NPCS Nickle Plated Copper Strip With H65 Base Strip Used For Precision Electronic Connectors
Description:
This series of products with good electrical and thermal conductivity, ductility, deep impact and corrosion resistance,
it can be used in electrical appliances, construction, chemical industry, sealing gaskets, transformers, water heaters etc.
Nickel plating: The process of electroplating a layer of nickel on a metal or some nonmetal by electrolysis or chemistry.
Material Type: T2, H62, H65, H85.
Specification: thickness (0.1mm-3mm) width (2mm-200mm).
Advantages of nickel-plated copper strip:
1, Good welding function
2, Anti-electromagnetic stirring
3, Cheap price
4, With higher chemical fluctuation, in sulfuric acid, nitric acid, in the dilute solution of hydrochloric acid is simply not dissolved.
Application scope of nickel-plated copper strip:
1. Electronic connector,
2. Lead frame,
3. Relay spring plate,
4. Switch contact plate,
5. Precision electronic connector,
6. Terminal,
7. High-power battery connector,
8. Button battery cathode material,
9. Electronic material,
10. Connection between lithium battery anode
11. PCB board and other industries.
