Jewelry 10K black gold with excellent abrasion resisting performance and technology of jewelry 10K black gold

Abstract

The invention discloses jewelry 10K black gold with excellent abrasion resisting performance and a technology of the jewelry 10K black gold. An alloy comprises components including, by weight percent,0.5 wt.% -0.8 wt.% of Sr, 2.0 wt.%-3.5 wt.% of Zn, 1.0 wt.%-1.5 wt.% of Ca, 1.4 wt.%-1.8 wt.% of Nb, 18.0 wt.%-20.0 wt.% of Sn, 10.0 wt.%-15.0 wt.% of Fe, 40.0 wt.%-42.0 wt.% of Au and the balance cobalt. The jewelry 10K black gold with the excellent abrasion resisting performance and the technology of the jewelry 10K black gold avoid the current situation that current K black gold performance isinsufficient, and the development bottleneck in the jewelry field is effectively broken through. It can be predicted that rice economic gains and social benefits can be obtained through material implementation and industrialization.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a gold alloy. Background technique [0002] One of the characteristics of gold is its softness, so it is difficult to inlay various exquisite styles, especially when inlaid with pearls, gemstones and emeralds, it is easy to be lost. Generally speaking, pure gold is relatively speaking. K gold is an alloy smelted together with gold and other metals. The English word for alloy, Kara Gold, is referred to as K gold for short. If pure gold is divided into 24 parts, then 1 part is 1K, and the gold content per K is calculated to be 4.15%. Due to the addition of other metals, the different K numbers of K gold jewelry are formed. Therefore, in our country The common purity standards of gold jewelry mainly include 24K, 22K, 18K and 14K. 24K is for pure gold, which means that the gold content is above 99.6%. [0003] With the addition of different elements and content, K gold can show dif...

AI Technical Summary

Problems solved by technology

Not only is it not easy to process, but also has limited commercial applications, and the market sales are not large

In addition, the black color of jewelry made of this material will fade after 1 year of use

In addition, due to the influence of aging, the strength and hardness of the material will continue to increase during use, causing the material to become brittle and brittle to fracture

It not only affects the look and feel of this type of material, but also seriously reduces the market sales and marketing of this type of material

[0007] Although my country's jewelry and decoration industry has relatively large absolute figures in terms of quantity and output, the scale of enterprises is small and the core competitiveness is not strong.
