Abstract

The invention provides an aluminum alloy material, a preparation method of the aluminum alloy material and application. The aluminum alloy material comprises, by mass, 0.25-0.35% of iron, 0.1-0.25% of copper, 0.2-0.4% of magnesium, 0.05-0.15% of zinc, 0.1-0.3% of silicon, 0.01-0.05% of boron, 0.2-0.35% of scandium, 0.05-0.15% of ruthenium and the balance aluminum. The aluminum alloy material is obtained through the method that aluminum ingots are molten, added with other components of the formula ratio, and then sequentially subjected to melting, pouring, homogenizing treatment, water quenching and aging treatment. Aluminum alloy prepared through the preparation method serves as a guide line material, and has high tension strength, elongation and specific conductance at the same time.

Description

technical field [0001] The invention belongs to the technical field of alloy materials, and in particular relates to an aluminum alloy material, its preparation method and application. Background technique [0002] my country has a huge demand for wires and cables. With the rapid increase in copper prices and the increasing scarcity of resources, the research and development and industrialization of aluminum conductors have attracted much attention. Compared with copper, aluminum is cheaper and lighter in weight. Under the same mass, the ampacity of aluminum is much higher than that of copper. Therefore, aluminum is the most promising metallic material to replace copper on transmission lines. [0003] However, aluminum has insufficient strength and toughness, is easily broken, and its electrical conductivity is only 61% IACS (International Annealed Copper Standard). By adding trace amounts of other elements to aluminum to form aluminum alloy materials, it can have a strong...
