Aluminium magnesium boride

Aluminium magnesium boride (AlMgB14) is a type of metal made from aluminium, magnesium, and boron. It's not found in nature, so it has to be made in a laboratory. The metal is very strong and light, and it's usually used in things like airplanes and rockets, because it doesn't break easily and is also good at conducting electricity. It's also good at handling high temperatures.
