NILOALLOY K A nickel-iron-cobalt controlled-expansion alloy containing 29% nickel. Its coefficient of expansion, which decreases with rising temperature to the inflection point, matches the expansion rate of borosilicate glasses and alumina ceramics. Used for glass-to-metal seals in applications requiring high reliability or resistance to thermal shock. Examples include: high-power transmitting valves, transistor leads and headers, integrated-circuit lead frames and photography flash bulbs. STANDARD PRODUCT FORMS Pipe, tube, sheet, plate, round bar, forging stock and wire. Strip, plate and wire. MAJOR SPECIFICATIONS UNS K93600, K93601 , DIN 385, 1715 Werkstoff Nr. 1.3912 UNS K94100 ASTM F 29, F 30 DIN 385, 17745 Werkstoff Nr. 1.3917 Cold working : Cold working is not suitable for this alloy as it tends to distort the coefficients of thermal expansion. Annealing : Nilo K is used in thermostats in industrial applications up to 450°C(840°F). Applications The NILOK alloy is used in the following applications:
Semiconductor lead frames in integrated circuits Bi-metal thermostat strip Thermostat rods Ceramic-to-metal seals Glass-to-metal seals for television tubes, fluorescent lights.
