Glass Sealing Alloy Straight Wire (Fe54/Ni29/Co17) is part of Goodfellow's range of wires for sealing and joining glass. Available in 2 variations, these wires are composed of alloys with carefully controlled melting points to match different types of glass. The wires soften and form a strong vacuum-tight seal when heated to the annealing temperature of the glass. Example applications include sealing glass vacuum tubes, joining glass apparatus, and creating feedthroughs in glass containers. With the right variation, Glass Sealing Alloy Straight Wire provides an easy and reliable way to create strong seals and joints for glass components.
