Problems solved by technology

For example, ZTJ series profiles require 6063 alloy to have a conductivity of 32.5MS / m on the basis of meeting the national standard strength, HLP series profiles require 6101B alloy performance to meet the national standard, and the resistivity is lower than 0.0320Ω.mm² / m. Existing ordinary aluminum alloy profiles The conductivity can only reach 30.2MS / m, so there is an urgent need for an aluminum alloy profile with high mechanical strength and high conductivity

Embodiment 1

[0024] Embodiment 1: A high-conductivity high-strength aluminum alloy conductive profile, its composition and mass percentage are: Mg is 0.57%, Si is 0.41%, Fe is 0.10%, Cu is 0.02%, Mn is 0.08%, Cr 0.08% for Ti, 0.02% for Ti, 0.03% for Zn, 0.05% for the rest of the impurities alone, 0.15% for the sum of the rest of the impurities, and the balance for Al. The Fe, Zn, Ti alloy composition is smaller than the content of the 6063 alloy national standard, which not only improves the purity of the 6063 alloy, but also improves the electrical conductivity; adding Cu element, and controlling the Cu content of the 6063 alloy national standard below the limit, A small amount of Cu is combined with the main strengthening components Si and Mg to significantly improve the mechanical properties, which can make the mechanical properties close to the properties of duralumin, and Cu can neutralize the adverse effect of Ti on the electrical conductivity; due to the uncontrollable Fe element in ...

Description

technical field [0001] The invention relates to the field of aluminum alloy materials, in particular to a high-conductivity and high-strength aluminum alloy conductive profile and a production process. Background technique [0002] Since the 21st century, the construction of urban rail transit with the characteristics of energy saving, high speed and large capacity has attracted more and more attention from many cities. Urban rail transit is an urban public passenger transport system that uses dedicated rail-guided operation, including subway systems, light rail systems, trams, monorail systems, automatic guided rail systems, urban express rail systems and maglev systems. Because smooth, efficient and reliable traffic travel is not only the basis for travelers to choose travel methods, but also the goal pursued by urban traffic managers. Therefore, urban rail transit has become an important part of urban public transportation due to its characteristics of fast, convenient, ...
