Silver Nickel Electrical Contact
Electrical Contact factory, more than 10 years manufacture experience, attained ISO9001, work on OEM and ODM projects.
1. Introduction of Silver Nickel Electrical Contact
Silver nickel AgNi electrical contact has a high level of electrical and thermal conductivity, good plasticity and arc corrosion resistance, as well as a very low contact resistance.
2. Application of Silver Nickel Electrical Contact
Mainly usedin all kinds of switch, controller, voltage regulator, circuit breaker, automotive electrical, magnetic starter, and so on. Normally suit for the electric current which below 100A, AgNi10 is commonly used to the AC contactor below 20A, AgNi (15 ~ 40) are able to bear a larger electric load.
