TRI-METAL CONTACTS RIVETS
This unique product, has been for the first time introduced in India by the PARADISE house and excellently serves the requisite purpose with crown of success. We have equipment capable to produce tri-metal contact rivets with diameter between 2.0 mm to 10 mm.
​
Over and above the advantages claimed by bi-metal contact rivets, it is double headed, with head tip layer and shank tip layer of precious contact material while the base material is OFHD Copper. The shank end will be rivetted over to form the second contact head,when in use.
​
Products in forms of rivet and disc can be available with perfect metallurgical bond having the precious contact materials layer thickness generally in 50% or any desired ratio to suit individual application.

BIMETAL CONTACT RIVETS
Due to high price of silver,this type of rivets are very popular they are replacing solid contact rivets. The shank and part of its head are made of cheaper base metal (generally OFHC Copper) and the upper part of the head is only made of precious contact materials.
The base metal and contact materials are welded in an absolutely reliable way. The technique, of using more Copper and less precious materials, makes larger heads and shanks economically possible and this facilitates proper heat absorption and dissipation and alloys for higher ampere ratings.
The range of head diameter which can be produced by our equipment is 2.0mm-10mm.
