Silver Alloy Bimetal Contact Buttons

  Silver alloy Bimetal contact buttons

Product Overview:
Bimetal contact buttons can be supplied in a large varity of configurations and combinations of materials.The material of the working layer may be Ag,AgCdO,or AgNi.For the side to be welded to the support material steel or Cu-Ni alloy can be used.The thickness of top working layer is within half of the top layer thickness,In the standard design the contact buttons have 3,5 or 7 spherical projections.Other numbers of projections and shapes of the projections,however,all are possible.

Main Materials: 

Main face Materials: Ag,AgNi,AgSnO2,AgZnO

Main base materials: Copper,brass, Steel, 

Product Types: 

Bimetal button contact, trimetal button contact, square contact

Main Application:

Bimetal Contact buttons are used by means of the impulse welding technique Components produced by this method are utilized,e.g., in temperature controllers or small power relays.

Performance Characteristics:

1. Pure Silver contact rivet:

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.

   2. Fine crystal silver contact rivet:

This fine crystal silver contains a 0.15% nickel additive and has a low contact resistance, which is similar to that of pure silver, without the variable switching times.

  3. Ag Cu bimetal rivet:

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

   4. AgNi /Cu bimetal rivet:

In low voltage engineering, this contact is widely used in AC switches as an electrical contact.

 5. AgCdO/Cu bimetal rivet:

This contact includes AgCdO10, AgCdO12, AgCdO15, and this kind of electrical contact has one of the most important materials in silver - metal oxide contact material.

   6. AgZnO/Cu bimetal rivet:

The oxide of this contactor is more thermally stable than CdO.

   7. AgSnO2 and AgSnO2 In2O3 and bimetal rivet:

 AgSnO2 and AgSnO2In2O3 are the ideal environment-protecting materials to instead of AgCdO.
