INVAR 36 TECHNICAL INFORMATION
NILO alloy 36 (UNS K93600 & K93601/W. Nr. 1.3912), also known as INVAR 36, is a binary nickel-iron alloy containing 36% nickel. Its low thermal expansion coefficient makes it useful for a wide range of applications, including tooling for aerospace composites, standards of length, measuring tapes and gauges, precision components, and pendulum and thermostat rods. It is also used as the low expansion component in bi-metal strip, in cryogenic engineering, and for laser components. The alloy is also known for its high strength and corrosion resistance, which makes it suitable for use in demanding environments. Additionally, due to its low thermal expansion coefficient, it is used in the manufacturing of precision instruments such as clocks, watches, scientific instruments, and electronic devices.
