Ductility
Videos
Ductility is the ability of a material to sustain significant plastic deformation before fracture when undergoing tension, i.e. when the relevant elastic modulus is Young's; the equivalent for deformi
Tensile test of an Al-Mg-Si alloy. The local necking and the cup and cone fracture surfaces are typical for ductile metals.
This tensile test of a nodular cast iron demonstrates low ductility.
Gold is extremely ductile. It can be drawn into a monatomic wire, and then stretched more before it breaks.
Platinum

Platinum is a chemical element; it has symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name originates from Spanis
Ductility
…to absorb mechanical overload like in an engine. Some metals that are generally described as ductile include gold Plutonium, Uranium and copper, while platinum is the most ductile of all metals in pure form. However, not all metals experience ductile failure, as some experience brittle failure instead, such…
