Nickel belongs to the iron-cobalt group of metals. It forms an adherent oxide film that provides its corrosion resistance up to temperatures around 600°C. It's highly resistant to alkalis and most acids, however, it is attacked by oxidizing acids like nitric and by salt solutions containing oxidizing species. Nickel finds applications in the electronic and aerospace industries and in chemical and food equipment construction. Heat shields, evaporators, laboratory equipment, and glass to metal — ceramic to metal seals are additional applications that use pure nickel.
