Used in aerospace and automotive industries for lightweight, high-strength components due to excellent mechanical and thermal stability. Commonly found in seals, bearings, and piston parts exposed to high temperatures and harsh chemicals. Widely adopted in medical implants, such as spinal devices, because of its biocompatibility and resistance to sterilization processes. Employed in oil and gas equipment for downhole tools and seals that withstand extreme environments. Also used in semiconductor manufacturing and electrical insulation where purity and performance under heat are critical.
