Product Description


NC Bimetal Rivet Production Area


SAIJIN has been producing electrical contact rivets since 1998. Each year, we produce hundreds of millions of cold headed solid and bimetal contacts. In addition, we use cold forming technology to manufacture other specialty parts..


We produce cold headed contacts from a wide variety of materials.
Typical alloys include:

  • Silver(Ag)
  • Fine grained silver(FAg)
  • Silver-Nickel(AgNi10/15/20)
  • Silver-Iron
  • Silver-Graphite
  • AgSnO210/12,AgZnO8/10,AgC/AgW
  • Silver-Cadmium Oxide      
  • Silver-Tin Oxide
  • Gold
  • Platinum
  • Palladium
  • Paliney® alloys
CrossSection of Autostaked bimetal contact



Our focus is on producing high quality cold headed contacts at a competitive price. Customers find that due to SAIJIN’s attention to quality and consistency, our contact rivets run better than others in their high speed assembly operations.


We have numerous years of experience with electromechanical switches and relays. With our on-staff materials scientists, many companies depend on SAIJIN as a technical resource to assist in selecting the best contact geometry and material for each application. We also assist with cost reduction and ROHS compliance.

Our quality systems are supported by ISO 9001:2000 certification, with compliance to the automotive specific clauses of TS 16949 including PPAP, APQP, and FMEA.

In addition to contact rivets, we produce brazedwelded, and staked contacts and contact assemblies.
