Rhenium and articles thereof; unwrought, powders, waste and scrap
HS v2022 Code: 811241
About rhenium and articles thereof; unwrought, powders, waste and scrap
HS code 811241 covers rhenium and articles made from rhenium, including unwrought rhenium, rhenium powders, and rhenium waste and scrap. Rhenium is a rare and valuable metal with unique properties that make it essential for various industrial applications. It is primarily used in the production of superalloys for high-temperature applications, such as those found in jet engines and industrial gas turbines. The rhenium industry plays a crucial role in supporting the aerospace, energy, and other high-tech sectors, contributing to the broader global economy.
Production process
Rhenium is primarily extracted as a by-product during the processing of molybdenum and copper ores. The production process typically involves roasting the ore, leaching the rhenium, and then purifying and refining the metal through various chemical and electrochemical techniques. Rhenium can also be recovered from spent catalysts and other industrial waste streams containing the metal.
Production inputs
The main inputs required for the rhenium industry include the raw materials (molybdenum and copper ores), as well as specialized equipment and machinery for the extraction, refining, and processing of the metal. Additionally, the industry relies on a skilled workforce with expertise in metallurgy, chemical processing, and advanced manufacturing techniques.
Production outputs
The primary output of the rhenium industry is the metal itself, which is then used in the production of various high-performance alloys, catalysts, and other specialized products. These rhenium-containing materials are often used in 841191 aircraft turbine engine parts and components, 840690 steam turbines and other vapor turbines, and 854389 other electrical machinery and apparatus, among other applications.
