Invar 36

INVAR 36 I022

One of two low expansion metals that are used as end fittings with high temperature metal bellows seals. The other metal being Carpenter 42.

Unfortunately neither of these metals has good corrosion resistance so the sealing application is limited to high temperature non-corrosive fluids such as heat transfer oils, hot resins and plastics, along with polymers and monomers.
