There are several materials and alloys that are used in creating contact materials in electrical contacts, which are both meant to help construct electrically conductive connective materials. Here are some different alloy materials used in constructing electrical contacts.

Refractory Contacts

Refractory contacts are important in helping conduct electrical current through strategic placement in devices. The necessary conductivity and resistance help determine just what materials should be chosen for your product. The following are materials used to create refractory electrical contacts:

  • Silver tungsten
  • Silver Tungsten Carbide
  • Silver Graphite
  • Silver Tungsten Graphite Carbide
  • Copper Tungsten
Buttons

In successful electrical contacts manufacturing, buttons help your finished product be as effective as possible. The following are alloys used in the composition of creating both single buttons and multi-layer buttons:

  • Silver Cadmium Oxide
  • Silver Tin Oxide
  • Silver Nickel
  • Silver Alloy
  • Copper and Copper Alloy
  • Steel and Nickel Monel
  • Braze Alloy
Rivets

Rivets are created with the distinct purpose of extending that conductivity. The materials used and how they are constructed need to target the specific construction needs of the end-result product. The following are types of rivets that are manufactured to serve electrical contacts:

  • Construction
    • Solid
    • Multi-Layer
    • Head and Shank
      • Straight Side
      • Chamfer Side
      • Step Side
      • Indent
      • Chamfer
      • Riveted Assemblies
Surface Features and Shapes

Varied shapes serve distinct purposes for the benefit of your products. The following alloy distinctions can help make a more intuitive design that enables a more efficiency and resiliency. Here are some characteristics that can be expected:

  • Knurl and Score Lines
    • For Backing Designations
    • Projections
      • For Welding
      • Nibs
        • For Locating on the Substrate
        • Serrations
          • For Desired Performance
          • Shapes
              • Square
              • Rectangular
              • Circular
              • Washer
              • Cylindrical
              • Spherical

            There are a wide range of metals that are used in making electrical contacts. In order to create a manufacturing plan best suited to your product, it doesn’t hurt to consult with an electrical contacts manufacturer to learn more.
