ECL supplies a wide range of contact assemblies produced with a number of attachment techniques. Brazed assemblies are made with furnace, induction, resistance, and torch brazing processes. Contacts can also be riveted to the contact supports. ECL produces assemblies with a wide range of contact support materials and forms. Copper and copper alloys, brasses, and steels are used in making assemblies. Supports are produced in house or purchased depending on the final assembly design. Castings, forgings, stampings, screw machine parts, cold headed parts and machined parts are all regularly used in our assembly operations.

Contact Tapes

ECL uses a unique hot bonding process to produce bimetal or trimetal overlays from which clad contact tapes are produced. ECL also uses a unique hot bonding process to produce bimetal or trimetal overlays from which clad contact tapes are produced. Form rolling of the clad overlay strips allows ECL to provide a wide range of weld projection designs and surfaces for these items.

ECL uses a unique hot bonding process to produce bimetal or trimetal overlays from which clad contact buttons are produced. Two common techniques are available at ECL to produce clad button contacts. The clad overlay strip is processed in progressive dies to produce the finished button contact, or contact blanks are subsequently formed to their final sizes in a separate operation. Because ECL utilizes both techniques to produce buttons our customers can be assured of sound advice on the design of this style of contact. Fine silver, silver copper alloys, silver-nickel and the silver metal oxide materials can all be supplied in the clad metal contact form. Button contacts are also produced by the "melt & coin" method. Fine silver and some of the silver alloys can be processed so that they adhere to the contact substrate. Subsequently they are coined to the final dimensions to provide a very simple and economical button contact.

Discrete Contacts can either be sintered or wrought. Sintered discrete contacts are available in a wide variety of materials and compositions. ECL combines refractory metals, tungsten, tungsten carbide and molybdenum with silver and or copper to produce the most rugged of power engineering materials. ECL also produces silver-carbon and silver-nickel materials through unit compaction powder metallurgy.

ECL produces discrete electrical contacts from wrought materials in a wide range of shapes and forms. Silver-cadmium oxides, silver-tin oxides, silver-nickels and other materials with high silver contents are processed through various metal working techniques to conform to customer specifications.

Throughout all types of processing, density and the material microstructures are regularly monitored to ensure products shipped meet all of the specified criteria.

Contact rivets are available in solid or bimetal construction. Bimetal rivets are an economical alternative to solid precious metal materials. Machines composite rivets are supplied either through either hot or cold bonding processes. In certain cases the rivets are supplies as brazed components. A number of styles and design features can be applied to contact rivets including tabular shanks, parabolic indents and a wide range of head to shank ratios.
