Not true. Years ago, Pelicanite Nick Moss contacted Fuchs directly for an answer to this question.
Q: Can you tell me what aluminium alloy was used in the Fuchs Porsche rims of the 60s and 70s?
A: We used 6082(USA), 3.2315(DIN), AlMgSi1(Type) or FUCHS Designation AS10.62,
.62 indicates Temper Disignation.
