Kovar 4j28 Seamless Tube

Description Of Kovar 4j28 Seamless Tube

The core components of the Kovar 4j28 Seamless Tube are cobalt, nickel, iron and makes it a seamless precision alloy pipe. Kovar 4j28 Seamless Tube has wide applications in electronic packaging, the aerospace industry and deep cold engineering. Kovar 4J28 is critical in the aforementioned industry due to its exceptional thermal expansion capabilities and performance advantages expansion properties. In addition, precision cold working and vacuum melding techniques are employed during its manufacture which makes certain, that ratios of alloy's components are like: 29% nickel, 17% cobalt, and 27%-29% chromium. This enables an alloy expansion coefficient of 4.7×10⁶/℃ for borosilicate glass from 20 to 450 degrees celsius. That means Kovar 4j28 Seamless Tube can still maintain stable seals with ceramics or glass when temperature changes occur, which greatly enhances device reliability.

The Kovar 4j28 Seamless Tube processes with cold rolling + cold drawing takes the pipe's inner and outer walls finish and constancy of wall thickness (with tolerance within ±0.05mm) to a new level. Kovar 4j28 Seamless Tube allows for numerous welding methods, ranging from argon-arc to electron beam welding. Testing corroborates the strength of the welded joint surpasses 75MPa (brazing at 1040℃). All batches of the Kovar 4j28 Seamless Tubes undergo ultrasonic flaw detection along with an air-tightness test (leakage capped at ≤ 0.0mL/min with a 60kPa pressure difference) to ensure extreme long-term stability under harsh working conditions.

Taking material science as the base,  Kovar 4j28 Seamless Tube merges precision manufacturing with reliability design for ultra-high-precision seamless pipe smooth technologies and shifting -270℃ ultra-low temperatures to 450℃ high-precision fields. Kovar 4j28 Seamless Tube serves as an irreplaceable fundamental component in modern industries.
