Problems solved by technology

At present, there is no copper-based alloy in the market, and the appearance has a rose color
In addition, because real rose gold is prone to discoloration during use, scratches on the surface, and brittle fracture during use and manufacturing, which seriously hinders the market share of this product
[0008] However, it must be noted that although my country's jewelry industry, especially gold alloys for jewelry, has developed rapidly, due to its late start and low starting point, there is still a big gap compared with the international level in some technical links.
The long-term unsolved problems in the industry not only affect the market sales and user experience of related products, but also seriously limit the market share of such products in the international field
The development and industrialization of rose-colored copper alloys has become an inevitable problem in the field of jewelry. For a long time, many domestic research institutions and enterprises have made multi-faceted attempts, but unfortunately, no substantial results have been achieved so far. progress

Abstract

The invention discloses a rose copper alloy with brittlement resistance, wear resistance, low cost and rose color. The alloy comprises the following components in percentage by weight: 1.2-1.4 wt.% ofIn, 0.4-0.6 wt.% of Ca, 1.8-2.5 wt.% of Ti, 0.2-0.3 wt.% of C, 2.0-3.5 wt.% of Mg, 0.6-0.8 wt.% of Ru, 4.0-5.0 wt.% of Pd, 60.0-65.0 wt.% of Cu, and the balance of silver. The invention provides therose copper alloy not existing on the market yet; and the alloy is excellent in wear resistance. When the types of copper alloys for jewelries are greatly enriched through advanced material design, the cheap rose material is provided to the market.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a copper alloy. Background technique [0002] Gold is a soft, golden-yellow and corrosion-resistant precious metal. Gold is very stable and hardly reacts with anything to produce compounds. It is soft and easy to process, and it has a dazzling and golden color that is rare in nature. It has long won the fascination and admiration of human beings, and it has naturally become a symbol of wealth. [0003] Colored gold is actually a general term for colored gold, that is, a general term for gold alloys of various colors formed by adding alloying elements to gold. Except for white gold, others are called prize money, and the most common one in our life is 18K prize money. K is an international symbol used to represent the purity of gold. The reason for the color is that the types and proportions of metals are different. When gold is added to copper, aluminum, silver, cobalt, pallad...
