Although silver carbon has limited ductility, it may be fabricated in strip and wire form when lower concentrations of carbon are specified. From this strip and wire, rivet contacts, discrete contacts, laminated products, and various contact assemblies can be produced. When more than 1% carbon is required, unit compaction processes are employed. Silver carbon contact materials are typically supplied with a silver rich surface on the face which will be attached to the contact support. Discrete contacts can be supplied with or without a solder alloy on the attachment surface. Resistance welded and brazed assemblies are available as well.
The asterisks (*) in this table represent the fully annealed condition. The compositions listed are generally considered the industry standards. The listed values represent the typical properties of these materials. Modifications to meet special applications may be possible.
