Invar alloy thin wall thickness 4j29 tube
The Invar alloy thin wall thickness 4j29 tube is a low-expansion iron-nickel-cobalt alloy. The thin-walled tube of Invar alloy thin wall thickness 4j29 has an extremely low coefficient of thermal expansion as its core feature. The wall thickness is usually precisely controlled at the millimeter level, such as 0.1 to 1 mm. It combines lightweight and high dimensional stability. Through precise composition (29% nickel, 17% cobalt, the remainder being iron) and special heat treatment, Invar alloy thin wall thickness 4j29 tube maintains nearly zero expansion within a wide temperature range (-60℃ to +80℃). It is suitable for precision applications that are sensitive to temperature deformation.
The Invar alloy thin wall thickness 4j29 tube, with its ultra-low thermal expansion, is widely used in aerospace (satellite optical supports, space conduits), high-precision electronics (microwave device packaging), scientific instruments (laser resonators, telescopes), and semiconductor equipment (photolithography machine carriers). It ensures dimensional stability under extreme temperature differences. The Invar alloy thin wall thickness 4j29 tube is an indispensable key material in precision industry.
Features of Invar alloy thin wall thickness 4j29 tube
Ultra-low thermal expansion: The Invar alloy thin wall thickness 4j29 tube has a thermal expansion coefficient of only about 1.6×10⁻⁶/℃ at room temperature, much lower than ordinary metals. This effectively reduces thermal stress deformation.
High strength and fatigue resistance: The thin-walled design of the Invar alloy thin wall thickness 4j29 tube reduces weight. At the same time, cold working strengthens it to keep high mechanical strength. It has excellent fatigue resistance.
Precision machinability: The Invar alloy thin wall thickness 4j29 tube can be welded, turned, and polished. It is suitable for high-precision inner/outer diameter tolerance requirements (such as ±0.01mm).
Environmental stability: The Invar alloy thin wall thickness 4j29 tube is oxidation-resistant and has low magnetic permeability. It is suitable for vacuum or electromagnetic sensitive environments.
Applications of Invar alloy thin wall thickness 4j29 tube
Aerospace: The Invar alloy thin wall thickness 4j29 tube is used in satellite optical supports and spacecraft precision conduits. It avoids focal length shifts caused by temperature differences.
Electronics packaging: The Invar alloy thin wall thickness 4j29 tube is used in the casings of high-precision microwave devices. It ensures the stability of high-frequency signal transmission.
Scientific instruments: The Invar alloy thin wall thickness 4j29 tube is used in laser resonators and structural parts of telescopes. It eliminates temperature drift errors.
Semiconductor equipment: The Invar alloy thin wall thickness 4j29 tube is used in photolithography machine wafer carriers. It ensures nanometer-level processing positioning accuracy.
