Composition: Re Form: Disk Material: Rhenium CAS Number: 7440-15-5 Commodity: Metals Purity: 99.99% Temper: Annealed
Rhenium Disk provides exceptional high-temperature strength, corrosion resistance, and electrical conductivity in a precision-machined circular format suited for extreme-environment applications. Its disk geometry ensures uniform contact surfaces, making it ideal for use in electrical contacts, vacuum device electrodes, and precision optical mounts exposed to thermal cycling. Industries employ rhenium disks in aerospace propulsion systems, semiconductor fabrication tools, and high-vacuum instrumentation. Research applications include catalytic studies for hydrogenation reactions, high-temperature creep testing, and thin-film deposition processes requiring stable substrates. The disk’s combination of uniform geometry, refractory stability, and resistance to chemical degradation enables consistent performance in demanding engineering systems, supporting innovation across aerospace, electronics, and advanced manufacturing sectors.
