It depends on the specific metal or alloy you are referring to.
Alloys are harder than the components.
John Martin Harder has written: 'Thermodynamic properties of liquid metals and 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.
Alloys (mixtures of metals and other elements) have different properties form pure metals.Two examples:An alloy of carbon & iron males steel which can be much harder than ironAn alloy of copper and tin makes bronze which is harder and more corrosion resistant than either of the pure metals

Alloying metals make them stronger because in pure metals all the atoms are the same size and ordered but when another element is added then it makes the atoms irregular making the layers harder to shift, making it stronger.An alloy is a mixture of two elements, one of which is a metal. Alloys often have properties that are different to the metals they contain. This makes them more useful than the pure metals alone. For example, alloys are often harder than the metal they contain.Alloys contain atoms of different sizes, which distorts the regular arrangements of atoms. This makes it more difficult for the layers to slide over each other, so alloys are harder than the pure metal.
Alloys contain metals but also nonmetals.
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.
Alloys are typically harder than pure metals because the addition of different elements in an alloy disrupts the regular arrangement of atoms in the crystal lattice structure, making it more difficult for the atoms to slide past each other. This disruption increases the strength and hardness of the material, making it more resistant to deformation or damage.
Alloys are several metals, and possibly some other substances, mixed together.
