Cladding of materials allows Checon to exploit the best properties of each, be it electrical conductivity, strength, low cost or suitability for making and breaking electrical contact. Additional layers can be added to the material system to support various attachment processes such as brazing or welding.
Cladding is the joining together of two or more dissimilar metals under extreme pressure to form a metallurgical bond. For example, clad electrical contacts can be used to marry the conductivity characteristics of silver or copper with the strength of ferrous materials, or for combining weld resistant materials with high conductivity carriers.
Combining different metals can achieve multiple solutions often driving cost down. Material which may have originally been composed entirely from precious metal, can be replaced with a material that only has precious metal where needed. The remaining portions of the product are often replaced with less expensive materials such as: copper, brass, nickel or steel. Cladding also offers the ability to optimize the most desirable characteristics of various metals and combine them to solve unique design challenges. These characteristics include: conductivity, rigidity, corrosion resistance, strength, wear resistances, density, form-ability and weld-ability. For example, copper clad steel combines the high electrical conductivity of copper with the rigidity of steel or the corrosion resistance of stainless steel.
As an electrical industry specialist, we clad parts ranging in size from fuse elements to thermostat control applications. Our tight tolerance rolling, slitting and tension leveling operations make these clad material systems suitable for running in high-speed presses and assembly lines. Typically produced as an overlay or inlay, these materials can be sold as strip or profiled electrical contact tapes, or they can be stamped into buttons, parts, and more complex assemblies here at Checon.
Overlay clad products are those in which the clad materials overlap one another entirely.
Inlay clad products are those in which the material to be clad is located in a grooved out portion of the base material.
Bi-layer or Tri-layer buttons are available with weldable backing and numerous welding patterns. Even custom serrated face buttons are achievable.
Custom multi-layer tapes with welding rails and radii shapes are made from Checon's in house form rolling capabilities. Call to discuss your width and profile needs.
