This super hot iron cannot melt because of all the pressure.
Assuming you're talking about the Earth's core. It' solid due to the immense pressure.
The iron core of the earth is solid because the immense pressure near the center of the earth, due to gravity, keeps the iron in a solid state, even though it is hot.
Earth's core is a solid made up of mainly iron and other metals. Even though temperatures here reach sometimes 5000-7000 degree Celsius but pressure is extremely high. Due to this high pressure, the metals remain solid even though temperatures exceed their melting points.
solid due to extreme pressure, even though it is composed of mostly iron and nickel.
The inner core is made out of iron and nickel and it is a solid.
It is because the outer core is not under enough pressure to be solid, so it is liquid even though it has a composition similar to that of the inner core.

Because it contains magma
you tested
The inner core is solid, even though it has a high temperature, because of the high pressure in the center of Earth.

have a nice day!
The pressure (due to gravity) in the center of the Earth is so great, that it compresses the otherwise molten metal alloy - to a solid.
The immense pressure inside Earth keeps the inner core solid even though it is well above its normal melting temperature.
The inner core of the Earth is solid due to high pressure pushing in on it from all directions, which prevents it from melting even though it is extremely hot. The heat generated by the decay of radioactive elements also helps maintain the inner core's solid state.
