Invar Plate
What is Invar Plate?
An iron-nickel alloy with a very low thermal expansion is used to make the flat sheet known as Invar plate. This indicates that temperature changes have little effect on its size. For tools, gauges and precision parts where precise dimensions are important, this makes it perfect. High-quality Invar plates such as Invar 36, Invar 42, and Invar 49 are supplied by Parag Metal and are used in crucial field like electronics, cryogenics and aerospace. We maintain premium material for reliable performance as a reputable invar plate supplier in Mumbai.
