Solid Rivet Contacts
NN Inc. solid rivet cold heading machines uses a single base materials. Materials available range from copper and silver alloys. Cold heading equipment are high speed precision mechanical devices capable of high-volume production.
Contact rivet design to optimize the reduction of sticking, surface erosion, material transfer and electrical resistance.
Bimetal Contact Rivets
NN Inc.’s bimetal contact rivet cold heading machines use two materials that must be joinable, fused into a single rivet during the cold heading process. Materials available range from copper and silver alloys.
Bimetal contacts utilize these two different materials to optimize performance characteristics such as sticking, surface erosion, material transfer, and electrical resistance.
