Our tungsten alloys are used for radioactive source containers, gamma radiography, shields, and source holders for oil-well, logging, and industrial instrumentation. High-density alloys also serve as collimators and radiation shielding in cancer therapy, as well as syringe protection for radioactive injections. When you need to direct a specific amount of radiation to a targeted area, tungsten alloys provide the control you need. Luke's  Metals’ high-density alloys will continue to perform, even under extreme, high-heat conditions.
