China Invar Ni36 Invar Alloy Sheet

4j36 INVAR alloy wire Low Expansion Alloy FeNi36 wire
Classification : low coefficient of thermal expansion alloy
Application: Invar is used where high dimensional stability is required, such as precision instruments, clocks, seismic crMachinery for Garment, Shoes & Accessories Boiler & Furnace eep gauges, television shadow-mask frames, valves in motors, and antimagnetic watches. In land surveying, when first-order (high-precision) elevation leveling is to be performed, the leveling rods used are made of Invar, instead of wood, fibeTools & Hardware Stocks rglass, or other metals. Invar struts were used in some pistons to limit their thermal expansion inside their cylinders.
