Nickel is an important metal added to 300-series stainless to provide better corrosion resistance, greater strength in high and low temperatures, as well as increased toughness in low temperature. Nickel lowers the effects of work hardening, thus reducing traces of magnetism caused by cold forming and making material flow more freely in manufacturing. These materials are often used in gas turbines and chemical plants because it is capable of withstanding harsh and corrosive environments.
Nickel-titanium alloy, also known as nitinol, is a binary alloy made up of nickel and titanium, these two elements are roughly equal in the atomic percentage (Nitinol 55 and Nitinol 60 are very common). There are two different crystal structures in nickel-titanium alloy due to the change of temperature and mechanical stress, which called austenitic […]
In 1751, Axel Fredrik Cronstedt, working at Stockholm, investigated a new mineral – now called nickeline (NiAs) – which came from a mine at Los, Hälsingland, Sweden. He thought it might contain copper but what he extracted was a new metal which he announced and named nickel in 1754. Many chemists thought it was an […]
