Default What metal are Virgo wheels made of?

I got a decently clean set with tires about a week ago for $100, but they do have some caked-on brake dust my dad and I are trying to clean up. We went to O'Reilly Auto Parts to get wheel cleaner and they had different cleaners for different metals. They're made in Germany if that helps.

They are painted forged aluminum wheels. there are some threads about wheel cleaning here.

They're painted? They felt a little rough and pitted. And I'll make sure to look up those guides.

If they have tires on, get them dismounted, yank the old stems, pull the old weights and have them media blasted. Then you can go about repairing the surface as you see fit and paint/powder coat/polish as you see fit. Gonna have to do that to my Wife's Virgos next winter.

I've had a few Virgos I swear were made from pot metal.

Cast aluminum. Complex shapes like a Virgo wheel would be near impossible to forge. The grain structure when they break tells the story. Very large grains.

Detergent 600 works the best.

All are cast aluminum. The only way to forge would be simple pancake or complex die (but you'd still have mucho machine work to do). Oh and the cost of forged wheel, like real real high. Also, once the paint is scuffed or eaten by brake dust the aluminum is very happy to corrode (pit).

They used to be made out of round cast aluminum. Now, they are not round, but still cast aluminum.

Not sure, maybe. Just dilute it a bit. I tried all types of wheel cleaners to remove baked on brake dust and none worked. This stuff did the trick even on the Volvo plastic hub caps. Spray it on, let it sit for a few minutes, scrub lightly with a mild ScotchBrite pad and rinse. Remember to dilute, maybe 1 part cleaner to 3 parts water.[IMG] photo upcloserust_zps1b029ccf.jpg[/IMG]

This. I had a few that have completely crushed lips on them.

As some other people have mentioned, Detergent 600 (concrete etching acid - active ingredient: muriatic acid) diluted with water works great for cleaning painted wheels caked with brake dust, but will eat bare aluminum and steel given time.

You should be able to find muriatic acid in some form at your local hardware store, often among paint, cleaning, or masonry supplies.

When diluting with water, add the acid to the water, slowly.

Work with gloves and in a very well ventilated area (preferably outdoors).

I mixed the solution in a bucket and applied it to the wheels with a chip brush, being careful not to splash or aerate it.

I fashioned scrapers out of wood to aid in removing the brake dust.

I hope that helps.

Ok I learned something. Virgos are cast. Thanks for correcting me.

Come on, stop pulling OP's leg. Virgos are made of Nitrogen-Carbide fiber, that's why they're black. Best way to clean them is to gently dip them in a bath (old tub works great) of sulphuric acid.

I was told by a friend that tried to have a set of Volvo wheels chrome plated that they were aluminum-magnesium alloys (or that is what the plating company told him).

You do know there are at least three grades of al-mg alloys suitable for automotive wheel casting, right?

And... Pure aluminum wheels would corode like a mofo

Edit:// A "materials engineering" book would likely have information relevant to aluminum alloy structures.
