Glass Sealing Alloy Tube (Fe54/Ni29/Co17)

Glass Sealing Alloy Tube (Fe54/Ni29/Co17) is a range of low melting alloy materials available in tube form from Goodfellow. With over 119 variations, these alloys have properties such as low melting points, high thermal and electrical conductivity, corrosion resistance, and easy formability. They are commonly used for glass-to-metal seals in vacuum tubes, lamps, and other electrical components where a hermetic seal between glass and metal is required. The alloys wet and adhere to glass when heated, creating a vacuum-tight bond for sensitive devices. With their versatile properties and applications, Glass Sealing Alloy Tubes from Goodfellow enable innovative designs across industries.
