Invar alloy thin wall thickness 4j36 tube
The Invar alloy thin wall thickness 4j36 tube is a low-expansion iron-nickel alloy. It has about 36% nickel. It is famous for its very low thermal expansion coefficient (CTE) in a wide temperature range from -200°C to +200°C. The Invar alloy thin wall thickness 4j36 tube (wall thickness of 0.1–1.0 mm) is made by precision cold rolling or drawing. It has high dimensional stability, light weight, and excellent machinability. It is used in precision fields that are sensitive to thermal deformation.
The Invar alloy thin wall thickness 4j36 tube is widely used in aerospace (satellite frames, optical components), precision instruments (laser cavities, atomic clocks), semiconductor mask frames, LNG cryogenic pipelines, and scientific research equipment (particle accelerators). It has almost no thermal deformation. This ensures dimensional stability and system reliability in extreme temperature conditions.
