Mostly -20+60 mesh
, splatters, needles, and spheroidal powder
Very coarse aluminum useful for large devices such as dripping comets and fountains.
Great for slowing down thermite reactions. Simply replace 10-50% of the fine thermite grade aluminum
with coarse spheroidal to adjust the burn speed. The more you add the slower the reaction but also the harder it will be to ignite.
