Invar alloy thin wall thickness 1j29 tube
The Invar alloy thin wall thickness 1j29 tube is a precision tube made of nickel-iron based low-expansion alloy. It has a typical composition of 29%–30% nickel, ≤0.5% cobalt, and the remainder is iron. The wall thickness of the Invar alloy thin wall thickness 1j29 tube is usually controlled at the millimeter level (such as 0.1–1.0 mm). It has very high dimensional accuracy and uniformity. It is suitable for fields with strict requirements on the coefficient of thermal expansion. The Invar alloy thin wall thickness 1j29 tube is made by special cold rolling or drawing process. Its surface can be polished or coated to improve corrosion resistance.
The Invar alloy thin wall thickness 1j29 tube has very low thermal expansion. It is widely used in aerospace (satellite frames, optical components), precision instruments (lasers, telescopes), electronic packaging (semiconductor thermal management), and energy fields (LNG cryogenic components). It ensures dimensional stability under extreme temperature differences. The Invar alloy thin wall thickness 1j29 tube is a key material for high-tech equipment.
Features of Invar alloy thin wall thickness 1j29 tube
Ultra-low thermal expansion: The Invar alloy thin wall thickness 1j29 tube has a very low expansion coefficient (≤1.5×10⁻⁶/℃) from -60℃ to 80℃. It almost ignores the size changes caused by temperature.
High strength and rigidity: The thin wall of the Invar alloy thin wall thickness 1j29 tube makes it lighter. But it still has high mechanical strength by work hardening or heat treatment.
Good processability: The Invar alloy thin wall thickness 1j29 tube can be welded, bent and machined precisely. It is suitable for complex structure assembly.
Environmental stability: The Invar alloy thin wall thickness 1j29 tube is resistant to oxidation and has low sensitivity to humidity. It is suitable for vacuum or extreme environments.
Applications of Invar alloy thin wall thickness 1j29 tube
Aerospace: The Invar alloy thin wall thickness 1j29 tube is used for satellite frames and supports of optical instruments. It ensures the stability of structure size in severe temperature difference environments.
Precision instruments: The Invar alloy thin wall thickness 1j29 tube is used as the material of laser resonator and astronomical telescope tube. It reduces the influence of thermal deformation on precision.
Electronic packaging: The Invar alloy thin wall thickness 1j29 tube is used in high-precision semiconductor equipment. It isolates the interference of thermal stress on sensitive components.
Energy field: The Invar alloy thin wall thickness 1j29 tube is used as the compensation part of LNG transportation pipeline. It adapts to ultra-low temperature working conditions.
