Rhenium
Among the highest density element and melting point, rhenium does not have a ductile to brittle transition temperature and does not form carbides. High resistivity, combined with low vapor pressure, it is an ideal material for filament applications. Excellent resistance to corrosion, resists acid attack and the mechanical effects of electrical erosion. Rhenium has a beneficial effect as an alloying addition with other refractory metals as it greatly enhances the ductility and tensile strength of these alloys.
Rhenium Products
Ed Fagan Inc. has Rhenium sheet available from mill in a variety of sizes. Please call one of our materials experts; our sales people are very knowledgeable and can assist you with your requirements.
