Ductility and malleability are not always coextensive – for instance, while gold is both ductile and malleable, lead is only malleable.

Rich, Jack C. (1988). The Materials and Methods of Sculpture. Courier Dover Publications. p. 129. ISBN 0-486-25742-8.

malleable (ml--bl)
Capable of great deformation without breaking, when subject to compressive stress.

ductile (dktl)
1. Easily stretched without breaking or lowering in material strength.
I would challenge the statement that lead is not ductile. When it is drawn into wire (stretched), the wire has not lost any material strength.
Nevertheless, I will concede that INTERNET searchers show results that support opposing views.
