What metals are car alloy wheels made from?
Car Alloy wheels are made from Aluminium Alloy, which is a blend of principally Aluminium and Silicon with various other trace elements added to give the correct mixture for strength without being too brittle. See http://www.tyresave.co.uk/alloywheels.ht… for the full technical specifications of the 2 main blends used: namely LM9 and LM25 depending on the casting process involved.
