Mercury is classed as a rocky body like the Earth. Its core (about 1800 kilometers in radius) is likely almost all iron. The mantle (about 600 kilometers thick) contains mostly silicates, as does the relatively thin crust.
Overall, the best estimates are that 70% of the planet's mass is iron and the other 30% is silicate material.
