Silver multi-layered Contact Buttons

Short Description:

NMT manufactures multi-layered button contacts. These contacts are made from a variety of materials ranging from simple alloys such as fine silver or silver- copper to more advanced alloys such as silver tin oxide, silver graphite, silver nickel.  Fine silver inlays are available for use with silver metal oxide face layers.  Copper is the core layer for conductivity.  High resistance alloy ie. steel, nickel, monel, and nickel plated steel which is used to support weldability. Alternatively, we have brazed backing to support applications in which brazing is the preferred form of attachment.

Presently sizes range from as small as 0.062″ to as large as .437″.   An array of weld projection designs are available to optimize your welding process. The choice of the base material, specification, size, and appropriate projection design can lead to a product best suited for your application.  Our technical staff is experienced with these products and may be able to help in your design process.

Product Detail


● Conserve precious metal

● Design lends itself to mechanization

● Custom patterns available to establish the best possible attachment

● In-house tooling capability

Electric contacts, as know as contacts, made of silver or silver alloy wire and copper wire by cold heading machine with machinery and physics principle.Mainly divided into two types of rivets and buttons, and used for welding and riveting automatic production, this process greatly reduced the cost throung the combination of expensive metal.

Material: Terminal/Bracket: Copper, Brass, Phosphor copper, copper nickel, beryllium copper, white copper,  Nickel, Aluminium, Iron, stainless steel, Monel, Clad metal etc.
