Product Description Vacovit 465 Glass Sealed Alloy ribbonProduct Description4 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.Chemical Composition in %, InvarbrandChemical compositionNiCrFeCPMnBAlSiS≤4j641.5~42.55.4~0~6.3Bal0.050.020.25-0.20.30.024j4746.8~47.80.8~1.4Bal0.050.020.40--0.30.02Vacovit 46546.0~48.05.0~6.0Bal0.050.020.400.02-0.30.02 Basic physical constants and mechanical properties of the alloy: brandDensity g / cm3resistivityCurie point4j68.150.922704j478.190.55400Vacovit 4658.180.90340coefficient of linear expansionTypical expansion character(10 -6 / oC )Temperature range20~10020~20020~30020~40020~50020~55020~600Expansion coefficient9.09.08.99.610.911.4111.8 Varieties Steel type SpecificationsmmPrecisionalloyResistance Alloys for electrical heatingSuper alloyWelding wireCorrosion resistantalloyRodshot rolling rodsΦ8~38mmavailable available availableCold-drawn rods≤50mmavailable available availableForged rodsΦ38~350mmavailable available availableWiresRound wiresΦ0.3~8mmavailableavailableavailableavailableavailableNon-circle wiresNegotiationavailable available availableStripsCold rolling0.15~4×200mmavailableavailableavailable availableHot rolling4~22×200mmavailableavailableavailable availablePlatesCold rolling0.5~4×1000×2000mmavailable available availableHot rolling4~22×1000×2000mmavailable available availabletubesΦ4~63×0.5~5mm available availableExecutive standard: GB, GJB, HB, YB, ASTM, AMSE, negotiation and so on. 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.
