Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are ferromagnetic at or near room temperature; the others are iron, cobalt and gadolinium.Its Curie temperature is 355 C (671 F), meaning that bulk nickel is non-magnetic above this temperature.
