High entropy alloys

High entropy alloys are special kinds of materials that are made from combining different metals that have different ingredients. They are really strong and also really resistant to changes in temperature so they can be used in lots of different things. These alloys have a high entropy which means they are made up of lots of different metals and have a lot of diversity in the makeup of the material. This makes them very strong and reliable.
