Chromium-copper alloy and preparation method thereof

Abstract

The invention relates to a chromium-copper alloy, which is characterized by comprising 0.5 to 2.0% of chromium, 0.01 to 1.0% of tellurium, and the balance being copper and other impurities. The provided chromium-copper alloy can be made into high-precision high-yield contact tubes and electrode caps, is a low-price, high-precision, and high-yield anticorrosive material, and has an extremely high hardness at a high temperature, and moreover, the wear resistant performance between the alloy and contact surfaces (welding wires, etc.) is greatly improved.

Description

technical field [0001] The invention relates to the application field of alloy steel, in particular to a chrome-copper alloy and a preparation method thereof. Background technique [0002] With the continuous update and development of aerospace vehicles, the requirements for material performance are getting higher and higher. The working conditions of aerospace vehicles are very complicated, and most components are in service under high composite stress, high temperature and environmental erosion. The main requirements are high temperature resistance, low temperature resistance, high specific strength, high specific stiffness, fatigue resistance, corrosion resistance, long life and low cost. In the current elastic alloy market, the elastic material used in high-end products is cobalt-based 3J21 alloy. Although many well-known manufacturers have done a lot of work to improve and stabilize the performance of elastic materials such as 3J21 alloy, they have not essentially solve...
