Abstract

The invention discloses a corrosion-resistant and wear-resistant high-conductivity alloy for sockets. The alloy comprises the following components in percentage by weight: 21-23% of zinc, 2-3% of aluminum, 0.2-0.4% of phosphorous, 1.5-2.5% of silver, 0.1-0.5% of yttrium, 1.5-2.5% of chromium, 0.3-0.5% of nickel, 1-2% of vanadium, 0.1-0.3% of lead and the balance of copper. The invention also provides a preparation method of the corrosion-resistant and wear-resistant high-conductivity alloy for sockets. The preparation method comprises the steps such as smelting, draw casting, hot rolling, solid solution, finish rolling and aging treatment. The corrosion-resistant and wear-resistant high-conductivity alloy for sockets disclosed by the invention has relatively high conductivity and hardness, good corrosion resistance and good properties in elasticity, strength and the like, basically reaches or exceeds the properties of common tin-phosphorous bronze materials, can completely meet the material requirements of socket sleeves and is a very proper substitute material; due to low dosage of precious materials, the cost is greatly reduced; and meanwhile, the preparation method is simple in process and easy to implement and thus is suitable for industrial mass production.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to a corrosion-resistant and wear-resistant high-conductivity alloy for sockets. Background technique [0002] The socket is one of the most widely used power connectors, in which the material of the socket in the socket plays an important role. In my country, the vast majority of socket materials are made of tin phosphor bronze, which has excellent properties such as high strength, elasticity, wear resistance and electrical conductivity, but the price of tin phosphor bronze is relatively expensive. Costs are under enormous pressure. [0003] Therefore, it is an urgent problem to develop an alloy material that can replace the tin phosphor bronze material, especially an alloy material for socket sleeves with corrosion resistance, wear resistance and high electrical conductivity. Contents of the invention [0004] The technical problem to be solved by the present invention is to prov...
