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.

Key Features

  • Controlled coefficient of expansion (which decreases with rising temperature to the inflection point).
  • Matches the expansion rate of borosilicate glasses and alumina ceramics.

Typical Applications

Glass to metal seals in applications requiring high reliability or resistance to thermal shock, ie. high power transmitting valves.

Approx. Operating Temperature

up to +400°C
up to +750°F
