If you look at the CDA spec, it confirms it was Aluminium. I can remember CDA became the "must have" group, due to the weight saving on Record and SR and also the sexy looking (but very inefficient) Delta brakes. Campag' dropped the group, as it ate into Record sales too much. Still very desirable.
