Oxygen-free copper

Okay kiddo, have you ever seen a penny that is really shiny and new? Well, that penny is made out of copper which is a metal that comes from the ground.

When copper is taken out of the ground, it usually has some oxygen in it. Oxygen is something we breathe in the air and it can change the way copper looks and behaves. That's why some pennies look brown and dirty instead of shiny.

Oxygen-free copper is a special kind of copper where almost all of the oxygen has been taken out. This means it looks and behaves differently than regular copper. It's really shiny and has a smoother texture.

This type of copper is important in making things like wires, because it conducts electricity really well. That means it can move electricity from one place to another without any interruptions or delays.

So, just like we need to take our vitamins and eat healthy foods, copper needs to have the oxygen taken out of it to be the best version of itself.
