In pyrotechnics we use an alloy of 50:50 magnesium / aluminium called magnalium, this is a very brittle material that is very useful in fireworks manufacture. I would like to attempt to manufacture some and wondered what might the best way to go about it.
My idea is to take a cast iron pot with lid, place equal amounts of metal within, and then put the pot on an enclosed kettle bbq with a good charcoal fire built around it. To increase airflow I was thinking perhaps something along the lines of a leaf blower or hair dryer connected to the bbq air vent. I'm confident that the metals should mix sufficiently by themselves assuming they reach melting point. Accuracy is not too important for these purposes.
Reckon this sounds viable on a backgarden scale with limited budget?
