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.

SOLID CONTACT RIVETS
This type of contact is manufactured directly from wire by cold heading process as a result of which the shank remains soft for easy rivetting whilist the head becomes work-hardened.
​
The shank length can be easily varied but the shank diameter should be in right proportion to the size of head for avoiding wrinkles during cold forging operation. For satisfactory results, a sufficiently large shank diameter (generally 50% of the head diameter) should be selected to avoid undue increase of contact resistance during service.
