Economet Composite Rivet Contacts

Deringer's Bimetallic Economet Rivet Contact was developed to produce an economical composite contact and to overcome the limitations of other methods of manufacturing composites. Economets are precision headed at high speeds from wire on specially designed equipment.

There is no intermediate brazing material in metallurgically bonded Economets. Thus these composites perform more reliably, even at high operating temperatures, than composites produced by brazing. Backing is typically OFHC copper; facing is fine silver or silver alloy. Being mostly copper, the composite has superior thermal and electrical conductivity. Only a small percentage of the Economet contact is silver, so in many applications it becomes economically feasible to choose larger contacts that have the advantages of superior heat absorption, heat dissipation and high electrical capacity. Since the Deringer Economet is headed, it can be made at tolerances closer than can be achieved by brazing. Uniform consistency of close tolerances facilitates feeding and staking on high speed automatic assembly equipment.

Economet parts are also available with tubular shanks.
