Silver oxide electrical contact material and preparation method thereof

2022/08/29

Material composition (mass fraction): 5%～12%SnO2, 2%～8%ZnO, 0.5%～5%CuO, 0.1%～1%NiO, 0.1%～0.5%In2O3, 0.1%～0.5%Bi2O3, oxidized The particle size of the material is 0.1 to 10 μm, and the remainder is Ag. 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, and meet the requirements of high-power relay composite rivet contacts, which can be partially or completely Instead of AgCdO, it is used in high-power relays!

Fixed connection contacts. Refers to electrical contacts that cannot move relative to each other between the conductors that are connected by contact. Such as busbar joints, lead connections of electrical equipment, etc.

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.
