Alloy 42, also know as Pernifer 42, NILO 42, Glass-Seal 42, is a Nickel Iron controlled expansion alloy with 42% Nickel, and the remaining balance Iron. Alloy 42 is used in a wide variety of electronic applications, lead frames, especially for glass and ceramic seals. (read more)

Invar Sheet (Invar 36, NILO 36, Pernifer 36, Invar Steel) in many thicknesses from .020" to .125" for immediate shipment. Low expansion alloy 36% Nickel, bal. Iron, has extremely low expansion at ambient temperatures, making it very useful in minimum thermal expansion/high dimensional stability applications e.g. precision instruments optoelectronic devices, optical/laser benches, etc. (read more)

Invar alloy (also know as Invar 36, NILO 36, Pernifer 36, & Invar Steel) is a low expansion alloy consisting of 36% Nickel, balance Iron. Invar exhibits extremely low expansion around ambient temperatures, making Invar Alloy particularly useful in applications where minimum thermal expansion and high dimensional stability is required such as in precision and scientific instruments.
