Silicon tombac
Si-l-i-con (say it like "sigh-lee-con") is a special kind of material that's really good at conducting electricity. Think of it like a big pipe that lets electricity flow through it really easily. Scientists figured out that if they mix silicon with other metals like copper and zinc, they can make a new material called tombac.
Now, tombac is stronger than just plain silicon, like how a bike with two wheels is stronger than a unicycle. It's also very shiny and looks like gold, which is why it's sometimes called "false gold."
Scientists found out that they can use tombac to make things like coins, medals, and jewelry because it's so pretty and strong. The best part is that tombac isn't too expensive to make, so lots of people can enjoy things made from it!
