Nilo K (For Springs)
A Nickel-Iron-Cobalt, controlled expansion alloy containing 29% Nickel. Its coefficient of expansion (which decreases with rising temperature to the inflection point), matches the expansion rate of borosilicate glasses and alumina ceramics.
Nilo K is also known as Kovar, Dilver, and Pernifer 2918.
