The process of mixing two or more metals to create a new material with enhanced properties is referred to as alloying. This involves combining different metals in specific proportions to achieve desired characteristics such as increased strength, improved corrosion resistance, or enhanced ductility.

Alloys often exhibit superior physical and chemical properties compared to the individual metals used to create them. For example, steel is an alloy made primarily of iron mixed with carbon, which significantly improves its strength and durability compared to pure iron.

In contrast, tempering and annealing refer to heat treatment processes aimed at altering the mechanical properties of a metal, not mixing metals. Blending generally refers to combining materials but does not exclusively pertain to metals, thus distinguishing alloying as the correct term for the process of mixing metals.
