ausdehnungsfähig

Ausdehnungsfähig is a German adjective that translates to "expandable," "ductile," or "pliable" in English. It describes the property of a material that can undergo significant deformation under tensile stress without fracturing. This means the material can be stretched or drawn out into a thinner wire or filament. The ability of a material to be ausdehnungsfähig is a key characteristic in many manufacturing processes, particularly those involving metalworking.

Materials that are highly ausdehnungsfähig can be subjected to processes like wire drawing, where they are pulled through a die to reduce their diameter. This property is also crucial in applications where components need to be shaped or formed, such as in the creation of sheet metal parts or the extrusion of plastic components. The extent to which a material is ausdehnungsfähig is often quantified by its elongation at break, which measures how much a sample of the material can stretch before it snaps.

Metals like gold, silver, copper, and aluminum are known for their excellent ausdehnungsfähig. Plastics and certain polymers also exhibit this property, though the range and mechanisms of expansion can differ significantly from metals. Understanding and controlling the ausdehnungsfähig of materials is essential for engineers and material scientists to select the appropriate materials for specific applications and to design effective manufacturing processes.
