1. What is the material purity?Ingots are typically cast from relatively pure materials or precisely controlled alloys
2. What is the economic function?Precious metal ingots serve as currency reserves and investment assets
3. Why do we need ingots for making cars and coins?Ingots are made first so that the metal can be shaped later into parts for cars, coins, and many other things. They help keep the metal pure and ready for more work.
4. How are ingots made from metal?To make an ingot, metal is melted until it is liquid, then poured into a mold. The metal cools slowly so it solidifies in a clean, strong shape.

Metallurgy: The science and technology of metals, including their extraction, purification, and working.
Solidification: The process by which a liquid changes into a solid.
Alloy: A mixture of two or more elements, at least one of which is a metal, to achieve specific properties.
