Product Description
4J6 Fe-Ni-Cr Glass Sealed Alloy Plate
4J6 is a typical glass sealing alloy, the coefficient of expansion is similar to the soft glass in the temperature range of 20~400℃. The alloy contains 6% chromium, and after oxidation treatment the alloy surface produces a very dense oxide membrane that is strongly bound to the substrate and well infiltrated with the soft glass, so that can get high strength sealing surface.
The alloy is an important sealing structure material in the electric vacuum industry, In addition, the alloy contains 42% nickel, that is why the US label is called 42Ni-6Cr (Glass sealing 42-6, UNSK94760).American Carpenter also produced the alloy that called Carpenter 42-6.

Application
4J6 alloy is glass sealed alloy FeNiCr departments on behalf of the brand.The alloy via air factory use for a long time, stable performance.Mainly used for making all kinds of electric vacuum components, such as electronic tube anode caps, etc.That should be chosen in the application of matching expansion coefficient of glass and metal.In order to improve the sealing strength of metal and glass allows alloy containing aluminum, cerium.When the heat treatment, grain size is too big, should be avoided to ensure the strip with good deep drawing extension performance and air tightness.
The available forms
Stip,Rod,pipe ,plate, tube and so on.
Our 4J6 precision strips were exported to the United States to a well-known air headphones and hearing aid manufacturer. The product quality was won the trust of international customers.
