Ductility can be quantified by the fracture strain, which is the engineering strain at which a test specimen fractures during a uniaxial tensile test. Another commonly used measure is the reduction of area at fracture.The ductility of steel varies depending on the alloying constituents.his tensile test of a nodular cast iron demonstrates low ductility. In materials science, ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire.

Styrene-butadiene rubber (SBR) is one of the most versatile copolymer rubber compounds. It consists of the organic compound styrene and the chemical budatiene, with the amount of budatiene usually being about three times more than the amount of styrene. SBR is a stable synthetic that is resistant to abrasion. It is used in a wide variety of products, such as automobile tires, children's toys, shoe soles and even chewing gum. This compound is produced either through ionic polymerization of a solution or as an emulsion through free radical polymerization.
