Product Description

Expansion alloy is provided with a special (minimum or constant ) linear expansion coefficient in a certain range of temperature. It is widely applied in electronic parts of electronic vacuum industry and other electronic apparatus, such as seals for soft glass or ceramic in electro-vacuum industry, anode caps, down-lead frames and other electro-vacuum components .

 

Alloy:4J29, 4J44
Availability:

Strips, Bars, Wires, Flats.

Typical characteristics:FeNiCo Glass Sealing Alloys take on a constant coefficient under -60ºC~+40OºC. They can firmly match seal in hard glass.
Applications:Co Glass Sealing Alloys are fit for manufacturing electronic vacuum apparatus such as emitting tubes, oscillators, ignition rectifiers, transistors, pipe-closers and outer casings of relay.
Standard:YB/T5235-93, Q/SYY 7-1999
