Tungsten
Generally, tungsten.
Advantages are that Tungsten is a very good electricl conductor. Better than copper
Tungsten in the form of Tungsten carbide is widely used in masonry drill tips, and in paint scrapers for handymen. It has a significant use in the filament of incandescent light bulbs. As a weld application, it may be used as a hardening on the cutting edge of the blades of bulldozers, and excavator buckets. So very few countries would not use tungsten.
Because tungsten is having high resistance and therefore heat loss will be more
tungsten has high resistivity and resistance but at a higher temperature it becomes hot and oxidised and melted so we can't use tungsten as heating coil
