SOFT METAL Meaning and
Definition
-
Soft metal refers to a category of metals that possess relatively low hardness and are malleable in nature. These metals are characterized by their ability to be easily shaped, bent, and formed into different shapes without breaking or cracking. Soft metals usually exhibit low tensile strength, which makes them less resistant to deformation and more susceptible to dents or scratches.
Examples of commonly known soft metals include lead, tin, zinc, and aluminum. These metals are often used in various industrial applications where their malleability is advantageous. Soft metals can be easily melted and molded into desired forms, making them suitable for tasks such as casting, soldering, and fabrication.
The physical properties of soft metals are primarily attributed to their atomic structure. As compared to their counterparts, soft metals tend to have loosely-packed atoms and weaker metallic bonding. This arrangement makes it easier for the layers of atoms to slide past each other when external forces are applied, resulting in the characteristic malleability of these metals.
Despite their lower hardness, soft metals possess other desirable properties such as excellent thermal and electrical conductivity. These properties make them ideal for applications where heat dissipation or electrical conductivity is crucial, such as in wiring or heat sinks.
Overall, soft metals are a class of malleable metals known for their low hardness and high ductility, rendering them valuable in various industries and applications that require easy shaping, electrical conductivity, and heat dissipation.
Etymology of SOFT METAL
The etymology of the phrase "soft metal" can be understood by considering the origins of both terms.
The word "soft" originated from the Old English word "sōfte", which meant gentle or mild. Over time, the term expanded to describe something that is easily bent or lacking hardness.
The word "metal" is derived from the Latin word "metallum", which originally referred to the substance from which mines were excavated. It later began to specifically indicate substances such as gold, silver, and copper, commonly used in tools, weaponry, and decorative items due to their resistance and durability.
Combining these two terms, "soft metal" implies a malleable, easily shaped, or less rigid type of metal. It generally refers to metals with low melting points, such as lead or tin, or those that lack hardness compared to other metals such as iron or steel.
