Invar 36 Round Bars, also known as UNS K93600, are made from a nickel-iron alloy containing 36% nickel and 64% iron. This alloy is prized for its exceptionally low coefficient of thermal expansion, which minimizes dimensional changes with temperature fluctuations.
Invar 36 Round Bars widely used in industries like electronics, aerospace, and medical technology, these bars offer superior strength, ductility, and toughness even at high temperatures up to 500°C.
Invar 36 Bars excel in applications requiring stability and precision, thanks to their excellent electrical properties and resistance to atmospheric corrosion. Ideal for components needing consistent performance over time, they are favored in precision engineering where minimal thermal expansion is crucial.
