Given the higher tensile strength, cold working can initially appear to be better. However, finding a material with enough tensile strength is typically not as challenging as finding one with enough flexibility for a specific function.

Any material tested will eventually hit the elastic limit, commonly known as the point at which the tensile force causes permanent deformation. The yield strength of a material is the amount of pressure needed to drive it to this limit. A highly brittle material does not have a clear yield point because when stressed, highly brittle materials like glass or ceramics will break before they exhibit any flexibility. More brittle metals have lower yield strengths, which makes them less usable in many industries. If a metal is made so brittle that it cannot be determined where its yield point is, it is essentially useless.
