Q:i used hf acid to clean the rails on my trailer and it left black streaks on the alluminum... uld it be the type of aluminum alloy???

Aluminum will oxidize. Not like steel though, that forms the red orange rust (iron oxide) that will eventually eat through thin steel. When aluminum oxidizes, it leaves a thin cloudy film on the surface. That's why nice new shiny diamond plate gets dull after being exposed for some time. It can be removed by some chemicals, apparently your hf acid. When the acid breaks down the cloudy oxidize layer, it may turn into a black residue. You'll be left with a clean aluminum surface that will, over time, oxidize and get that cloudy film again. It could also be waste compound of your hf acid etching the surface. Check to see whether the acid you're using will etch or clean an aluminum surface.

Q:I'm doing a project on aluminum and this is the one thing i can't find. Also will it rust, tarnish or corrode?

Aluminum is not explosive, although in the presence of a suitable oxidizing agent it can burn. It does not rust (that concept applies only to ferrous metals), but can corrode and will tarnish rapidly if a cut surface is exposed to air. The tarnish, aluminum oxide, protects the surface from further oxidation, and a process called anodizing puts a heavy oxide layer on the surface for improved protection. Aluminum is produced by electrolysis from aluminum oxide, which is dissolved in molten aluminum fluoride; a typical electrolytic pot uses a current of 5 volts at 105,000 amperes and will produce a ton of aluminum per day.
