Glass Sealing Alloy Spooled Wire (Fe54/Ni29/Co17) - Ø 0.05mm L 50m

Glass Sealing Alloy Spooled Wire (Fe54/Ni29/Co17) is designed for precision-fed applications in high-throughput glass-to-metal sealing operations. Manufactured with controlled surface roughness and dimensional consistency, this alloy wire ensures optimal wetting and bonding behavior during thermal cycling. Its Fe-Ni-Co composition is tuned to achieve thermal expansion compatibility with glass, mitigating interfacial stresses and preserving seal integrity. This wire is widely used in automated assembly of electrical feedthroughs, vacuum tubes, and lighting components, particularly where continuous wire feeding is essential. It enables high-quality seals in sensor pins, electronic enclosures, and sealed optics used in aerospace and photonic systems. The spooled configuration supports efficient integration into robotic welding stations and precision coil winding processes for high-volume production. In both scientific instrumentation and industrial device packaging, Glass Sealing Alloy Spooled Wire (Fe54/Ni29/Co17) is integral to ensuring long-term reliability, especially where performance depends on airtight, thermally matched glass-metal interfaces.
