Description

An alloy is a mixture of metals or a metal combined with one or more other elements. The combination of carbon iron or non-metallic silicone produces alloys called steel or silicone steel. The resulting mixture constitutes a substance with properties that often differ from those of pure metals, such as greater strength or hardness. Unlike other substances that can contain metal bases, but do not behave like metals, such as aluminum oxide (sapphire), the aluminum silicate of the beryllium (emerald) or sodium chloride (salt), an alloy will keep all the properties of a metal in the resulting material, such as electrical conductivity, ductility, opacity and brightness. Alloys are used in a wide variety of applications from steel alloys, used throughout, from buildings to cars to surgical utensils, up to exotic titanium alloys used in the aerospace industry, to the balloon alloys for beryllium copper alloys for non-sparking tools. In some cases, a combination of metals can reduce the total cost of the material by preserving important properties.

In other cases, the combination of metals gives synergistic properties to the constituent metal elements, such as corrosion resistance or mechanical strength. Examples of alloys are steel, welding, brass, pewter, duralumin, bronze and amalgam. An alloy can be a solid solution of metal elements or a mixture of metal phases (two or more solutions, forming a microstructure of different crystals inside the metal). Intermetallic compounds are alloys with a defined stoichiometry and a crystal structure. The phases of zintl are also sometimes considered alloys depending on the types of ties. Alloys are defined by a metal character of the Union. The constituents of the alloy are generally measured by the mass percentage for practical applications and at the atomic fraction for basic science studios. Alloys are generally classified as interstitial substitutions or alloys, depending on the atomic agreement that forms the alloy. They can be classified even more as homogeneous (consisting of a phase), or heterogeneous (consisting of two or more phases) or intermetallic.

An alloy is a mixture of chemical elements, which constitutes an impure substance that preserves the characteristics of a metal. It is different from an impure metal in which, with an alloy, the aggregated elements are well controlled to produce desirable properties, while impure metals, such as wrought iron, are less controlled, but are often considered useful. Alloys are obtained from a mixture of two or more elements, at least one of which is a metal. This is generally called main metal or metal base and the name of this metal can also be the name of the alloy. The other components can or cannot be metals, but when mixed with the melted base, they will be soluble and dissolved in the mixture. The mechanical properties of alloys will often be different from those of their individual components. A metal that is normally very soft, as aluminum can be modified ensuring other soft metals, such as copper. Although both metals are very soft and ductile, the resulting aluminum alloy will have a much greater force. Adding a small amount of nonmetallic iron carbon exchange its great ductility for the increased resistance of an alloy called steel. Because of its high resistance, but still substantial, and its ability to be largely modified by heat treatment, steel is one of the most useful and common alloys in modern use.
