when I was reading comics admantium was stronger than vibranium but vibranium had this unique quality with resonance and was used in a lot of sonic type devices. caps shield was made from an alloy of both that much like the experiment that created him only worked once and they have never been able to repeat it. The shield was considered much stronger than admantium and the vibranium is what allowed for its ability to bounce around. It was considered indestructible.

You and I must have been reading comics around the same time in the previous century! I recall the exact same thing, right down to the details.
