Because they may fuse, block or displace other metals! :)

Why metals are used as an alloy?
Pure metals often do not have properties optimal for real world applications. Alloying can get you closer.
What is the purpose of alloying steel?
Creating an alloy out of any metal is for garnering the properties of both types of metals. Sometimes for anti-corrosive properties or strenghtening, or even causing a metal to be more maleable while not breaking.
Why is an aluminium alloy stronger?
Added alloying (Cu, Mg, Mn, Zn, Si, Zr etc.) metals have the special role to improve mechanical properties of aluminium.
What two properties of gold can be altered by alloying?
gold
What are three advantages of some alloys when compared to pure metals?
Alloys are sometimes more useful than pure metals because alloys are stronger - or tougher (toughness is resistance to fracture). Pure metals tend to be softer than alloys and therefore tend to get dented, scratched, or broken/fractured more easily. Alloys are often lower cost than pure metals but not necessarily so. As an example, stainless steel is more expensive than pure iron.
Why are alloys perferable at times?
Alloying of metals is used to improve the mechanical properties, resistance to corrosion, stabilization of the crystalline structure, increasing the hardness, resistance to high temperatures etc.
What is the difference between doping and alloying?
A doping essentially done for change in the properties of materials without change in their crystal structure. In an alloy the structure and properties of the developed alloy may be very different from the parent materials.
Why is alloying necessary?
Because it improves the material properties of the resulting metal.
How the melting temperature properties generally change as you go down the columns of the periodic table?
The melting temperature properties generally change as you go down the columns of the Periodic Table by decreasing for metals and increasing for non-metals.
What has properties of metals and non metals?
The metalloids have properties of both metals and nonmetals.
What chemcial processes can make metals look like gold?
Alloying metals allows obtaining several alloys similar to gold.
What do you call metals that contain other elements mixed with them?
A metal that contains other elements to give it specific properties is called an Alloy. Many metals can contain other elements to give the metal specific properties. Steel is an alloy of Iron and carbon. Stainless steels contain various other alloying elements such as Chromium and Nickel.
