Abstract : An evaluation was made of the physical properties of a newly developed low-density aluminum-ceramic material. The low density is achieved by filling a casting mold with minute hollow ceramic spheres and forcing molten aluminum into the mold. Since the hollow ceramic spheres are of low density and occupy an appreciable volume within the resulting mixture, an alluminum 'alloy' results that has about one-half the density of aluminum and is inexpensive to produce. Examination of the physical properties of this filled-aluminum material shows that it possesses sufficient integrity for use as a structural material. A comparison of its physical properties with those of magnesium K1A and aluminum A356 is presented. (Author)
