Rhenium Metal-Alloy Supplier | Eagle Alloys Corporation

Rhenium has the highest boiling point of any element and the third-highest melting point. This intense resistance to heat gives rhenium strength and stability in high-temperature applications, and prevents it from warping while in use. For this reason, rhenium is commonly used in combination with nickel and the alloys are used to build jet engines.
