Abstract

The invention discloses a high-performance composite metal product for weak-current contacts. The high-performance composite metal product comprises a first metal layer which is a surface layer and a second metal layer which is an inner layer. The first metal layer is composed of, by weight, 55-62 parts of gold, 14-18 parts of rhodium, 5-8 parts of iridium, 7-11 parts of tantalum, 3-6 parts of cobalt and 2-5 parts of yttrium. The second metal layer is composed of, by weight, 60-68 parts of gold, 17-21 parts of rhodium, 8-12 parts of platinum, 4-7 parts of nickel, 6-9 parts of copper and 3-6 parts of hafnium. By adoption of a composite structure, the high-performance composite metal product has advantages of high hardness, high oxidation resistance, high corrosion resistance and long service life.

Description

A kind of weak current contact high performance composite metal product

Technical field

The present invention relates to a kind of weak current contact high performance composite metal product.

Background technology

Steel Wire Products Industry includes structured metal product manufacture, metal tools manufacture, container and packaging container of metal Manufacture, rustless steel and similar daily metallic article manufacture etc..With the progress and the development of science and technology of society, metallic article is in work The utilization of the various fields of recent life of industry, agricultural and people is more and more extensive, also to the value that social creativity is increasing.It is existing Various metallic articles used in technology often only produce single absolute construction when being produced, but often also deposit when using In many problems, often Performance comparision is single when such as homogenous material is used, it is impossible to reach the expected using effect of enterprise instantly, Cannot promote the use of on a large scale.

The content of the invention

It is an object of the invention to provide one kind is arranged using composite construction, with hardness height, good in oxidation resistance, corrosion-resistant Property is good, long service life the characteristics of weak current contact high performance composite metal product.

The technical scheme is that, a kind of weak current contact high performance composite metal product, including the first of top layer The second metal layer of metal level and internal layer, the first metal layer is made up of gold, rhodium, iridium, tantalum, cobalt and yttrium, shared by each composition Parts by weight are respectively：The gold accounts for 55-62 parts, and the rhodium accounts for 14-18 parts, and the iridium accounts for 5-8 parts, and the tantalum accounts for 7-11 parts, The cobalt accounts for 3-6 parts, and the yttrium accounts for 2-5 parts, and the second metal layer is made up of gold, rhodium, platinum, nickel, copper and hafnium, each composition institute Account for parts by weight to be respectively：The gold accounts for 60-68 parts, and the rhodium accounts for 17-21 parts, and the platinum accounts for 8-12 parts, and the nickel accounts for 4-7 Part, the copper accounts for 6-9 parts, and the hafnium accounts for 3-6 parts.

In a preferred embodiment of the present invention, parts by weight shared by each composition of the first metal layer are specially：It is described Gold accounts for 56 parts, and the rhodium accounts for 15 parts, and the iridium accounts for 6 parts, and the tantalum accounts for 8 parts, and the cobalt accounts for 4 parts, and the yttrium accounts for 3 parts, and described Parts by weight shared by each composition of two metal levels are specially：The gold accounts for 61 parts, and the rhodium accounts for 18 parts, and the platinum accounts for 9 parts, the nickel 5 parts are accounted for, the copper accounts for 7 parts, and the hafnium accounts for 4 parts.

In a preferred embodiment of the present invention, parts by weight shared by each composition of the first metal layer are specially：It is described Gold accounts for 61 parts, and the rhodium accounts for 17 parts, and the iridium accounts for 7 parts, and the tantalum accounts for 10 parts, and the cobalt accounts for 5 parts, and the yttrium accounts for 4 parts, and described Parts by weight shared by each composition of two metal levels are specially：The gold accounts for 67 parts, and the rhodium accounts for 20 parts, and the platinum accounts for 11 parts, described Nickel accounts for 6 parts, and the copper accounts for 8 parts, and the hafnium accounts for 5 parts.

It is of the present invention for a kind of weak current contact high performance composite metal product, the present invention is set using composite construction Put, the characteristics of with hardness height, good in oxidation resistance, good corrosion resistance, long service life.
