Invar® 36 - Leading Edge Metals and Alloys | LEMA

Overview

With an extremely low coefficient of thermal expansion, approximately one-tenth that of carbon steel at temperatures up to 400° F, Invar® is often thought of as the material of choice for low expansion nickel alloy applications. The ability to maintain strength at very low temperatures also makes it the optimum choice for containing some liquid gasses.
