Product Description
The iron-nickel fixed expansion alloy is a series of fixed expansion alloys that can be matched with soft glass and ceramics with different expansion coefficients in a given temperature range by adjusting the nickel content. The expansion coefficient and Curie point increase with the increase of nickel content. This combination gold is a widely used sealing structure material in the electric vacuum industry

Grain size of Alloy52
The grain size of the alloy deep-drawing belt should not be less than level 7, and the grain size less than level 7 should not exceed 10% of the area. When the average grain size of the strip with a thickness of less than 0.13mm is estimated, the number of grains along the thickness of the strip should be no less than 8.

 

Welding performance of Alloy52
The combined gold has good welding performance and can be brazed and spot welded. The combination of gold and soft glass should be pre-oxidized before sealing.

Heat Treatment For Alloy52
(1) Stress relief annealing In order to eliminate the residual stress of parts after machining, stress relief annealing is required: 430~540℃, heat preservation 1~2h, furnace cooling or air cooling. [1]
(2) Intermediate annealing In order to eliminate the work hardening phenomenon caused by the alloy in the process of cold rolling, cold drawing and cold stamping, in order to facilitate the continued processing. The workpiece needs to be heated to 700~800℃ in a vacuum or protective atmosphere for 30~60min, then furnace cooled, air cooled or water quenched.
(3) Pre-oxidation treatment When the combined gold is used as a sealing material, it should be pre-oxidized before sealing. A uniform and dense oxide film is formed on the surface of the alloy. The parts are heated in saturated wet hydrogen at 1100°C for 30 minutes, and then oxidized in the air at about 800°C for 5-10 minutes. The weight gain of the parts should be 0.1~0.3mg/cm2
