What is the difference between an alloy and a compound?

What more is there to say!?!?!
Answers:
An alloy is a combination or two or more elements in solution or in compound, one of which must be a metal, and where the resulting material has metallic properties.

A compound is any chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition.
an alloy is formed from a physical mixture of two or more substances ....a compound is formed from a chemical reaction
An alloy refers to metals. A compound is a substance of many different elements.
An alloy is a combination, either in solution or compound, of two or more elements, at least one of which is a metal, and where the resulting material has metallic properties. An alloy with two components is called a binary alloy; one with three is a ternary alloy; one with four is a quaternary alloy. The resulting metallic substance generally has properties significantly different from those of its components.


Steel is a metal alloy whose major component is iron, with carbon content between 0.02% and 1.7% by weight.Alloys are usually designed to have properties that are more desirable than those of their components. For instance, steel is stronger than iron, one of its main elements. It 'inherits' some of the characteristics of the elements it was made from, usually physical properties like density, reactivity and electrical and thermal conductivity. However, its engineering properties (Tensile strength, Young's modulus, shear strength) can be vastly different from its constituent materials

A chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition. The ratio of each element is usually expressed by chemical formula. For example, water (H2O) is a compound consisting of two hydrogen atoms bonded to an oxygen atom.

The atoms within a compound can be held together by a variety of interactions, ranging from covalent bonds to electrostatic forces in ionic bonds. A continuum of bond polarities exist between the purely covalent bond (as in H2) and ionic bonds. For example H2O is held together by polar covalent bonds. Sodium chloride is an example of an ionic compound.
a compound is a substance consisting of two or more chemically bonded elements. e.g. water.

an alloy is a metallic substance consisting of two or more combined elements, at least one of which is a metal. e.g. steel. They can be chemically bonded or just mixed.

So an alloy can be a compound, so sometimes there is no difference between the two. ;)
A compound can not be separed into its components by physical methods.

An alloy can. An alloy is a mixture, a compound is not a mixture.
an alloy is made from two metals a compund is where my car is
An alloy is a mixture (of a metal with one or more other metals or even non metals) and the proportions of the ingredients are variable. A compound is a substance made up of two or more elements combined chemically in proportions that never vary - no matter how the compound is made.
A chemical compound is a substance consisting of two or more chemical elements that are chemically combined in fixed proportions. The ratio of each element is usually expressed by chemical formula. For example, water (H2O) is a compound consisting of two hydrogen atoms bonded to an oxygen atom.

It 'inherits' some of the characteristics of the elements it was made from, usually physical properties like density, reactivity and electrical and thermal conductivity. However, its engineering properties (Tensile strength, Young's modulus, shear strength) can be vastly different from its constituent materials. Among other factors, this is due to the differing sizes of the atoms in the alloy - larger atoms exert a compressive force on neighbouring atoms, and smaller atoms will exert a tensile force on their neighbours. Unlike a pure metal, where the atoms are more free to move, this helps the alloy resist deformation.
