Check out our materials database with over common engineering materials! Metals are the most commonly used class of engineering material. The combination usually occurs through a process of melting, mixing, and cooling. The goal of alloying is to improve the properties of the base material in some desirable way. Metal alloy compositions are described in terms of the percentages of the various elements in the alloy, where the percentages are measured by weight.

Types of Metal – Pure Metals, Alloys & Their Applications

Wikipedia Read a Wikipedia article about metallic materials. Metals are made by mining ore from within the earth. Metal is then extracted out of the rocks in an extremely large scale industrial process. There are three main types of metals ferrous metals, non ferrous metals and alloys. Ferrous metals are metals that consist mostly of iron and small amounts of other elements.

THE rapid development of the social structure of the world during the past century is due, in no small measure, to improvements in communication. In certain ways we have annihilated distance completely, through the invention of telegraphs, telephones, and more recently and more wonderfully, of wireless telegraphy and telephony, and we are on the verge of another annihilation through the perfection of television. We have not yet discovered the magic carpet that will do for more material substances what these inventions have done for writing, speech, and vision. Nevertheless, transport by water is more rapid and more certain then ever before, while the motor vehicle has given us, during the last thirty years, a remarkable improvement, in rapid and reliable communication on land. The most recent and most spectacular development is that of aerial communication, which has given us a speed quite unattainable in any other form of transport. Metals are essential to the development of modern aircraft, if only for the reason that the motive power cannot be generated without their use.

In metallurgy , non-ferrous metals are metals or alloys that do not contain iron ferrite in appreciable amounts. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight e. For example, bauxite is used as flux for blast furnaces , while others such as wolframite , pyrolusite and chromite are used in making ferrous alloys. All pure metals are non-ferrous elements except iron also called ferrite, chemical symbol Fe, from the Latin ferrum , meaning "iron". Important non-ferrous metals include aluminium, copper, lead , nickel , tin , titanium and zinc, and alloys such as brass. Precious metals such as gold , silver and platinum and exotic or rare metals such as cobalt , mercury , tungsten , beryllium , bismuth , cerium , cadmium , niobium , indium , gallium , germanium , lithium , selenium , tantalum , tellurium , vanadium , and zirconium are also non-ferrous.

Alloys consist of a combination of two or more metal elements in the solid state. In engineering work, alloys, rather than pure metals, are generally used because of​.

An alloy is an admixture of metals , or a metal combined with one or more other elements. For example, combining the metallic elements gold and copper produces red gold , gold and silver becomes white gold , and silver combined with copper produces sterling silver. Combining iron with non-metallic carbon or silicon produces alloys called steel or silicon steel. The resulting mixture forms a substance with properties that often differ from those of the pure metals, such as increased strength or hardness. Unlike other substances that may contain metallic bases but do not behave as metals, such as aluminium oxide sapphire , beryllium aluminium silicate emerald or sodium chloride salt , an alloy will retain all the properties of a metal in the resulting material, such as electrical conductivity , ductility , opacity , and luster.

Non-ferrous metal

An element is the simplest form of matter that cannot be split into simpler substances or built from simpler substances by any ordinary chemical or physical method.

Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion. The best known traditional types are bronze , where tin is a significant addition, and brass , using zinc instead. Both of these are imprecise terms, having both been commonly referred to as lattens in the past.
