Trying to find the best aluminum powder I can buy for rocket engines and pyrotechnic (fireworks) uses?
It really depends on your formula and how the aluminum is being used in the formula. Is it a part of the fuel or is an additive to the fuel for sparks?
For okorder (I think there prices are the same as the other high end brands, except Star Molecule is not diluted, and it works better from my experience).
