Question

Which of the following materials has the maximum ductility?

• A. Tungsten
• B. Iron
• C. Nickel
• D. Aluminium

Answer 1

Answer:

D. Aluminium

The property of a material by virtue of which, it can be drawn into the wire with the application tensile force is known as ductility.lt is measured as the ratio of elongation of the material at the fracture during the tensile test to the original length, expressed as a percentage.It may also be expressed as the ratio of reduction in the cross-sectional area in the fractured specimen to the original cross-section area.Example, Aluminium, Copper, mild Steel, etc
