Scope of application:
This product is suitable for manufacturing conductors for wires and cables, connectors for electronic products, and other components required for electronic devices.
It is suitable for use in environments below+250 ℃.
Specifications and main technical parameters:
1) Wire diameter range: Φ 0.05-2.0mm
2) Nickel content: 5 grades including 2%, 4%, 7%, 10%, and 27%
3) Deviation in wire diameter:
The deviation of the nominal diameter of nickel plated copper wire should comply with the following table

Nominal diameter	bias
0.050—0．250	±0.008 — ±0.003
>0.250—1.300	±3%d—±1%d
>1.300—2.000	±0.038—±0.013

4) Wire resistance: in accordance with the following table

level	The resistivity ρ 20 Ω. mm2/m shall not exceed
two	zero point zero one seven nine six zero
four	zero point zero one eight three four two
seven	zero point zero one eight nine four seven
ten	zero point zero one nine five nine two
twenty-seven	zero point zero two four two eight four

5) Elongation rate%, in accordance with the following table

Nominal diameter mn	2.4.7.10 Level	Level 27
0.05-0.1	twelve	six
0.1-0.23	twelve	eight
0.23-0.5	sixteen	twelve
0.51-2.0	twenty	sixteen

6) After the polysulfide test, the surface of the nickel plated copper wire remains black, and the above test is not required for nickel layer thickness less than 0.0013mm.
7) After winding and immersion testing, the surface of nickel plated copper wire shows no strain, blackening, or cracking.
