Alloys Used in the Telecommunications Industry |Kovar, Invar, 42 Alloy

Telecommunications Industry Alloys

ASTM F15  ALLOY (KOVAR) is the primary alloy used in the telecommunications  industry.

ASTM F15 ALLOY (KOVAR) is the primary alloy used in the telecommunications industry.  ASTM F15 ALLOY (KOVAR) provides a stable environment and enables optimal performance in high frequency fiber optic cables and tubes that are used for voice, video and internet data transmissions. This controlled expansion alloy is used to create metal-to-glass hermetic seals that allow electrical currents to enter sensitive electronic devices while protecting those devices from the outside environment.


Common applications for ASTM F15 (Kovar) alloy in telecommunications and fiber optics include WADM (Wavelength Add/Drop Multiplexer) modules, modulators, attenuators, integrated and hybrid circuits, image sensors, pump lasers, transistors, switches and amplifiers.

In addition to ASTM F15 (Kovar), the following Nickel-Iron alloys with low and/or controlled expansion rates are used in the telecommunications industry:
