Final answer:
Alloys are substances made by combining solid solutions of metals, creating materials with enhanced properties, such as brass, bronze, and steel.
Step-by-step explanation:
The solution that makes a new type of metal by combining solid solutions of other metals is known as an alloy. An alloy is a substance made by melting two or more elements together, at least one of them metal. Some common examples of alloys include brass, bronze, and steel.
These materials are very useful in various applications due to their enhanced properties compared to the individual metals they are composed of. For instance, bronze, which is mainly composed of copper with added tin, was used historically for making weapons due to its hardness and toughness.
