  1. †Fraction of active aluminum in the total composites. Active aluminum content is determined from thermo-gravimetric analysis (Supplementary Fig. S3). ‡ Fraction of alumina mass in the total composites.§Fraction of oxidizer mass in the total composites. *The theoretical maximum densities (TMD) is defined as a mixture with no voids and a density equal to that of the densities of its component parts multiplied by their respective mass ratios. The ratio of fuel to oxidizer (Ø) is defined as the fuel stoichiometric coefficient.
