Alloys

The video explores the evolution and significance of alloys, starting with the creation of bronze, a mixture of tin and copper, which marked the beginning of the Bronze Age. It explains how alloys, being mixtures of metals with different atomic sizes, have unique properties that make them harder than pure metals. The video also discusses modern alloys like steel, duralumin, and mercury amalgam, highlighting their applications. Finally, it covers gold alloys, explaining how mixing gold with other metals affects its strength and value.
