Product Name: Telecommunications Industry Alloys

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:

Alloy 36 (Invar)

42 Alloy

45 Alloy
46 Alloy

47 / 50

48 & 49 Alloys

52 Alloy

Copper

101 &102 Alloys

All ASTM F15 alloy (Kovar©) and other alloy products are DFARS Compliant and also in conformance with Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010.
