halibrand weels, alu or mag ?

Hi i have bought a pair of halibrand weels ( big windows)

on the weels it says halibrand 10,00x15 6,50 ff 2030A

the are bead blasted a couple a weeks ago so the look like aluminum
(but inside were the tyre is, the are dark grey)

but i think its magnesium weels

they are in a god condition

is this aluminum or magnesium weels

How about some pictures???

 

i have 3 pictures

 

ok here are one picture

 

and the other

 

and the number on the weels

 

Did Halibrand even make the universals in Mag?

 

yes the did

 

look mag to me... 4.75 & 5" uni'd to 5.5?

 

looks like mag to me.

 

They look like Mag, but here are some test's to find out for sure
1 Try the vinegar test. Drop a little bit of 5% acidity white vinegar on the back of the rim. If the vinegar bubbles, the rim is magnesium.


2 Scrape some of the finish with a razor blade. Scrape some of the finish off the back of the rim. Magnesium will appear silver in color. The cuttings or chips will be dusty or flaky. By comparison, aluminum will show a whiter color when scraped and the chips will be gummy or soft.


3 Grind the metal. If scraping is done alone, there may not be a ready comparison or frame of reference to feel confident in the test. If there is an area large enough that grinding will not ruin the appearance of the rim (this requires a small grinder, too), put on the goggles and grind the metal. Magnesium often squeals when pressure is applied, because it is a hard metal.

4 Test the density. Density is specific and constant, so any size sample will work to test density. Determine the mass of the sample in grams. Drop the sample in a beaker of water to determine the volume of the sample with a water-displacement test. Divide mass by volume. The density of magnesium is 1.74. By comparison, aluminum's density is 2.7.

5 If all else fails - throw it in a fire, if it erupts into an intense bright white flame with lots of smoke - you just lost a very expensive magnesium wheel

 

yes brandon thats right about the 4.75 & 5" uni'd to 5.5

LMAO!

 

must test the vinegar test

 

if its mag what price range are the in ?

 

yes they are bubbling with vinegar ( and turning dark grey on the spot with vinegar)

puhhh then i dont have to throw them in to the fire LOL

 

Damn it would have been one HELL of a fire!!!

 

the weels are going on a front engine dragster

 

Doesn't polished magnesium tarnish a lot quicker than aluminium if polished?

 

lol beat me to it

 

Hit it with a grinder in a not noticeable spot

 

Mag also turns dark if you let it sit in hot water...

 

no grinder for this weels

 

There mag.!!

 

thanks ron, do you now what they seeling for in this condition?

 

If they are going on your Dragster, Does it matter what the are Selling for ?

If you got them Cheap .... Be Happy

 

DE SOTO you are so right

thanks
