Invar alloy seamless 4j36 tube
Invar alloy seamless 4j36 tube is a low-expansion iron-nickel alloy. Its main components are 36% nickel and 64% iron. It also has a few other elements like carbon and manganese. Invar alloy seamless 4j36 tube has a very low thermal expansion coefficient (CTE) from room temperature to about 230°C. It is almost zero-expansion. It is made by precision cold rolling or hot extrusion. It has high dimensional stability, uniform wall thickness, and a very good surface finish. It is used in places where heat deformation is a big problem.
Invar alloy seamless 4j36 tube is used in precision instruments like lasers and atomic clocks. It is also used in aerospace satellite parts such as antennas and fuel tanks. It is used in LNG low-temperature pipelines and semiconductor equipment. Its near-zero thermal expansion makes sure it stays stable in size. It can resist deformation caused by temperature changes. It is perfect for high-precision needs in tough temperature-changing environments.
Features of Invar alloy seamless 4j36 tube
Ultra-low thermal expansion: Invar alloy seamless 4j36 tube almost doesn't change size in a wide temperature range. It is good for places with big temperature changes.
High strength and fatigue resistance: The seamless structure of Invar alloy seamless 4j36 tube has no weld defects. It is stronger against pressure and mechanical stress.
Good machinability: Invar alloy seamless 4j36 tube can be turned, welded (with matching welding materials), and cold-formed. It can meet the needs of complex parts.
Corrosion and oxidation resistance: Invar alloy seamless 4j36 tube stays stable in dry and moderately corrosive environments. In extreme conditions, it needs surface treatment like plating.
Applications of Invar alloy seamless 4j36 tube
Precision instruments: Invar alloy seamless 4j36 tube is used in optical telescope supports, laser cavities, and atomic clock parts. It reduces thermal drift errors.
Aerospace: Invar alloy seamless 4j36 tube is used in satellite antenna support tubes and spacecraft fuel tanks. It can handle the extreme temperature differences in space.
