Abstract

The invention discloses a high-conductivity anti-compression creep aluminum alloy, which comprises the following components in terms of mass percentage: 0.25% to 2.5% of copper, 0.3% to 2.8% of magnesium, 0.03% to 0.5% of rare earth, and 0.3% to 0.3% of iron 1.2%, and the balance is aluminum; also discloses the manufacturing method of high conductivity and anti-compression creep aluminum alloy, including (1) pretreatment of alloy raw materials, (2) alloy batching, melting and furnace treatment, (3) aluminum On-line refining treatment of alloy melt, (4) casting and forming of alloy. The obtained aluminum alloy material not only has high tensile strength and yield limit, but also has excellent electrical conductivity, good thermal stability of resistance at high temperature, and more importantly, the compressive creep resistance of aluminum alloy material at high temperature is also good. It is very excellent, and it is a major breakthrough in the "replacing copper with aluminum" in the electrical industry. It greatly solves the defects caused by the difference in creep performance of aluminum alloy conductor materials in the application process, and meets the performance requirements of aluminum alloy materials in the electrical industry.

Description

technical field [0001] The invention belongs to the field of metal materials, and relates to an aluminum alloy material, in particular to a high-conductivity compressive creep-resistant aluminum alloy and a manufacturing method thereof. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in the industry. Its density is low, but its strength is relatively high, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and Corrosion resistance. At present, in the field of electrical conductors, the use of new aluminum alloy conductors to replace copper conductors and aluminum conductors has become an international development trend. Tensile strength and electrical conductivity have become the main copper products of conductor materials. However, ordinary aluminum alloy conductor materials have ...
