Difference between Ductile and brittle materials

The materials which elongates more than 5% before fracture is called ductile material otherwise brittle materials. Gold, silver, copper are typical example ductile materials and cast iron, concrete are brittle materials.

In failure theories yield strength is used for ductile materials where as ultimate strength is used for brittle materials.
