Alloying is the process of combining two or more metals to create a new material with enhanced properties. This technique is commonly used to improve strength, durability, and resistance to corrosion. For example, adding carbon to iron produces steel, which is much stronger than pure iron. Different alloys can be tailored for specific applications by adjusting the composition of the metals involved. For instance, adding nickel and chromium to steel creates stainless steel, known for its resistance to rust and staining. Alloying plays a crucial role in various industries, including construction, automotive, and aerospace.
