Nickel Iron Alloy 48/ Nilo 48 (ASTM F30)

Technical Data Sheet

Alloy 48 (Nilo 48) is a nickel-iron controlled-expansion alloy containing 48% nickel. Alloy 48 (Nilo 48 coefficient of thermal expansion matches that of soft lead and soda lime glasses therefore Alloy 48's main use is for glass to metal seals in soft lead or soda lime type glasses. Alloy 48 is also used for thermostats in industrial applications up to 450°C (840°F).
