fundidas

Fundidas is the feminine plural form of the Spanish adjective fundido and of the past participle of the verb fundir. In general usage, fundidas describes something that has been melted, fused, or cast.

In metallurgy and manufacturing, the term fundidas is commonly used to refer to metal castings, or parts produced by the fundición process. This process involves melting a metal alloy and pouring it into a mold where it cools and solidifies into a predefined shape. Castings can be made from iron, steel, aluminum, brass, bronze, and other alloys. The quality and properties of fundidas depend on factors such as alloy composition, mold material, cooling rate, and finishing operations applied after casting.

Apart from its technical sense, fundidas functions as the feminine plural of fundido in everyday Spanish, agreeing with feminine plural nouns such as piezas fundidas. It can be used in phrases describing objects that have undergone melting or fusion, for example, piezas fundidas de aluminio.

In addition to its linguistic use, fundidas may appear as a surname or place name in some contexts, though it is uncommon and not widely recognized as a major toponym or family name. Overall, the term is most frequently encountered in industrial and technical writing related to metalworking and casting.
