Hi I'm looking at a set of these wheels for my 205 and was wondering does anyone know if they will be magnesium or just aluminium they are proper rally wheels as far as I know as used on group n rally cars. Is there an easy way to test what they are? the seller doesn't know and I don't want to be left with a set of very fragile and unusable on the road wheels   cheers Andy |

Good chance if they are magnesium that they would have been on the works cars only and not sold on for the very reason of cracking/fatigue .
If the seller does not know and there are no numbers codes to check out then you are either left with trying to find someone who can test them [ maybe a scrap dealer with a PMI x ray gun ] or shaving some off and seeing what is does under a gas torch !

You can tell straight away just by the weight. Magnesium wheels are ridiculously light.

Thanks for the advice ive asked the seller to weight them for me and they are fairly local so I could go do the vinegar test if the seller will let me. If they do turn put to be magnesium are they sutable to be used on a road car?
Cheers

Get them crack tested, especially if they have come off a stage car.

The sellers just weighed them for me they said the only scales they have only go up to 5kg and these exceed that so its unlikley that they are magnesium surely? Just seen a compomotive 13x6 th alloy weighs 5.5kg
