Considering other structural requirements of infrared detector package, the welding between TC4 titanium alloy and oxygen free copper, kovar and other metals is generally not easy to achieve. In the experiment, by using vacuum brazing as the welding method and selecting Ti-Ni-Zr-Cu as solder, the test results of vacuum brazing TC4 titanium alloy with oxygen-free copper and kovar alloys were compared and analyzed. It is found that th
