You cannot count it in BTU in that way, it is not about how much heat, but about temperature.
You can have a billion BTU, if the temperature of that heat is at 200 degree, nothing would ever melt. Likewise, you can have just a few BTU at 1000 degrees, and you would melt aluminium; but the other important aspect is how much aluminium?
So, to answer the question, we'd have to know how much aluminium, and what is producing that heat (or at what temperature the BTU are released).

The amount of BTUs would vary depending on:
The purity of the aluminum,
The amount of aluminum you want to melt,
The initial temperature of the aluminum.

It's specific heat capacity * mass * temperature change to melt + specific heat of melting * mass. Look it up.
