Abstract
The invention provides chromium-copper alloy steel. The alloy steel is characterized by comprising the following components in percentage by weight: 0.5 to 2.0 percent of chromium, 0.01 to 1.0 percent of tellurium, and the balance of copper and impurities. The chromium-copper alloy steel can be used for manufacturing contact tubes and electrode caps with high accuracy and high yield. The anticorrosive material with low price, high accuracy and high yield is high in hardness particularly at a high temperature, so that the abrasive resistance of the chromium-copper alloy steel in contact with welding wires and other surfaces can be greatly improved.
Description
Technical field
The present invention relates to the Application Areas of steel alloy, especially about a kind of chrome copper and preparation method thereof
.
Background technology
Continuous renewal and development along with aerospace flight vehicle, also more and more higher to material performance requirement, the working conditions of aerospace flight vehicle is very complicated, most of member is on active service under high compound stress, high temperature and environmental attack, so be high temperature resistant, low temperature resistant, high specific strength, high specific stiffness, antifatigue, corrosion-resistant, long lifetime and low cost to the major requirement of aerospace material.On current elastic alloy market, the resilient material that high-end product is used is cobalt-based 3J21 alloy, although a lot of well-known manufacturers improve and stable resilient material as the performance of 3J21 alloy done a lot of work not from solve in essence this alloy qualitatively, use the problem existed.
Summary of the invention
In order to solve an above-mentioned difficult problem, the object of the present invention is to provide chrome copper of a kind of high-temp and high-strength and preparation method thereof, suitably added the chromium that China has resources advantage in known formulations, improved technique simultaneously, reduce S(sulphur) P(phosphorus) content, reached the property indices of similar products at home and abroad fully.
Technical scheme of the present invention is achieved in the following ways: a kind of chrome copper steel by weight percentage, is characterized in that: it contains promising 0.5～2.0% chromium, 0.01～1.0 tellurium, and all the other are copper and impurity.
A kind of method for preparing the chrome copper steel comprises the following steps: in temperature, be to carry out the solutionizing processing under 940～980 ℃ and temperature is to carry out ageing treatment under 430～470 ℃; Obtain existing very high hardness, electric conductivity, and there is good machinability.
The present invention, can produce ignition tip, the electrode cap of high precision, high yield.The impregnating material of its low price, high precision, high yield, particularly at high temperature, have very high hardness, greatly improved the wear resistance with contact surfaces such as welding wires.
Embodiment
