High Quality Ferro Nickel Alloy FeNi36 /4J36 Round Rods Invar 36 Bar
1 . 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.
2 . Feature
Very low thermal expansion coefficient between -250℃ and +200℃
Good plasticity and toughness
3 . Application
Production, storage and transportation of liquefied gas
Measuring and controlling instruments with operating temperature below +200℃, such as temperature regulating devices
● helical connector bushing between metal and other materials
● bimetal and temperature controlled bimetal
● membrane frame Low shadow mask
● CRP component tempering die for aerospace industry
● satellite and missile electronic control unit framework below -200℃
● auxiliary electron tube in the laser control device electromagnetic lens
