Page 1 of 4 - making magnalium without a gasburner - posted in Newbie Questions: hi ddudes i´m back from work now. I have got one question: is it possible to melt magnesium and aluminium in a can over a coal-fire to make a mg-al alloy??? i have heard from Magnalium that it is very brittle and easy to grind to very, vrery high mesh-sizes by hand.

The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates.
