An alloy is a solution of metals and/or combined with one or more non-metals. It is a solution because one metal (solid) dissolves in another metal (solid) and may contain other elements (solid) as well. An alloy retains the properties common to metal, but is not pure metal.
Examples:Brass (copper and zinc)
Steel (iron and carbon)
Bronze (copper and tin)
They are a physical change because it is not like burning where a new substance is being formed.
Metal alloys are used whenever a pure material does not have the desired characteristics. For example, pure gold is beautiful, but relatively soft and does not keep its shape well. A gold alloy is just as pretty, but is hard enough to resist dents. Iron is hard, but rusts quickly. Steel, an alloy of iron, carbon and other metals, is harder and more durable.
Alloys can add heat resistance to a metal
They are easy to shape into new things They are unlikely to break and very solid
neither it is chemical
We use aluminium to make alloys. Alumina is a example.
copper
Alloys are metal mixtures. For example, Sterling silver is a mixture of silver and copper.
mixing paints and mixing alloys
Usually because alloys are stronger or otherwise have better properties in one way or another.
For example all steels.
The plural form of the noun alloy is alloys.The plural possessive form is alloys'.Example: We've tested all of these alloys' strength.
it means to ore the iron into an object example car alloys
For example vodka is a homogeneous mixture of water and alcohol.
Two of the earliest alloys were bronze (copper with tin) and brass (copper with zinc).
Example of superconducting alloys: Nb-Ti, Nb-Sn, V-Ga.
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.
