When fabricating metals which need to be hermetically sealed to ceramic or glass, a highly specialized understanding of both manufacturing and science is required in order to produce a part that performs while in motion. ROMAC’s proven ability to control the expansion grades of Nickel and Cobalt Alloy Metals is the reason why hundreds of thousands of our hermetically sealed component parts are found in mission-critical products the world over.
