96 hours is the standard; plated steel typically shows rust spots at weld points within 24–48 hours.
Pure nickel in a marine atmosphere forms a thin, adherent nickel oxide/hydroxide passive film that is chemically stable and self-limiting — it grows to a few nanometers and stops. Unlike iron oxide (rust), which is porous, voluminous, and continuously propagates, nickel's passive film is dense and protective. This is the same mechanism that makes Monel (Ni-Cu) propeller shafts survive decades in seawater. For 18650 packs deployed on fishing vessels, coastal telecom towers, or tropical outdoor ESS cabinets, solid Ni200 strip will not rust.
Yes — positively. Hydrogen annealing at 850–950°C chemically reduces any surface nickel oxide formed during rolling and slitting back to pure metallic nickel. It also decomposes and volatilizes organic lubricant residues. The result is a chemically clean, oxide-free surface that forms its natural passive film uniformly — without the uneven oxide patches that can act as local corrosion initiation sites on non-annealed strip.
For 95% of 18650 pack environments — including outdoor e-mobility, power tools used in humid conditions, and coastal-installed ESS — Ni200 at 99.6% Ni provides more than adequate corrosion protection. Upgrade to N4 (99.9% Ni, Fe ≤ 0.04%) only if your packs are deployed in continuous salt-spray conditions (offshore, marine vessel, tropical coastal with no enclosure) or if trace iron is unacceptable for your application's specification. The cost premium for N4 is approximately 15–20%.
Yes. The same Ni200 chemistry is available in any width from 5–240mm, any thickness from 0.05–1.0mm, and any pitch from our standard die library (18.5/19.0/19.5/20.2/20.5mm) or custom-tooled to your specification. Custom tooling lead time is 10–12 working days via our in-house Sodick EDM shop. MOQ remains 5 kg regardless of whether the dimensions are standard or custom.
