ductil

Ductil is a term that may refer to more than one concept. In English, it is most often a misspelling of the adjective ductile. It is also used as a brand or trade name by various manufacturers in different industries, with the exact meaning depending on the company and product line.

Ductile, the correct form, describes a material’s ability to undergo significant plastic deformation before fracture. This property is central to metals and some polymers, enabling drawing into wires or forming complex shapes without sudden failure. Ductility is typically measured by tests that report percent elongation or reduction of area at fracture, and it is closely related to toughness and workability. By contrast, brittle materials tend to fracture with little prior deformation.

Etymology-wise, ductile comes from the Latin word ducere, “to lead,” via ductilis, meaning “able to be drawn or led.” This reflects the material’s ability to be drawn into shapes or wires.

In commercial contexts, the name Ductil may appear on products such as hardware, piping, fittings, or metal components. As a brand, the term does not convey a single standardized specification; product properties depend on the issuing company and market.
