I don't think so. Pistons have to be wear resistant, and pure aluminum isn't. I think there is a lot of copper in them, at least when I took some to melt down...
Well, so far I have found that racing engines use silicon-aluminum alloy, such as 4032 or MS75. Also 2618, which has Copper 1.9 - 2.7 Iron 0.9 - 1.3 ...
