4J6  rectangular alloy tube
4J6 rectangular alloy tube
The 4J6 has an expansion coefficient similar to the soft glass in the temperature range of 20 to 400℃. For matching and sealing with the corresponding soft glass. This kind of alloy contains chromium. After oxidation treatment, the alloy surface produces a very dense oxide film, which is strongly bound with the matrix, and has a good infiltration with soft glass. Therefore, a high-strength sealing surface can be obtained. It is an important sealing structure material in the electric vacuum industry.

Main fetures:
1, 4J6 Heat treatment system-Performance test sample of the expansion coefficient is heated to 1100℃± 20in a hydrogen atmosphere. Keep it warm for 15min, and cool it to below 200at 5lmin

2,416Form:Bar,tube ,belt,rod,wire,accept customized.

3,4J6 Smelting and casting process. Melt with a non-vacuum induction furnace, a vacuum induction furnace, or an electric arc furnace

4,Application:The 4J6 alloy is the representative sign of the Fe-Ni-cr series of glass seal alloy. The combination has been used by the aviation factory for a long time, with stable performance. It is mainly used to make various electric vacuum components, such as the anode cap of the electron beam tube. In the application, the selected glass should match the expansion coefficient of the alloy. In order to improve the sealing strength of metal and glass, the alloy is allowed to contain certain aluminum and cerium. In heat treatment, it should avoid its crystal village from asking for large, to ensure that the strip has good deep flushing performance and air tightness.
