Nickel bar has good mechanical strength and ductility, refractory, air - free oxidation characteristics. Nickel is a silvery white metal. The melting point is 1726K, the boiling point is 3005K, and the density is 8.902g/cm3.

Nickel rods exhibit good corrosion resistance in many acidic and alkaline environments and are often used in reducing media.

Nickel bar has magnetic and good plasticity, good corrosion resistance, no oxidation in the air, and strong alkali resistance. It can be dissolved slowly in dilute acid, releasing hydrogen gas to produce green nickel ion Ni2+. The oxidant solution, including nitric acid, did not react. Nickel is a medium strength reducing agent. Nickel has also been successfully used in dry chlorine and hydrogen chloride at room temperature to 540℃. It can also be used in stationary hydrofluoric acid solutions. Nickel has good mechanical properties in a relatively wide temperature range and is easy to cold work.
