iron-nickel
Planetary center composition
Iron-nickel describes an alloy composed primarily of iron and nickel, found naturally in meteorites and the Earth's core.
The term appears most often in geology and astronomy: an iron-nickel meteorite, the iron-nickel composition of the inner core.
The alloy's durability and magnetic properties make it significant in both scientific study and industrial applications.
