It depends of the use the element is intended for. Example: Iron is a pure metal, however many times steel is prefeared because is stronger and has a higher melting point. Steel however is not an alloy, its a carbide(metal+carbon), but i can't think of anything else right now.
Alloys are useful improvement over pure metals because they tend to be stronger.
Alloys have useful properties that are not found in the pure metals from which they are mixed. You can make alloys that are stronger, lighter, more corrosion resistant, and so forth, as compared to pure metals at a comparable price range.
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.
Copper alloys are more useful than pure copper because they have enhanced properties such as increased strength, hardness, and corrosion resistance. By combining copper with other metals, alloys can be tailored to suit specific applications, making them more versatile and suitable for a wider range of uses than pure copper.
Alloys are sometimes more useful than pure metals because alloys tend to be stronger though not necessarily. Pure metals tend to be softer than alloys, which are a mix of two or more metals, and therefore get dented, scratched, or broken more easily. Gold used in jewelry is a good example. Metal alloys have different structural and behavioral characteristics than pure metals. Alloying a metal also gives it a different appearance. In some cases alloys may result in a lighter metal without sacrificing other necessary characteristics. They may also be more cost effective.

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.
Alloys are not necessarily harder or stronger than pure metals. For example gallium and aluminum form an alloy that is extremely weak. Many of the alloys we know of are stronger than pure metals because those are the ones we find most useful. In most pure metals, there will be gaps in between atoms. In many alloys we fill in those gaps with some other type of atom, adding extra support.
Copper alloys are more useful than pure copper because they often have enhanced properties such as increased strength, improved corrosion resistance, and better electrical conductivity. By combining copper with other metals, these alloys can be tailored to meet specific application requirements, making them more versatile and valuable in various industries.
Metals are usually more useful when mixed because alloying can improve their mechanical properties, such as strength, hardness, and corrosion resistance. By combining different metals, it is possible to create alloys with a wide range of properties tailored to specific applications. Additionally, alloys often have better performance characteristics compared to pure metals.
A pure metal contains only one metal while an alloy is a mixture of two or more metals.
There are a few different reasons. 1. Some alloys are stronger than natural metals. 2. Weight, if you need a light weight material, alloys have more to offer, eg. aluminum. 3. Cost 4. Flexibility These are just a few of the many answers.
