Why is nichrome wire used in heater?

Nichrome wire is used as a heating element because it is very stable, even at high temperatures.

Unlike other metals, it will not melt even when generating large amounts of heat. Ironically, nichrome actually has low electrical resistance, the property that causes the wire to heat.
