Analysis of Nickel's Properties and Applications
Nickel (Ni) is a relatively refractory metal. Despite its high strength, it exhibits significant volatility and a large coefficient of linear expansion, coupled with low thermal conductivity. These properties constrain nickel's performance at elevated temperatures, particularly under high thermal loads where its strength diminishes markedly. Consequently, nickel is typically limited to operating temperatures not exceeding 1000–1100°C.
Due to nickel's low thermal conductivity, power generated by its anode surface cannot be effectively dissipated unless the surface undergoes special treatment to enhance radiation capacity. Consequently, this aspect requires particular attention in applications demanding high-efficiency heat dissipation. Furthermore, nickel's high linear expansion coefficient contributes to the deformation of its components under high thermal loads.
Nevertheless, nickel's strength and ductility after annealing often surpass those of many other metals. At room temperature, nickel also exhibits excellent machinability, enabling the production of dimensionally precise, complex-shaped products through various mechanical pressure processes such as forging, stamping, pressing, rolling, and wire drawing. Consequently, nickel is widely used in manufacturing precision components, particularly in environments requiring high-temperature resistance and corrosion resistance.
