Does any one know manufacture and approximate date on this wheel? Was it called Indy wheel? Thanks Ron.
dont think those are magnesium i have 2 that look very simular id swear they are aluminum mine has ridges arouind the rim im kinda looking for 2 more 5X41/2
Thanks theses are 5- 4 3/4 chevy. I'm not positive but I think they are magnesium. What's the best way to tell? Ron
well you could try to polish a small area if it starts to resemble chrome they are aluminum magnesium is a DARK gray color another way to tell is to shave a small sliver off ofthe back of one and heat it up with a torch magnesium burns green i think... aluminum just melts
About 3 names as the mold was sold to new companies but I've never seen any magnesium ones. They came in 14" and 15" I was a collector for many years and looked at a bunch over the years. I still have a few.
A simple test to check whether a wheel is magnesium or aluminum is to test a spot with ordinary vinegar. The vinegar will interact with magnesium and fizz slightly. It will just lay on aluminum - like water. Well aged magnesium turns very dark grey, almost black. Aluminum turns, but not a lot more than the wheels in question. Charlie
The easiest way is simply the weight. At 34% lighter than aluminum, it should be very obvious just by picking up the wheel. However, the oxidation shown in your pictures is not typical of Mg. -EM
Thanks guys these turned out to be aluminum. Seller was told by his dad they were magnesium and had been been sitting in ba*****t for over 40 years. Lessen learned for me thank again your the best. Ron
