With the development of global manufacturing technology, new technologies, new materials, new processes, and new products for the protection of power equipment and facilities are emerging in an endless stream. The protection of wires and cables for remote transmission of high-voltage power makes power equipment use high-strength and high-conductivity aluminum The demand for alloy thick-walled pipe conductors is increasing. When high-strength and high-conductivity aluminum alloy thick-walled pipes are used in the protection of power facilities, they must have high strength, good plasticity, high specific strength, light weight, high conductivity, and high Toxicity, good corrosion resistance, no stress corrosion cracking, strong resistance to intergranular corrosion, good welding performance, unchanged corrosion resistance of the welding zone, good machinability, etc., and has good process performance, suitable for cutting and bending processing , It is suitable for various forms of surface oxidation and corrosion protection treatment, and maintains good performance in atmospheric acid-base, high cold, high heat, transformation, repair, wind and sand and other environments.
Considering that the main strengthening elements of 6101B aluminum alloy are few, the alloy is simple, so the strength is not high, but in the high temperature heating process, the transformation temperature of the main strengthening elements increases, and the solid solubility increases significantly. The alloy has obvious quenching aging strengthening effect. The range is wide, allowing online quenching, and the amount of Cu in the alloy is small. Therefore, a small amount of zinc is added to improve the strengthening effect of the alloy and increase the strength of the 6101B alloy. The mechanical properties and electrical conductivity of the
6101B T7 aluminum bus tubes used for power equipment are stable.
6101B T7 aluminum bus tubes is online quenched and meets the requirements of high strength and high conductivity, tensile strength 210-245MPa, yield strength 155-189MPa, elongation 15-19%, Brinell hardness 70-79HB, electrical conductivity 55.8-56.1% IACS ; National standard requirements: tensile strength 2 170 MPa, yield strength 2 120 MPa, 12% of elongation, Brinell hardness of 2 56 HB, conductivity of 2 55.17% IACS.
