Refractory metals are a class of metals that are extraordinarily resistant to heat and wear. Refractory metals are said to be poorly resistant to oxidation and corrosion.
The definition which elements belong to this group differes. The wider definition includes 10 elements of the Group 4, Group 5 Group 6 excluding the transuranium element but including the Group 7 element rhenium, while some definitions include the five metals tungsten, molybdenum, niobium, tantalum and rhenium.
The high melting point makes them useful in many applications.
Household incandescent bulbs contain refractory metals in their tungsten filaments, and nearly all manufactured goods, particularly those containing metal or electronics, contain or were produced using refractory metals.
