Well, firstly, you should bear in mind that, the 4 main reasons for making alloys are:
1) To improve the strength and hardness of metals,
2) To lower the melting point of the metal,
3) To improve the appearance of the metal and,
4) To improve the resistance of metals against rusting and corrosion.
Now, answering the question is much easier for, keeping in your head what is in the above, we can say that:
a) Alloys are designed to have properties that are more desirable than those of the elements they contain.
b) Properties such as strength and corrosion resistance may be considerably greater for an alloy than those of the elements they contain.
This is why alloys are more widely used than pure metals.
because an alloy is two metals combined while a metal is just itself. An alloy could be potassium and gold. Let's use melting points as an example, they have two completely different melting points and they are together so there traits will blend. When they're apart their melting points will be completely different.
Alloy preparation done by adding molten metal in another molten metal or by dopping.
When we consider dopping ,It is a process of adding some foreign material in crystal lattice.when we add one ion or metal in another crystal lattice the property of dopped crystal will be different from the element,as because of dopped particles.this is one of the reason.
Compounds are products formed by chemical reaction between elements. A compound is not a mixture but a new substance, having different properties from its constituent elements.
For example, sodium chloride, common salt, is a compound of sodium (a soft silvery metal) and chlorine (a greenish gas). It doesn't look or behave like either of its constituents.
because the alloys are softer and the metals are more reliable. This is because they are higher up in the reactivity series and then they are more reactive.
yesA mixture has chemical properties similar to its constituent elements, because no bonds are formed in the formation of a mixture.However it may have slightly different physical properties. For example, when alloys (mixture of metals) are made, the melting points of some alloys may be reduced.
Alloys are "mixtures" of metals or non-metals in metals. They are developed to create new characteristics of the metals. Carbon (and other things) added to iron makes steel. Precise mixtures makes different sorts of steel alloy. Steel is stronger than iron and can have many characteristics which give superior properties for specific purposes. There is a virtual infinite number of alloys which could be made. Not all will have useful characteristics.
An alloy is a type of metal (specifically, it's a solid solution of dissimilar metals). All alloys are metal, but not all metals are alloys ... pure metals (pure gold or pure copper, for example) are not alloys.
Metals in their pure form have certain properties, but by combining them with other metals, their properties can be vastly improved and tailored for different applications. The resistance to corrosion can be improved by adding a certain amount of one metal, or the strength can be improved by adding another (for example).
Many alloys are made by melting metals and mixing them together in carefully measured amounts.

Melt 2 or more metals together. Also some alloys contain small amounts of nonmetals to produce certain properties (e.g. silicon).
Piston engines are usually Steel, but there are some with major parts of aluminum alloy. Jet engines are made of steel, aluminum and titanium alloys. Each of these type metals have a variety of alloys that have different properties, such as strength, heat resistance and fatigue strength. A design engineer will select the alloy that provides him the properties that he needs for the application.
Silver amalgam for dental fillings is made from mercury and silver. The amalgam used for the reflective properties of a mirror is made from silver and tin.
Many alloys are made by melting metals and mixing them together in carefully measured amounts.
it is made by two or more metals come together.
A house is not usually made from metals.
Gold (and alloys), silver (and alloys), platinum and rarely other metals.
