Expansion Alloys
NILO® Alloy K W. Nr. 1.3981 UNS K94610
Description 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 are high-power transmitting valves, transistor leads and headers, integrated-circuit lead frames, and photography flash bulbs. Chemi...

Super Invar 32-5
Description Super Invar 32-5(UNS K93500), a magnetic, austenitic, solid solution alloy containing iron, nickel, and cobalt, is designed to provide minimum thermal expansion at room temperatures. This alloy also exhibits austenite stability to service temperature at least -67°F and thermal expansion properties less than those of Invar 36 alloy (36% nickel-iron) when used in the -67/203℉(-55/95°C) temperature range. Applications for Super Invar 32-5 have included structural components for suppo...

Invar, Invar 36, NILO 36 & Pernifer 36 / UNS K93600 & K93601 / W. Nr. 1.3912
Description Invar (also know as Invar 36, NILO 36, Pernifer 36 and Invar Steel) is a low expansion alloy consisting of 36% Nickel, balance Iron. Invar Alloy exhibits extremely low expansion around ambient temperatures, making Invar Alloy particularly useful in applications where minimum thermal expansion and high dimensional stability is required, such as in precision instruments like optoelectronic devices, optical and laser benches, electronics, and other kinds of scientific instruments. C...

NILO Alloy 42 / W. Nr.1.3917 / UNS K94100
Description A nickel-iron controlled-expansion alloy containing 42% nickel. It has a low and nominally constant coefficient of thermal expansion from room temperature to about 570°F (300°C). Used for semiconductor lead frames in integrated circuits, bi-metal thermostat strip, thermostat rods, for ceramic-to-metal seals with alumina ceramics, and various glass-to-metal seals such as the core of copper-clad wire for sealing into glass envelopes of electric bulbs, radio valves, television tubes,...

Alloy 52 (aka Pernifer 50, NILO 50, Glass Seal 52)
Description A controlled expansion alloy, consisting of 51% Nickel, balance Iron, used in a wide variety of electronic applications, especially for glass seals. Alloy 52 is a nickel iron alloy whose coefficient of expansion closely mirrors soft glass. Applications for this product include magnetic reed switches and seals that need controlled linear expansion to approximately 525 °C. Alloy 52 Basic Chemical Composition (Weight %) Ni 50.50 Cr 0.10 max Mn 0.60 max Si 0.30 max C 0...
