Pre-screen oxidiser and metal separately, then diaper together on a large sheet of paper. Do not make large batches, its critical mass is quite small.
Frightfully sensitive and brisant.
I prepare the Magnalium by ball milling -20 mesh granular material with commercial triangular Aluminia deburring media. It takes about 3 days for produce a dark grey powder that feels only ever so slightly gritty between the finger nails.
About 200 mg of this composition will produce a loud pop when ignited on a tile with blackmatch. It is ideal for reports in bottle rockets and in breaking small crossettes.
