Does anyone know what the metal composition is for the CD91 rims? Are they aluminum or some magnesium mix?

I did a search, but didn't see anyone mention the alloy type.

Thanks!
 
For the CD91, Histowheels.com says "alloy," which to them means an aluminum alloy. Wheels known to be a magnesium alloy are listed as "magnesium".

Also, a comparison of weights listed at histowheels.com confirms the above. CD30 and CD91 are similarly styled wheels but slightly different widths, the CD30 is 5.5 and the CD91 is 5.0. CD30 is shown as "magnesium" and listed at 3.8kg while the CD91 is shown as "alloy" and listed as 5.3kg.
