A cast reactive metal body that can be used as weapon cases is offered. It is cast with aluminum or aluminum alloys with small particles and/or fibers of metals of high density such as molybdenum, tungsten or hafnium. Aluminum alloys are those that can get easily ignited when heated and burn fast afterwards in particulate forms. Metals that react intermetallically with aluminum are excluded. The particles and fibers are of the size between a few microns and a few hundreds of microns in diameter. The length of the fibers is longer than the diameter. The weight percentage of aluminum and/or aluminum alloys range from 10 to 90 percent and the weight percentage of heavy metal particles/fibers ranges from 90 to 10 percent. Other inert materials such as ceramic particles can be added in small amounts.
