INVAR 36 per ASTM F-1684
ASTM F-1684 is an ASTM specification for Invar 36 covering Low Thermal Expansion Applications covering UNS K93603, UNS K93050, & UNS K93500.
INVAR 36 (Also known as NILO 36, Pernifer 36) is an alloy made up of 36% nickel and 64% iron. It has a low coefficient of thermal expansion, making it useful for applications where dimensional stability is required, such as in precision instruments and optical devices. It is also known for its high strength and corrosion resistance. Invar 36 is commonly used in electronic, aerospace and other high-tech industry.
Applications of INVAR 36 per ASTM F-1684
AEROSPACE
INVAR 36 is highly resistant to corrosion, making it suitable for use in aerospace applications such as aircraft and spacecraft.
ELECTRONICS
NILO 36 is used in the electrical and electronic industry as a substrate material for multilayer ceramic capacitors, lead frames for semiconductors, and as a material for microwave devices.
CRYOGENICS
NILO 36 is also used in cryogenic applications as it maintains its dimensional stability at low temperatures.
NUCLEAR
NILO 36 is used in nuclear industry as well, for applications such as fuel rod cladding, and control rod drive mechanisms.
OPTICAL
NILO 36 is used in the optical industry, particularly for the manufacturing of mirrors and lenses, due to its low coefficient of thermal expansion.
ROUND BAR
INVAR 36 Round Bar diameters range from 0.125″ to 8.00″ diameter.
