Glass Sealing Alloy Rod (Fe54/Ni29/Co17) - D 19mm L 50mm

Glass Sealing Alloy Rod (Fe54/Ni29/Co17) provides structural versatility and exceptional thermal compatibility for applications involving direct bonding with glass. Its iron-nickel-cobalt composition is meticulously engineered to achieve a near-perfect match with the thermal expansion characteristics of borosilicate and aluminosilicate glasses, minimizing internal stress during sealing cycles. The rod format is ideal for machining, precision joining, and insert molding, making it essential in aerospace-grade connectors, vacuum-grade enclosures, and high-voltage insulators. In scientific applications, it is employed in the fabrication of hermetically sealed electrode assemblies, precision feedthrough pins, and optical fiber ferrules. The high mechanical integrity and low impurity profile of this alloy enhance bonding quality, reduce defect propagation, and support longevity in mission-critical devices. Its robust performance under repeated thermal and mechanical stress ensures reliability in nuclear sensors, deep-space instrumentation, and pressure-sealed microelectromechanical systems (MEMS). Glass Sealing Alloy Rod (Fe54/Ni29/Co17) remains pivotal in enabling precision-engineered solutions at the glass-metal interface.
