Nickel 200/201 (899L) – UNS N02200, N02201 – WNR 2.4068
Nickel 201/200 strip (899L) is our premier battery grade that offers improved conductivity over Nickel 200 and Nickel 201 strip while maintaining closer mechanical properties to the lower conductivity materials.
Nickel 200/201 (899M) – UNS N02200, N02201 – WNR 2.4068
Nickel 201/200 (899M) is produced as a replacement for Nickel 200 material and Nickel 201 strip with similar mechanical properties and without the higher conductivities attributed to higher purity grades such as 899L and 899A.
We offer these two high purity, roll compacted Nickel Strip grades as a replacement for Nickel 200 and Nickel 201 strip. Our roll compacted material provides higher purity than standard wrought and cast Nickel Strip. The higher purity reduces impedance, increases conductivity, and therefore improves performance.
Applications
Battery connectors and tabs used to combine multiple individual batteries into a pack.
