This specification covers depleted uranium in the form of castings. Primarily for use as aircraft cast counterweights where it is desirable to produce compound contours without machining and where space limitations require the use of a high-density material. Applications in oxidizing atmospheres necessitate a protective coating. Alloy covered by this specification is radioactive. All applicable rules and regulations pertaining to handling of radioactive material and all licensing provisions for use of such material should be observed. It is the sole responsibility of the user of this material to ensure familiarity with the safe and proper use of hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
