Optimization of the composition of jewelry alloy white gold

The article shows the possibility of optimizing the composition of the alloy of white gold due to the introduction of the modifier components. The choice of modifying components was carried out taking into account their impact on the security and the reliability index of a jewelry alloy. Proposed alloy compositions of white gold with the content of modifying components. Justified the introduction in the composition of alloys of gold-based system Au-Ag-Cu in certain quantities Zn, Se, Sb, In, Cr, Kd or Ga to produce alloys of white color.
