Pure silver has a high level of electrical and thermal conductivity, good plasticity

and arc corrosion resistance, as well as a very low contact resistance. It is easily

soldered and is the ideal contactor material for continuous, enclosed electric

connectors. It is one of the most widely used automatic control switches,

thermostats, baking machines, oven, timers, thermal relays, and computers.

 

AgCu contact:

This contact has good electrical conductivity and its surface is not liable to

oxidization. The addition of 3-28% copper may remarkably improve the silver

flame resistance. Hence, copper contact metrical may be used in current strength.

 

up to 16A. The addition of copper, especially of high copper content, for example

10%, will greatly reduce material transferring during DC working conditions. It

is widely used in AC contactors, relays, electric tool switches, buttons, timers,

and other household electrical appliance.

 

Fk Ag contact rivet

This fine crystal silver contains a 0.12% nickel additive and has a low contact

resistance, which is similar to that of pure silver, without the variable switching

times. Its fusion welding and flame resistance is slightly higher than that of

pure silver, and under almost equal contact resistance, its strength and heat

resistance are higher than that of a silver-copper composite contactor. It is suitable for various temperature adjustments of working current 10A
