Expert Answer:

Alloys are usually stronger than pure metals as many pure metals are weak. Alloys often combine properties of different metals together e.g. resistance to corrosion (copper) and strength (iron). 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.
