0 Materials with the Highest Melting Point in the World

4. Tungsten (3400 ℃). Tungsten takes the 4th spot in our list of the materials with the highest melting point.. Tungsten is a steel-gray or silver-white metal with high hardness, high melting point, and resistance to air erosion at room temperature. As a refractory metal (generally, the melting point is higher than 1650℃) with the highest melting point, it has good high-temperature strength.

High Temperature resistance materials

This material is recently discovered in the list of refractory materials. One of the reasons of alloying this material with others is that it helps to produce ductility and tensile strength. One of the main properties of rhenium is that it acts as a alyst in many chemical reactions. So the above-described metals are the main refractory/ high-temperature resistant metals. Other metals do not
