Elcon Precision is a leading manufacturer in products formed from Kovar.  Kovar is a Nickel-Cobalt ferrous alloy designed to have a low thermal expansion coefficient.  This allows it to function effectively as a seal because even relatively extreme changes in temperature will not cause it to leak. Kovar is also highly magnetic.  It is ideal for glass-to-metal seals and for joining metal to ceramic. 

At Elcon, we take pride in the fact that we source all of our Kovar domestically.  Our over fifty years of experience and master technicians uniquely suit us to provide Kovar solutions. We aim to meet all customer-driven specifications and have the capacity to combine CNC machining and photo etching on sheets up to 2mm thick. We can etch up to 0.025 of an inch thick sheets that range up to 22x12 inches, as well as plate it in Nickel or Gold.
