Abstract

The invention discloses a corrosion-resistant rare earth copper alloy, and belongs to the field of copper alloys. The corrosion-resistant rare earth copper alloy is prepared from the following components in percent by mass: 70-75% of Cu, 2.0-4.0% of Al, 3.0-3.5% of Ni, 0.2-1.8% of Si, 0.002-0.060% of Zr, 0.5-0.8% of Re, 1.6-2.0% of Cr, 0.5-1.5% of Fe, 2.5-3.0% of Mn and the balance of Zn and inevitable impurities. The content of the impurities S is controlled to be smaller than or equal to 0.02%, and the content of the impurities P is controlled to be smaller than or equal to 0.02%. The prepared corrosion-resistant rare earth copper alloy is excellent in heat conduction performance, high in strength, good in corrosion resistance and excellent in physical performance. Meanwhile, the copperalloy is easy to machine, can be widely applied to the fields of machining, hard alloys and the like, and has good practical application value. Test results show that compared with common copper alloys, the tensile strength of the corrosion-resistant rare earth copper alloy is improved by 35% or above, and the corrosion resistance is improved by 50% or above.

Description

technical field [0001] The invention relates to the field of materials, especially the field of rare earth alloys, in particular to a corrosion-resistant rare earth copper alloy. Background technique [0002] As a commonly used non-ferrous metal, copper has a wide range of applications and plays an important role in social and economic development. It has been widely used in many fields such as machinery, chemical industry, military affairs, and construction. Pure copper is purplish red, also known as red copper, which has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. [0003] The copper alloy is an alloy composed of pure copper as the base and adding one or several other elements. Copper alloy has the advantages of strong chemical stability, easy welding, high thermal conductivity and electrical conductivity, high tensile strength, excellent plasticity and ductility, etc. Based on the excellent performance of copper alloy, it...
