Problems solved by technology

However, pure metallic silver has low hardness and ductility, is not easy to manufacture and shape, and is easy to oxidize and change color. It is not suitable for processing jewelry, handicrafts and tableware, so it will be selected in a certain weight component ratio during manufacturing. Add some other ingredients to the silver
[0003] Stirling silver alloy is a silver-copper binary alloy composed of copper alloy elements, in which silver is 92.5wt%, copper is 7.5wt%, which is what we usually call 925 silver, although the silver alloy with copper is added A certain hardness, but the hardness and high temperature resistance are not very significant

Abstract

The invention discloses a high-temperature-resisting silver alloy material. The silver alloy material is prepared through alloy components including, by weight, 80-90 parts of silver, 2-5 parts of copper, 3-5 parts of zinc, 0.2-1 part of cadmium, 0.3-1.2 parts of zirconium, 0.1-0.5 part of indium, 0.2-1 part of beryllium, 0.2-1 part of nickel, 0.3-1.2 parts of magnesium, 0.2-1 part of molybdenum, 0.5-1.5 parts of titanium, 0.3-1.2 parts of cobalt and 0.5-1.5 parts of vanadium. According to the high-temperature-resisting silver alloy material, the stacking fault energy of an alloy matrix is lowered, the diffusion rate of matrix elements is lowered, the effect of strengthening the alloy matrix is achieved, and high temperature resistance of silver alloy is improved; and in the production process, high temperature losses are reduced, and the production cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to a high-temperature-resistant silver alloy material, and also relates to a preparation method of the material. Background technique [0002] Like gold, silver is a kind of precious metal with unique and excellent properties, and is endowed with double value as currency and decoration. However, pure metallic silver has low hardness and ductility, is not easy to manufacture and shape, and is easy to oxidize and change color. It is not suitable for processing jewelry, handicrafts and tableware, so it will be selected in a certain weight component ratio during manufacturing. Some other ingredient materials are added to the silver. [0003] Stirling silver alloy is a silver-copper binary alloy composed of copper alloy elements, in which silver is 92.5wt%, copper is 7.5wt%, which is what we usually call 925 silver, although the silver alloy with copper is added It has a cert...
