An alloy is a mixture of Irons or a mixture of a ore and another components. Alloys are explain by a metallic bonding character. An alloy may be a hard results of metal elements or a combination of metallic phases . Intermetallic compounds are alloys with a defined stoichiometry and crystal structure. Zintl phases are also sometimes considered alloys depending on bond types ..
Alloys are used in a wide variety of request . In some occasion, a mixture of metals may reduce the general cost of the material while maintain important properties. In other occasion, the mixtures of metals relate synergistic stuff to the constituent metal elements such as corrosion resistance or mechanical strength. Examples of alloys are steel, solder, brass, pewter, duralumin, bronze and amalgams.
The alloy component are usually constant by mass. Alloys are usually categorize as substitutional or interstitial alloys, depending on the atomic agreement that formation the alloy. They can be further classified as homogeneous, or heterogeneous & etc.
