metallisches

Metallisches is the attributive form of the German adjective metallisch and describes properties or appearances that resemble metal. It is used to refer to both physical characteristics and visual impressions associated with metals. In everyday language it can describe surfaces, colours, or sensations that evoke a metallic impression.

In science and technology, metallische Bindung describes the type of chemical bonding found in metals, characterized by a lattice of positively charged ions surrounded by a sea of delocalized electrons. This bonding underpins many hallmark metal properties, including high electrical and thermal conductivity, malleability, ductility, and a distinctive luster. Metallische Eigenschaften can vary with temperature, pressure, and alloy composition.

The term is also common in mineralogy and geology, where metallischer Glanz or metallic luster denotes minerals that reflect light like polished metal. Examples include galena, pyrite, and native copper. By contrast, non-metallic surfaces may appear dull, glassy, or earthy. Observations of metallic appearance help in identifying materials and assessing surface treatments, coatings, and finishes.

Metallisches is frequently used in compound phrases such as metallische Oberfläche, metallische Legierung, or metallischer Glanz. In professional contexts, the nuance centers on resemblance to metal rather than a strict chemical designation, allowing its application across science, engineering, and description of everyday objects.
