This article gives deep insights into the research of changing properties' consistency of the alloys on the basis of gold in the system Au-Ag-Cu (gold, silver-copper) which are represented on the ground of mathematical models in order to enhance efficiency of the alloys' composition suitable for the jewelry production.
The main aim of the research is the development of the scientific-methodological principles of the patterns' estimation of the mass content's influence of the main alloy components (copper and silver) on the formation of the attributes of the golden alloy using the simplex of the lattice method.
The simple equation has been obtained, which gives the possibility to calculate the chemical composition and indices of alloys' properties (solidus temperature, liquidus, hardness, mechanical durability) on the basis of gold in order to design the jewelry with the stated consumption properties.
The influence of the alloy's components in the system Au-Ag-Cu aimed at the change of the properties' change has been established, precisely the temperature solidus, liquidus, hardness, durability of the jewelry.
