Chemically, the Kovar alloy is bonded to the glass through intermediate oxide layers of nickel oxide and cobalt oxide;The bonding [TJC STEEL]strength is highly dependent on the thickness of the oxide layer.The proportion of iron oxide is lower due to the reduction of cobalt, and the presence of cobalt makes the oxide layer more likely to melt and dissolve in the molten glass.Judging by color, gray, gray-blue or taupe indicate good seal;Metallic colors indicate a lack of oxides and black indicates an overoxidized alloy, both of which will result in weak bonding. Applications Kovar alloys allow for tight mechanical connections between two materials over a range of temperatures and are suitable for glass/ceramic-metal seals in scientific equipment, as well as conductors entering glass envelopes [TJC STEEL]in electronic components such as vacuum tubes (valves), X-ray and microwave tubes, transistors, diode integrated circuits, etc. TD305B (0Cr20Ni14Si4) New Type high Silicon Austenitic Heat Resistant Stainless Steel- TJC STEEL.3/1/2021
