There are different melting points at different parts of the earth.
It's because of the massive pressure in the inner core part.
The inner core is the innermost layer of the earth. It is dense and solid, and is 1,200km thick. It is made of iron and nickel and is a solid ball of metal. It's also the hottest layer of all. It has the most pressure than all the other layers.
The pressures from surrounding material is so intense that despite the high temperatures, the metals of the inner core cannot melt.
The inner core is under enormous pressure, which raises the temperature needed to melt it above its actual temperature.
