Nonferrous Metals
Nonferrous metals are materials, usually metals, that are not derived from iron. Nonferrous metals are generally more malleable and ductile than ferrous metals. Nonferrous metals are also generally nonmagnetic and have a higher resistance to corrosion than ferrous metals. The most commonly used nonferrous metals are aluminum, copper, and alloys - metals made by combining two ore more chemical elements, at least one of which must be a metal.
Nonferrous metals are used in many of the same applications as ferrous metals, but tend to be used more in applications requiring resistance to corrosion or when a nonmagnetic property is required. Nonferrous metals are also used in applications where the product must be strong but lightweight. If an application requires a dry-film lubricant, nonferrous metals are often chosen due to their ability to better retain a lubricant film.
Aluminum is the most commonly used nonferrous metal due to its low cost and lightweight properties. Aluminum is often used in applications that dont require higher strength or stiffness than the aluminum can provide. Applications of aluminum include aircraft skins, automobile parts, window frames and chemical tanks.
Copper is another commonly used nonferrous metal. It is less expensive than gold and silver and far more accessible. Copper is also highly malleable and ductile, making it an ideal choice for electrical wiring and electrical components. Copper is also used in many of the same applications as aluminum where strength and stiffness are desired. Copper is found in plumbing and electrical systems, electronics, and telecommunication.
Alloys are metals that are composed of two or more elements, at least one of which is a metal. Alloys are often stronger and finer than pure metals. Different alloys offer different properties that assist in meeting the desired goals for different products. Examples of alloys in common use are steel, brass, bronze, and silver. Steel is an alloy of iron, carbon, and small amounts of other elements. Brass is an alloy of copper and zinc. Bronze is an alloy of copper and tin. Silver is an alloy of copper and silver.
Nonferrous metals are an important part of modern society, especially in the aerospace, automotive, and electronic industries. Due to their resistance to corrosion, nonferrous metals are an excellent choice for exterior applications. Nonferrous metals are also preferred when striking a balance between strength, weight and cost is desired. Utilizing different alloys of nonferrous metals offers the best possible combination of strength, weight and costs for different applications.
Nonferrous metals are essential materials for modern technology and industry. Due to their properties, nonferrous metals are extremely useful for a wide variety of applications. From aerospace skins to plumbing systems, nonferrous metals are a key part of our everyday lives.
