Sometimes it's handy to be able to 'tin' or solder to aluminum.  The way to establish a solder base on aluminum is to scratch/roughen the area to be tinned with coarse steel wool or sandpaper, then immediately coat the area with 30 SAE motor oil.  Then use a large soldering gun or iron on its hottest setting and 'tin' the aluminum 'through the oil' using any good quality large gauge wire solder with built-in flux.  This process smokes and stinks so do it outside or in a well ventilated area. 

The reason this does work is because aluminum oxidizes almost instantly after it is shined, roughened, or scratched.  Solder will not bond to oxidized aluminum but will to the just scratched up and oil coated area.
