Pure Rhenium Plate

A pure rhenium plate is a flat sheet composed entirely of the rare transition metal rhenium (Re). Thanks to its exceptional resistance to high temperatures, mechanical stress, and severe corrosion, it has become a critical engineering material for meeting the demands of extreme operating conditions in cutting-edge fields such as aerospace, energy, and scientific research.

Chemical purity: Re ≥ 99.99% (calculated by subtraction, excluding gaseous elements); Complies with ASTM B775 / ISO 9001 standards.
Dimensions: Thickness (0.01–20 mm) × Width (0.5–200 mm). Customization available upon request.

Pure Rhenium Plate Heater

 

Compared to conventional heating elements, pure rhenium plate heaters not only exhibit superior electrical performance but also possess a significantly longer service life under demanding operating conditions, such as high temperatures and highly corrosive environments.

Rhenium foil

 

In the field of thin-film fabrication, rhenium foil is widely used in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes, encompassing techniques such as thermal electron-beam evaporation, low-temperature organic evaporation, Atomic Layer Deposition (ALD), and Metal-Organic Chemical Vapor Deposition (MOCVD). Additionally, it is utilized to manufacture specialized components for aerospace equipment, meeting design requirements for high precision and high reliability.

*Customization available

• High Melting Point: 3,186°C (third highest among elements), ideal for extreme heat environments.
• Density: ~21 g/cm³, providing robustness in compact forms.
• Creep Resistance: Maintains structural integrity under prolonged stress at high temperatures.
• Corrosion/Oxidation Resistance: Performs well in aggressive chemical and high-temperature oxidative environments.
• Stiffness: High modulus of elasticity, offering dimensional stability.

Multiple fields

Aerospace & Defense: Rocket engine liners, turbine blade coatings, and heat shields due to thermal stability. Satellite components require reliability in extreme conditions.

Energy & Industrial: High-temperature furnace components (e.g., heating elements, crucibles). Nuclear reactors, potentially for neutron reflectors or instrumentation.

Electronics & Imaging: X-ray tube targets (high atomic number enhances X-ray yield).

Electrical contacts in high-voltage/arc-resistant systems.

Chemical Processing: Corrosion-resistant linings for reactors handling corrosive substances.

Research & Medical: Substrates for high-temperature experiments.

Radiation therapy components (investigational use due to density and stability).

1.  Rhenium is sensitive to oxygen; it must be used in a vacuum or inert atmosphere at high temperatures. If operated in air, an oxidation-resistant coating should be applied. Additionally, contact with materials such as carbon or alumina at high temperatures must be avoided to prevent contamination through chemical reactions.
2. Electron beam welding or tungsten inert gas (TIG) welding is recommended; base material surfaces must be thoroughly cleaned and adequately protected before welding. When joining with dissimilar metals such as molybdenum or tungsten, thermal expansion compatibility must be assessed and transitional structures designed.
3. Processing rhenium plate is challenging. During cold rolling, stamping, or bending, the amount of deformation per pass must be strictly controlled and combined with intermediate annealing to prevent cracking. If specific dimensions are required, it is advisable to confirm processing feasibility with Lork in advance.
4. Rhenium is a non-magnetic metal, making it suitable for precision instruments and experimental apparatuses that are sensitive to magnetic fields.
