Phil,
although it will probably work, as Ted noted, it may not give the best or quickest of cuts, and may deform the edges of the kerf, for sheet aluminum. Blade shape is also important, and McMaster-Carr has some great references in its online catalog about this. The variable and bi-metal blades have worked well for me as well.
The big woodworking 4TPI blades probably work quite well in thicker stock, but I dread to see how they cut thinner flat aluminum, unless the blade was running at a high speed with a low feed rate - and don't forget, al can have quite a variance in temper/hardness as well - this will all influence cutting ability. I've cut 3" al rounds in my Harbor Freight bandsaw with 12TPI blades, and found that it cut better and cleaner with squirts of WD-40 - removes the swarf and helps to stop the blades getting hot. I've only used cutting fluids when drilling/tapping/milling/turning aluminum ,and for the noted thicker bandsaw cuts.
Read a good bandsaw handbook to find expert opinion. Not to say other blades won't work, but if you're looking for the optimum....
