Nilo 48 (For Springs)
A Nickel-Iron, controlled expansion alloy containing 48% Nickel. Its coefficient of thermal expansion was designed to match that of soft lead and soda-lime glasses. This alloy also has a high inflection point.
Nilo 48 is also known as Invar 48 and Magnifer 50.
Nickel Base Wire for wire springs, flat springs and wire products
