The level to which materials can be deformed without breaking is known as ductility which is an aspect of plasticity. Metals can be deformed under tensile stress or applying force by pulling the piece of metal in opposite directions. The extent to which the metal will be pulled and deformed without breaking determines its ductility. Ductility is important to ensure the right materials are sourced, especially in the manufacturing of wire and nails.
There are different types of conductivity which include electrical, thermal, hydraulic and ionic, among others. Conductivity refers to the ability of a material to allow movement or passage of the associated substance (electricity, heat, water and ions). Using electricity for example, metals are known to conduct electricity, but to varied extents, with some being very good conductors while others are poor conductors. Thus metals generally allow movement of electricity from one point to another.
Conductivity describes the capacity of a metal to conduct heat and electricity
Ductility describes the tendency of a metal to be drawn into wires. All metals are good conductors of heat and electricity. Copper is the most ductile metal.
