Why should a sterling silver block or a silver-based alloy block be placed on the electrical alloy contact?

2022/08/29

The contact surface of the contact will oxidize when it is in contact with the atmosphere. If the copper is oxidized, a copper oxide or cuprous oxide film will be formed on the surface. The oxide film of copper has poor conductivity, and its resistivity is more than 1016 times larger than that of pure copper. Therefore, the contact resistance of the copper contact after oxidation is very large, and an unacceptable temperature rise will occur when the current is passed.

YAMEI

The raw material of the invention adopts multi-phase reinforcement, and combines the advantages of each reinforcement phase, so as to achieve the purpose of good processing performance and excellent electrical performance of the material in the production process.

Soldering and repairing technical points of power silver contacts

Silver contacts are widely used in power systems, especially in high-power equipment, silver contacts must be used to conduct current

What to pay attention to when using silver contacts

Silver contacts usually refer to the intersection of electrical and electronic components when opening and closing, and the intersection of metal conductor terminals is prone to instantaneous heat and sparks when touched, which promotes the multi-frequency process of electronic contacts.
