Pure nickel, a metal with an extremely high melting point, is unique in the metal world with its melting point as high as 1455°C. Its outstanding performance is not only reflected in its excellent mechanical properties and hot and cold pressure processing properties, but also in its excellent corrosion resistance.

Pure nickel's corrosion resistance is so strong that it performs well in a variety of environmental conditions. It can be hailed as one of the best materials resistant to corrosion by hot and concentrated alkali solutions. Whether it is the atmosphere, fresh water or sea water, pure nickel can maintain good chemical stability. At the same time, it can also resist corrosion from neutral and slightly acidic solutions and organic solvents, further proving its excellent corrosion resistance.

However, while pure nickel has so many advantages, it also has some limitations. Pure nickel cannot resist corrosion from oxidizing acids and high-temperature sulfur-containing gases, which limits its application range to a certain extent. Therefore, when choosing to use pure nickel, it is necessary to fully consider its use environment and conditions.

Despite these limitations, pure nickel still finds widespread use in a variety of fields. In mechanical and chemical equipment, pure nickel is often used as corrosion-resistant construction and structural parts of precision instruments. In the electronics and radio fields, pure nickel is also used to make vacuum tubes and radio equipment parts. In addition, pure nickel also plays an important role in the medical and food industries, such as in the manufacture of tableware and utensils.

Pure nickel has won widespread praise for its unique properties and wide range of applications. In the future, with the advancement of science and technology and people's continuous pursuit of material properties, the application fields of pure nickel will be further expanded.
