TRIMETAL CONTACT

Home Our Products

TRIMETAL CONTACT consist of soft, high-conductivity, oxidation-resistant materials used as the makeup of electrical components. They are the materials in a system through which an electrical current flows; such as:

  • Relays
  • Switches
  • EDM applications
  • Circuit breakers
  • Earth leakage breakers

TRIMETAL CONTACT rivets comes in a variety of sizes. You can find options both small to extremely large, depending on your voltage requirements and usage.

TRIMETAL CONTACT MATERIAL PROPERTIES

When choosing the best TRIMETAL CONTACT for your application, it is important to keep in mind the six most important properties:

  • Conductivity
  • Size
  • Cycle Life
  • Brass
  • Current Load
  • Corrosion Resistance

HARDNESS

This measures how resistant materials are to various kinds of permanent deformations from an applied force. It is dependant on five factors:

  • Ductility
  • Elasticity
  • Plasticity
  • Toughness
  • Tensile Strength

CORROSION RESISTANCE

Corrosion resistance of electrical contacts refers to a material’s ability to resist chemical decay. Any material with little corrosion resistance will decay faster than ones with high resistance.

TRIMETAL CONTACT CONDUCTIVITY

Conductivity refers to the measure of a materials ability to conduct or carry an electric current. You will see this as a percent of a copper standard (ex: 100% International Annealed Copper Standard or IACS) Silver, which has the highest conductivity, has an IACS of 105.
