Product Description

Vacovit 465 Glass Sealed Alloy plate
Product Description

4 j6, 4 j47, Vacovit 465 at 20 ~ 400 degrees Celsius temperature range, with the expansion coefficient of similar soft glass, used for matching with corresponding soft glass sealing.This kind of alloy containing chromium, after oxidation treatment, the alloy surface generated very dense oxide film, combined with matrix and firm, and soft glass and invasive good.Therefore, to get the sealing side of high strength.Is an important sealing structure in electric vacuum industry material.

4 j6 alloy is glass sealed alloy FeNiCr departments on behalf of the brand.The group 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.
