Packing and Delivery from Suppliers
Nickel Strip NI201 is packed in moisture-proof wrapping and export-standard wooden boxes. Coils are securely strapped to prevent damage during transit. Leading suppliers offer worldwide shipping by air, sea, or express delivery with full traceability documentation such as Mill Test Certificates (EN 10204 3.1).
Why Nickel Strip NI201 is Preferred for Industrial Use
NI201 nickel strip provides a combination of purity, stability, and mechanical strength that makes it suitable for continuous operation in both acidic and alkaline environments. Its low carbon composition prevents brittleness during prolonged exposure to high temperatures, ensuring long service life in harsh conditions.
Related Questions
1. What is the main difference between Nickel 200 and Nickel 201 strips?
Nickel 201 has a lower carbon content (≤0.02%) compared to Nickel 200 (≤0.15%), making it more resistant to graphitization and better suited for high-temperature environments above 300°C.
2. Can Nickel Strip NI201 be used for battery welding?
Yes. NI201 strip is frequently used in battery welding due to its excellent electrical conductivity, low resistance, and ease of spot welding. It ensures efficient current flow between battery cells.
3. What certifications should a Nickel Strip NI201 supplier provide?
Reliable suppliers should provide ASTM B162 / ASME SB-162 compliance, ISO 9001 certification, and Mill Test Certificates (MTC). These ensure the nickel strip’s traceability, composition accuracy, and performance reliability.
