TK41152 The iron-nickel constant expansion alloy is a series of constant 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. Its expansion coefficient and Curie point increase with the increase in nickel content. The combination gold is a sealing structure material widely used in the electric vacuum industry.
The alloy is mainly used for sealing with soft lead glass and small electronic tube leads. Zh
In the application, the selected sealing material should match the expansion coefficient of the alloy. The grain size should be controlled during heat treatment to ensure that the material has good deep-drawing properties. When using forged and rolled materials, the air tightness of the materials should be strictly checked.

| The heat treatment process | |
| Annealing for stress relief | Heated to 530~550ºC and hold 1~2 h. Cold down |
| annealing | In order to eliminate hardening, which be bring out in cold-rolled, cold drawing process. Annealing needs heated to 830~880ºC in vacuum,hold 30 min. |
| The stabilization process |
In protective media and heated to 830 ºC, hold 20min. ~ 1h, quench
Due to the stress generated by quenching, heated to 315ºC,hold 1~4h.
|
| Precautions |
Can not be hardened by heat treatment,
Surface treatment can be sandblasting, polishing or pickling. Alloy can be used 25% hydrochloric acid pickling solution at 70 ºC to clear oxidized surface
