A kind of aluminum alloy rod and its preparation method and the preparation method of aluminum alloy wire

Abstract

The invention relates to an aluminum alloy rod and a preparing method thereof as well as a preparing method of an aluminum alloy wire. The aluminum alloy rod comprises the following components in a percent by weight: 0.1-2.5% of Fe and 0.1-0.8% of Mg and further comprises 0.005-2.0wt% of one or a mixture of more than two of Cu, Zr, Ni, Mn, Re, Ti and B and the balance of aluminum and impurities. For the aluminum alloy rod provided by the invention, the constitution, ratio and adding sequence of intermediate alloy are screened through a large quantity of experiences, the contents of all components are controlled by adopting a method which adds intermediate alloy and pure metal according to the sequence, and the aluminum alloy rod meeting requirements can be obtained. Besides, through in-furnace and online degassing devices, the hydrogen content of molten aluminum alloy is reduced to a value smaller than or equal to 0.18ml / 100g; and through carrying out online grain refining on Al-Ti-B wires, the ductility of the aluminum alloy rod is improved.

Description

Technical field: [0001] The invention relates to an aluminum alloy rod, a preparation method thereof, and a preparation method of an aluminum alloy wire. Background technique: [0002] Existing plugs and sockets for household and similar purposes are generally made of copper conductors. In China, where copper resources are extremely scarce, "using aluminum to save copper" is no different from an industrial revolution. With the development of conductor alloys The development of globalization and the introduction of aluminum alloy wire will drive the rapid development of the entire aluminum alloy wire industry for household appliances. However, when the aluminum alloy wires made of existing aluminum alloy rods are used for making household and similar plug sockets, the creep resistance is poor, they are not resistant to high temperatures, and they do not have good bending performance and impact resistance. The rate and tensile strength are also not up to the requirements requ...

Problems solved by technology

However, the aluminum alloy wire made of existing aluminum alloy rods has poor creep resistance, high temperature resistance, and good bending performance and impact resistance when making household and similar plug and socket wires. The rate and tensile strength are also not up to the requirements of wires for plugs and sockets for household and similar purposes.
