Kovar 4j33 Seamless Tube

Description Of Kovar 4j33 Seamless Tube

Core advantages of Kovar 4j33 Seamless Tube, an iron-nickel cobalt-based low-expansion alloy seamless pipe, lie in its unique thermal matching performance and mechanical properties. By controlling the ratio of nickel (32.1%-33.6%), cobalt (14.0%-15.2%), and iron elements, the alloy achieves a linear expansion coefficient almost equal to 95% alumina ceramic (Al₂O₃) from -60 to 600 degrees centigrade (grade 6.0-8.5×10⁻⁶/℃ between 20-600℃). This characteristic makes it remarkable in the industry of sealing ceramics and metals. After being kept at 900±20 degree centigrade for 1 hour under hydrogen protection, the Kovar 4j33 Seamless Tube is slowly cooled to below 200 degrees centigrade to ensure the stability of the structure and deep drawing processing performance. The Kovar 4j33 Seamless Tube adopts a special heat treatment process.

With a density of 8.27g/cm³, the Kovar 4j33 Seamless Tube has three major technical advantages: Firstly, its low expansion characteristics effectively resist sealing failure due to thermal stress in optic tubes, electron tube magnetrons, and other precision parts that experience extreme temperature fluctuations. Secondly, superb air tightness with a melting point of 1450°C ensures long-term reliability under high pressure environments.At last, good cold processing performance assists in the manufacturing of a wide range of specifications from Φ6mm to Φ530mm with a wall thickness of 0.5-50mm, fulfilling the requirements of different packaging structures. Subset Uses include glass Kovar X-ray tube sealing, integrated circuit ceramic housing dielectric headers, and high-temperature sensors in petrochemicals, which are strategically important for aerospace, energy,y and semiconductor industries.

Features Of Kovar 4j33 Seamless Tube

Small thermal expansion coefficient: The coefficient of expansion for Kovar 4j33 Seamless Tube is approximately that for hard glass. This means it can seal glass and metals reliably and stably, thus preserving good interface matching, which safeguards the integrity and stability of the seal.

Exceptional corrosion resistance: As noted previously, Kovar 4j33 Seamless Tubes have notable advantages like outstanding long-term durability and marked resistance to a multitude of harsh conditions. This level of versatility makes them suitable for use in chemicals, equipment such as reactors, storage tanks, pumps, and valves.

Custom seamless technology: Kovar 4j33 Seamless Tubes are produced with advanced smooth-bore technologies, which ensure uniformity of the pipe's inner and outer surfaces. Such characteristics enhance the reliability and integrity of the pipe by removing non-welded defects traditionally caused by the welding process.

Applications Of Kovar 4j33 Seamless Tube

Kovar 4j33 Seamless Tubes are used to manufacture packing shells of integrated circuits, packing materials for transistors, and electron tubes. Due to a good match with the thermal expansion coefficients of glass and ceramics, Kovar 4j33 Seamless Tube provides sealing reliability and effective performance of these components when assembled. Kovar 4j33 Seamless Tubes are used in the case of filters, resonators, and other components working in high-frequency and microwave devices, which improves the signal processing due to excellent magnetic conductivity, thermal stability, and the performance of the unit. Kovar 4j33 Seamless Tubes are used to make containers and pipelines that are subjected to high temperatures and pressures. Due to its excellent corrosion resistance and high temperature resistance, Kovar 4j33 Seamless Tube can effectively resist the erosion of the medium on the material.
