I'm not sure about strength, but be sure not to work it with any files or other tools you care about. It can do unpleaseant things.
That's entirely untrue. I constantly use files and other tools on aluminum.
With files the aluminum can collect in the teeth, just as other metals can, but perhaps more agressively. You always need, when using a file, to periodically clean the teeth with a file card and pick. If you can, pick up a used copy of the old Nicholson file manual "fileosophy"
With tools used under power, such as burrs and drills, it is a good idea to use oil as a lubricant. This prevents the aluminum from welding to the cutting edges. You can use a file card on your burrs to unclog them.
Grinding is somewhat different, as the aluminum can clog the grain of the wheel, and when it heats, it expands and can crack the grindstone. Again, you want to use a water based or oil based lube in copious quantities and dress the wheel often.
If the aluminum is anodized, this can cause wear on steel tools, due to the fact that it is very hard. Scraping away the anodized layer before putting the tool to the work helps. Also using carbide tools will avoid any problems.
Our entire modern world is built upon objects machined out of aluminum.
