Disagree Turtle (not often)...all metals will burn
Repeat that aluminum dust is part of solid rocket fuel. Alu dust is also expolsive.
Anyone look up Thermite? Iron powder and alu powder.
Aluminum burns at around 7,000F. Changes from solid to liquid to vapor at that
point will burn. The alu is the fuel in solid rocket fuel and the
oxidizer is many times rubber dust mixed and suspended in some sort
of binder (think epoxy)
Gasoline and Diesel does NOT get that hot and why said earlier that there has to
be some catalyst in the flames
Must be something like magnesium or some such...then the coolant comes into
play. This kind of metal fire will be so hot and active, that it will split the
water molecules to become hydrogen gas (two) and oxygen gas (one) of the H2O
Think alloy and how lead/tin has a higher melting point, but mix them into an
alloy (solder) it will have a much lower melting point...and burn temp
Toss in electrical contribution and can see how it ignites and sustains. An arc
welder's temp is up there to burn aluminum/magnesium/steel/etc
Reason it doesn't burn with a welder...is that a whole lot of the
surface area needs to at that min temp. Doesn't happen because of
the thermal wicking of the rest of the part
Once aluminum gets there in temp...it is pretty much self sustaining as long
as it has oxygen. Hose it with H2O and it likes that, as that is where or one
other source of oxygen (H2O)
