Product Description

ELECTRICAL CONTACTS FOR LOW VOLTAGE

:: BIMETAL CONTACT RIVETS::

Bimetal Contact Compares with solid contact except in price

A layer of silver alloy forms the contact surface. The rest of the head and the shank are made of copper.

 

PERFORMANCE

Contact surface layer and backing metal are bonded metallurgically. This ensures the electrical and mechanical properties  are as good as solid contacts. Electrolytic Copper provides better thermal and electrical conductivity than silver alloy and copper shank ensures longer life. With increasing silver prices, lower silver content of it allows choice of larger contact than with solid silver contact to get better performance.

FEATURES

• Contact layer is normally half the thickness of the head. To suit specific requirements, variation on this ratio is possible within practical limits.

• Contact layer can be made of silver alloys like AgNi 10%, AgCd 10%, AgCdO 15%. Variations of this alloys can also be offered.

• Contacts can be silver plated if required.

SPECIFICATION

We hold stock as per standard dimensions shown below to facilitate production planning and reduce inventory cost. For contacts of othr materials and sizes we offer short deliveries as we have modern high speed manufacturing machinery.
