The Friedel spherical period oscillation (FSPO) phenomenon caused by electron density scattering from impurity atoms is investigated in this work using high-elasticity copper alloy as an example. First, in accordance with the theory behind this phenomenon, the range of the smallest electrical neutrality scale that stabilizes in the based alloy is established when impurities are present. Next, this range is contrasted with the face-centered cubic (FCC) solid solution’s lattice point locations. The adsorption atomic radius is considered to determine the truncation radius of FSPO and to further determine the shielding range of the electron wave of impurity atoms. In this study, we determine the chemical formula of neighboring and secondary neighboring atoms in the FCC solid solution alloy using the Cowley parameters of two neighboring shells of the alloy, which were obtained using X-ray and neutron diffraction equipment. With A, B, and C standing for the various atom types in the alloy and the number of secondary adjacent atoms x = 2 or 3, the formula can be broadly written as [AB12]Cx. The analytical approach described in this work can also be applied to examine other multicomponent high-elasticity alloys, including those found in the Monel series. The results of this study show that various industrial grades of highly elastic alloys can have their chemical formulas determined more easily by theoretically analyzing the relationship between alloy composition and properties from the viewpoint of the nearest-neighbor local electronic structure. This method provides a solid theoretical direction for both the creation of new alloys and the enhancement of performance in already existing alloys. In addition, the analytical framework introduced in this work can be further applied to the innovative design of high-elasticity alloys exhibiting enhanced physical characteristics, thus assisting sensor technology researchers in refining manufacturing processes and facilitating the creation of sensors with improved functionality.
