Abstract

The invention relates to the technical field of alloy materials, in particular to an environment-friendly high-corrosion-resistance copper-aluminum rare earth alloy material for electric power and a preparation method thereof. The composition comprises the following components in percentage, by weight, 3.0 wt% to 4.5 wt% of Cu, 0.05 wt% to 0.15 wt% of Ti, 0.01 wt% to 0.3 wt% of Mn, 0.01 wt% to 0.3wt% of Cr, 0.02 wt% to 2 wt% of rare earth Re and the balance of Al. the copper is added to improve the casting surface quality and form a copper-aluminum compound with aluminum, so that the strengthof the alloy is improved, and the corrosion resistance of the copper element is improved, under the synergistic effect of the aluminum element and the aluminum element, when the surface is oxidized,the conductivity can not be reduced; the titanium can be added to refine grains, the casting surface quality is improved, the titanium and aluminum form an aluminum-titanium compound, and the strengthof the alloy is improved; meanwhile, due to the synergistic effect of the titanium element, the electric conductivity is not reduced; the rare earth element is added, so that the metal crystal structure in the alloy can be better optimized, the toughness of the alloy is improved, the bending cracks are greatly improved, the overall conductivity of the product is improved, and meanwhile, the physical and mechanical properties of the alloy are greatly improved.

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to an environment-friendly and highly corrosion-resistant copper-aluminum rare-earth alloy material for electric power and a preparation method thereof. Background technique [0002] Many fields of electrical materials use copper, aluminum or steel as part of electrical equipment. However, copper is expensive to use as a conductive material, and copper has low strength and poor friction resistance. Aluminum is easily oxidized and non-conductive when used as a conductive material. Galvanized As an electrical material, steel is cheap, but has poor corrosion resistance in harsh environments, and cannot meet the requirements of some special equipment. In view of this, we provide an environment-friendly and highly corrosion-resistant copper-aluminum rare-earth alloy material for electric power and a preparation method thereof. Contents of the invention [0003] The purpose of ...
