Alloy , metallic substance composed of two or more elements, as either a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon , a nonmetal , is an essential constituent of steel. Alloys are usually produced by melting the mixture of ingredients. The value of alloys was discovered in very ancient times; brass copper and zinc and bronze copper and tin were especially important. Today, the most important are the alloy steels, broadly defined as steels containing significant amounts of elements other than iron and carbon.

Common-Alloys

Alloy plays a very important role in our daily life. In fact without using an alloy one day is also not passed. Utensils in the kitchen, vehicles, mobile phones etc are various alloys which are being used and made by human. Even most of the machinery tools and engineering equipments are made up of alloys. An alloy is a metallic intimately mixed solid mixture of two or more different elements, at least one of which is metal. In molten state alloys are homogeneous and in solid state they may be homogeneous or heterogeneous.

Role of Chemistry in Human Life. Metal Alloys have both physical and chemical properties together with mechanical. Some properties are reactivity, electrical conductivity, thermal conductivity, good tensile strength, resistance to deformation, malleability etc. Here, we have seen some important alloys and their uses. But the question arises, how alloys are formed , how metals are mixed etc. Traditionally it was done by heating and melting metal and converts it into liquids, mixes them and then allows them to cool to solidify it.

But some more methods are also there like powder metallurgy ; in this method, turn the components of alloys into powders, mix them together and then fuse them with a combination of high pressure and high temperature. Another method to make an alloy is Ion implantation, which is done with the help of semiconductors used in electronic circuits and computer chips. Also, an alloy in which one of the components is mercury is known as amalgam and in alloys the chemical properties of the component elements are retained but certain physical properties are improved.

An alloy is a mixture or metallic-solid solution composed of two or more elements. Examples of alloys include materials such as brass, pewter, phosphor bronze, amalgam, and steel. Complete solid solution alloys give single solid phase microstructure. Partial solutions give two or more phases that may or may not be homogeneous in distribution, depending on thermal history. Alloy constituents are usually measured by mass. An alloy is usually classified as either substitutional or interstitial, depending on its atomic arrangement. In a substitutional alloy, the atoms from each element can occupy the same sites as their counterpart.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4. Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron Fe alloyed with carbon C about 0. However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon.


Its properties are significantly different from the pure metals, copper and tin. This chapter describes how the lessons of the ancient alloys, bronze and steel.

Types of Nickel Alloys

First discovered and isolated by Axel Fredrik Cronstedt, a Swedish chemist and mineralogist, nickel exhibits several desirable properties that render it useful in industrial applications. For one, nickel is highly ductile and is valuable as an alloying element to alter the properties of other metals. For example, grades of stainless steel can be created by the addition of nickel to produce alloys that offer corrosion resistance and high-temperature endurance, making them ideal for uses in chemical plants where exposure to caustic substances may be expected.

When we polish metals, they are also good reflectors of light. Standardization in the field of corrosion of metals and alloys including corrosion test methods, corrosion prevention methods and corrosion control engineering life cycle. Commercial metal alloys attempt to combine these beneficial properties in order to create metals more useful for particular applications than any of their component elements. Fundamentals of Creep in Metals and Alloys. Solder is an alloy of tin and lead and has a lower melting point than its constituent metals, thus can be used to join metals. This is an alphabetical list of alloys grouped according to base metal.
