With high melting temperature Tungsten (W), Molybdenum (Mo), which also has high properties such as high melting and boiling point, high thermal resistance, high thermal conductivity and low thermal expansion, Niobium (Nb) which is a ductile and shiny metal, also known as Colombium (Nb), Hafnium (Hf), Vanadium (V), Zirconium (Zr) which can be found in many different compounds, Magnesium (Mg) which is much lighter than aluminum, we call Exotic Metals.
