Rhenium Coils are a versatile product with a wide range of 29 variations available to suit many applications. These extremely thin and flexible coils can be made from pure rhenium or rhenium alloys. The ultra-high melting point and excellent high temperature strength of rhenium make these coils ideal for use in extreme environments like rocket engines, radiation detectors and furnace components. The variety of sizes and alloy compositions available allows these coils to be tailored to specific temperature, corrosion resistance and flexibility requirements. Whatever your needs, our Rhenium Coils provide the high performance and customization needed for advanced applications.
