Elcon specializes in joining ceramic to metal and metal to metal assemblies by brazing. Our brazing processes offer several advantages, including high hermiticity and repeatability with minimal part-to-part variation. Typical base materials that we braze include copper, alloy steels, molybdenum, stainless steel, and Kovar. Common applications include aerospace components, microwave-transmitting tubes, and medical components.

We typically work with active metal braze, copper, gold, and silver-based alloys. Depending on your material type and part geometry, our experienced engineers will select the appropriate brazing method to join custom components.

Through atmosphere or vacuum brazing, we join metal to metal and ceramic to metal in a controlled environment. This process protects the assemblies from oxidation. Our active metal brazing process is suited for assembling metal substrates to ceramic parts without metallization and is normally very cost effective.

As an additive value service we can join metal components by laser, TIG, or spot welding. We also offer gold, nickel, silver and copper plating services that comply with military standards (Mil Spec).

Metal to Metal Brazing Process	Is a metal-joining process where an alloy is melted and distributed between two or more metals via capillary action.
Ceramic to Metal Brazing Process	Is a metal to ceramic joining process where an alloy is melted and distributed via capillary action between a ceramic(s) that has been metallized and a metal(s).
Active Metal Brazing Process	Is a joining process which allows metal(s) to be joined to ceramic(s) without metallization.
Atmosphere Brazing Process	Is a joining process between a metal and another metal or metal(s) to a ceramic(s). It uses inert, reducing atmospheres, which protects the part from oxidation.
Vacuum Brazing Process	Is a joining process between a metal and another metal or metal(s) to a ceramic that offers significant advantages, which include extremely clean, superior, braze joints of high integrity and strength.
Partial Pressure Brazing	Is a brazing process done in a vacuum furnace wherein controlled atmospheres of inert gases (nitrogen, argon or helium) are introduced at or near brazing temperature to reduce sputtering of braze alloys.
Laser Welding Process (Added Value)	Is a joining process between multiple pieces of metal through the use of a laser. This allows for significant advantages, which include narrow, deep welds, and high welding rates.
TIG Welding Process(Added Value)	Is a joining process between multiple pieces of metal that heats via an arc of electricity jumping from a (tungsten metal) electrode to the metal surfaces you intend to weld - usually Kovar or stainless steel.
Spot Welding Process(Added Value)	Is a joining process between multiple pieces of metal, which is produced by the flow of electric current through the resistance of metals, held together under pressure.
