Silver ornament alloy taking silver as main component

Abstract

The invention relates to a silver ornament alloy, particularly relates to the silver ornament alloy taking silver as a main component, and belongs to the technical field of non-ferrous metal. The silver ornament alloy taking silver as the main component is prepared by taking the following components by weight part: 93-95 parts of silver, 2-4 parts of copper, 1-3 parts of titanium and 1-3 parts of chromium, wherein the purities of all the components are 99.9%-99.99%. The silver ornament alloy is prepared according to the following steps of: weighting the raw materials by weight part of all components; placing the components into a vacuum furnace in turn; melting in a vacuum electric arc furnace with the vacuum degree at 0-5Pa and the temperature at 1860-1890 DEG C; keeping the temperature for 1 hour, and then uniformly stirring; pouring and placing into a mould; and cooling at a speed of 30-45 min. A detection result shows that the silver ornament alloy taking silver as the main component has the advantages that the silver ornament alloy is brighter (whiter) than the s925 international sterling silver, the silver ornament alloy is characterized by anti-oxidation and corrosion resistance and is harder, the hardness is 4.5-5.2, and the silver ornament alloy is more durable and attractive and has a better health-care function for the human body.

Description

technical field [0001] The invention relates to a silver jewelry alloy, in particular to a silver jewelry alloy mainly composed of silver, which belongs to the technical field of non-ferrous metals. Background technique [0002] The existing international standard for standard silver jewelry alloys is 92.5% silver and 7.5% copper. This silver alloy has higher hardness than 99.9% pure silver, and is resistant to oxidation and corrosion, but its color is dark and the surface is easily oxidized and discolored. It is not very hard, and the utensils and ornaments made of it are easily scratched and damaged, and the jewels inlaid on the ornaments are not very firm. Oxidation and discoloration of silver jewelry will greatly affect its appearance, and the jewelry made is not durable, which will affect its safe use. Contents of the invention [0003] The object of the present invention is to provide a silver, copper, titanium and chrome jewelry alloy with silver as the main compon...
