A kind of silver alloy material with high hardness and high temperature resistance and preparation method thereof

Abstract

The invention provides a high-hardness and high-temperature-resistant silver alloy material. The high-hardness and high-temperature-resistant silver alloy material is characterized by comprising the following alloy ingredients in parts by weight: 90-95.0 parts of silver, 1.4-3.0 parts of copper, 2.2-3.5 parts of zinc, 0.2-0.8 part of nickel, 0.5-1.2 parts of ferrum, 0.6-1.0 part of titanium, 0.3-0.6 part of cobalt, 0.7-1.0 part of tungsten, 0.2-0.5 part of molybdenum and 0.5-1.2 parts of vanadium. The high-temperature resistance of the silver alloy is improved through the added alloy ingredients, the problems that a silver alloy produced by adopting a conventional silver alloy production technology is low in hardness and does not resist high-temperature are solved, the production cost is greatly lowered, and the development prospect is great.

Description

technical field

[0001] The invention relates to the field of chemical materials, in particular to a silver alloy material with high hardness and high temperature resistance and a preparation method thereof. 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 certain hardne...
