Kovar 4j29 Seamless Tube

Description Of Kovar 4j29 Seamless Tube

Kovar 4j29 Seamless Tube is an alloy precision pipe with Iron, Nickel and Cobalt as a core alloy making it suitable for high temperature, pressure and corrosion. Because of Kovar 4j29 Seamless Tubes' unique thermal expansion matching ability (4.6×10⁻⁶/℃ in 20-400℃) with glass and ceramic, Kovar 4j29 Seamless Tube serves as a fundamental material in electronics, aerospace and cryogenic engineering. The Kovar 4j29 Seamless Tube is produced in a non-vacuum induction furnace followed by precision cold working, ensuring accurate compositional control and material fabrications stabilizing carbon towards 0, given its alloyed nickel, cobalt, and iron, and ≤0.02% carbon content, obtaining guaranteed purity and stability during various processes. Advanced seamless manufacturing technology is incorporated to perfect the pipe construction to be free of joints for greater strength and dependability.

This Kovar 4j29 Seamless Tube features no welded sections, making it beneficial for thermal expansion. Kovar 4j29 Seamless Tubes' composition yields close performance to that of hard glass, allowing for reliability and enabling significantly enhanced results when sealing glass and metal. Kovar 4j29 Seamless Tube provides good mechanical properties and corrosion resistance, allowing stable work for an extended time in various harsh conditions.

Seamless rolling technology is utilized to smooth the inner and outer surfaces of Kovar 4j29 Seamless Tubes, eliminating imperfections caused by welding. Its fabrication technologies result in possessing advanced manufacturing technology, and good cold processing performance meaning it can be obtained through frosty drawing or frosty rolling and more. Various forms of welding, such as argon arc or spot welding, seam, and brazing, can be performed, proving its good welding performance.

With its superior capabilities in thermal expansion fitting, Kovar 4j29 Seamless Tubes make an invaluable contribution in high-tech industries, modern industries, and many more, providing good mechanical properties and corrosion resistance, which serve as strong materials.

Features Of Kovar 4j29 Seamless Tube

Stability in extreme environments: Kovar 4j29 Seamless Tube is capable of maintaining constant dimensions within the temperature limit of -196℃ to 650℃, tensile strength stably remains at 550MPa (in annealed state), and under quenching + tempering conditions, exceeds 800MPa, withstanding severe temperature variations and high mechanical stress. This is extensively utilized in satellite antenna waveguide structures, rocket engine sensor housings, and liquid nitrogen/helium transfer pipelines.

Excellent Corrosion Resistance: Kovar 4j29 Seamless Tube is well resistant to the erosion of chlorides, concentrated sulfuric acid (corrosion rate <0.1mm per year), and seepage of salt water, thus suitable to be used in marine equipment as well as chemical corrosive resistant pipelines.

High precision processability: Cold rolling (deformation <65%), hot rolling, and forging (at 950-1200℃), the Kovar 4j29 Seamless Tube's outer and inner surfaces are uniformly thick (tolerance ±0.05mm) and smooth, precise instruments' requirements for dimensional accuracy are stringent.

Reliable welding performance: Connection with copper, steel, and nickel is easy using brazing methods, and the resistive arc and spot welding techniques. This Kovar 4j29 Seamless Tube has a weld strength of over 75MPa under 1040℃ braze, assuring sealing on complicated structural parts.
