Question

Differentiate between Malleability and Ductility.​

Answer 1

Ductility has to do with tensile stress, whereas malleability deals with compressive stress. Materials such as lead are very malleable and can be hammered into shape with little chance of fracturing, but they are not ductile and will easily fracture if pulled from two opposite directions.

Answer 2

Answer:

Ductility has to do with tensile stress, whereas malleability deals with compressive stress. Materials such as leads are very malleable and can be hammered into shapes with little chance of fracturing, but they are not ductile and will easily fracture if pulled from two opposite directions...The terms ductility and malleability are often used interchangeably. They are similar in that they both refer to a metal’s ability to withstand stress without rupturing, but opposite in terms of the type of stress being applied. Ductility has to do with tensile stress, whereas malleability deals with compressive stress.

Both Terms Applied to Materials

Materials such as lead are very malleable and can be hammered into shape with little chance of fracturing, but they are not ductile and will easily fracture if pulled from two opposite directions.

Gold on the other hand is both ductile and malleable. In fact it is the most ductile and malleable of all known metals. It is said that one ounce of gold can be drawn into a wire so thin it will reach 50 miles before fracturing or be hammered and rolled into a single sheet of gold leaf covering 25 square meters.

In short, metals that are ductile or malleable are both capable of some level of plastic deformation when subjected to stress.
