Invar Coil is an alloy composed of iron and nickel. It has a very low coefficient of thermal expansion (CTE), making it ideal for use in applications where temperature-induced changes in size must be minimized, such as bi-metallic thermometers, clock pendulums, and scientific instruments. The combination of elements gives the metal greater strength at low temperatures than pure iron. It also exhibits high levels of flexibility, good electrical conductivity and corrosion resistance.
Invar Coil is a metal alloy containing iron, nickel and cobalt. Its unique properties are its low thermal expansion rate, low thermal conductivity and strength. It is highly resistant to corrosion and wears well under repeated movements, making it perfect for use in precise machinery parts such as transformers that need to maintain accuracy over time. Additionally, Invar Coil has excellent electrical properties - perfect for electrical components or appliances where stability against changes in temperature or voltage is important.
