On candle when candle flame is about 1.000 degrees celsius and melting point of aluminum is 660 degrees celsius.
Aluminium is a highly reactive metal and undergoes passivation. Thus, there is a highly non-reactive layer of Al2O3 around any piece of aluminium exposed to oxygen for any length of time. Al2O3 has a melting point of 2000+ degrees celsius, and it provides some amount of insulation to the aluminium below.
If you are using tinfoil it is because it is coated with aluminum oxide which has a melting point of 2,000 degrees celcius.
if a candle is 1000 degrees u can melt aluminum with it, it wont happen straight away, you have to give the metal a long time to heat up as it conducts heat it will take ages, you will prob let go or get bored before the metal has chance to heat up
Is it pure Aluminum ? or an Alloy of some kind ? Are you heating the aluminum in a Steel Crucible ( bowl or spoon ) of which it will absorb much of the heat and it will be difficult to achieve the proper temp for the alum to melt. Is the Flame constant, No drafts to waver the flame off Target, In theory, the aluminum should melt if held long enough by itself over a large candle flame by tongs, also, How thick is the aluminum you are trying to melt? just trying to help, I'm no expert, but thought i'd give this a shot. Good Luck Color tells us about the temperature of a candle flame. The outer core of the candle flame is light blue -- 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange and finally red. The further you reach to the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C).
www.okorder /.. its doesnt burn burn u knw.it just becomes sorta britte.it becomes oxidised...u can got more infro there.try..i read it just now
