- Tin plating: relatively cheap, soft texture, requires high contact force to ensure conductivity, low plug-in and pull-out times, not wear-resistant, can only play a simple anti-corrosion role, brass or bronze tin plating working temperature can reach 110℃, steel tin plating can reach 190℃.

- Gold plating: used for spring pins that require high reliability, transmit small signals and have low contact force, chemically inactive, not easy to oxidize, and has good corrosion resistance.
