What Is Metal?
Metal is an element found in the periodic table, characterized by its special luster, malleability, and opacity. It boasts high strength, excellent electrical and thermal conductivity, and ductility. Metals can be cast, pressure-processed, welded, and shaped into various profiles or parts, including a variety of structural components. With over 100 elements in the periodic table, only a handful are considered metals, but these play crucial roles in modern technology and infrastructure due to their versatile properties and high melting points.
Generally speaking, there many types of metal, such as Ferrous Metals, Non-Ferrous Metals, Precious Metals, Alloys, specialty metals. Today, lets get to know about different types of Metal.
What Is Ferrous Metals?
Ferrous metals are characterized by their iron content, which imparts distinct properties that make them highly valuable in various applications. One of the primary characteristics of ferrous metals is their magnetic properties, which enable their use in electrical applications and magnetic devices.
