Copper Nickel Alloy, also known as CuNi alloy, combines the best properties of both copper and nickel. It is non-magnetic, light in weight and a good conductor of electricity. It also has high corrosion resistance and is machinable. The alloy is used for a variety of applications, including marine engineering and automotive engineering. It is also often found in electrical components, such as wires and cables, precision and vitreous resistors, and potentiometers.
The aim of the current article was to synthesize copper-nickel alloy nanospheres with spherical shape, high purity and tunable and well-controlled size. The resultant products were characterized by SEM, TEM, high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) and STEM-EDS elemental mapping images as well as by X-ray diffraction pattern. The results showed that the diameter of the product can be controlled from 6.9 to 27.3 nm by simply changing the volume of TOP. Moreover, the elemental ratio of Cu to Ni in the resultant product was kept almost the same as that in the precursors (Fig. S2-S5 and Table S1+).
The Cu-Ni alloy can be used in various industries, such as marine engineering, automobile, aerospace and electrical engineering. It is a popular material due to its high corrosion resistance and machinability. The alloy also has antimicrobial properties, which makes it a great choice for hospitals and other health care facilities. It is commonly used for engine blocks and suspension systems in cars, as well as marine propellers and hulls. In addition, it can be used for cryogenic applications and is found in brake tubing.
