Material formula of 18K gold bullet and gold bracelet and preparation process of 18K gold bullet and gold bracelet

Abstract

The invention discloses a material formula of a 18K gold bullet and gold bracelet and a preparation process of the 18K gold bullet and gold bracelet. The material formula of the 18K gold bullet and gold bracelet includes the following components in parts by weight: 75.2% of gold, 0.00496% of silver, 13.69208% of copper, 7.44248% of nickel, and 3.66048% of zinc, or 75.2% of gold, 0.00992% of silver, 7.27384% of copper, 12.66536% of nickel, and 4.85088% of zinc. The preparation process of the 18K gold bullet and gold bracelet comprises the steps of cutting, heating die and polishing. By means of the invention, the bracelet has high hardness,certain elasticity, flexibility, extensibility and a wider space for designing styles, can be bent, and is convenient to wear.

Description

technical field [0001] The invention relates to a precious metal formula and a preparation process for the precious metal, in particular to a formula for an 18K gold elastic gold bracelet and a preparation process for the 18K gold elastic gold bracelet. Background technique [0002] With the development of the market economy and the improvement of people's living standards, since the mid-1990s, the pattern of traditional gold jewelry dominating the world has been broken by the quietly emerging platinum and colored precious metal jewelry, and the trend is increasing year by year. [0003] Usually, white and colored precious metal materials in jewelry include white 18K gold, colored 18K gold, platinum, etc. The traditional process is to add a small amount of other metal elements to the main precious metal element and complete it by alloying. However, in recent years, due to the continuous improvement of product quality and craftsmanship, the requirements for materials are als...

Problems solved by technology

[0004] Precious metal composite materials are composite materials based on precious metals and their alloys, and meet the characteristics of metal matrix composite materials, such as high wear resistance and good fluidity. At present, as far as precious metal composite materials are concerned, the main difficulties are: : (1) Harmful chemical reactions such as serious interface reactions and oxidation reactions will occur during high temperature manufacturing

(2) The wettability between the precious metal matrix and the reinforcement is poor, even non-wettable

Therefore, the produced precious metal jewelry has only hardness, not enough elasticity, and the design lacks room for development. Therefore, it is necessary to produce a kind of jewelry with high hardness, which is slightly higher than 18K gold, and has a certain degree of elasticity, bendability, and K gold elastic material bracelet formula of stretchability and ductility and preparation technology of K gold elastic material bracelet
