Nilo K (For Springs)
Nickel-Iron-Cobalt Base Wire for wire springs, flat springs and wire products
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.
- Controlled coefficient of expansion (which decreases with rising temperature to the inflection point).
- Matches the expansion rate of borosilicate glasses and alumina ceramics.
Glass to metal seals in applications requiring high reliability or resistance to thermal shock, ie. high power transmitting valves.
