7075 Aluminum Tube is a high-strength aluminum alloy tube, mainly composed of aluminum, zinc, magnesium and copper, which has excellent mechanical properties and corrosion resistance. Its strength is close to steel but lighter in weight, so it is widely used in aerospace, military equipment, automobiles, motorcycles and other fields with high load requirements.
What is the chemical composition of 7075?
7075 tube is a kind of high strength aluminum alloy with zinc as the main alloying element, its main chemical composition includes: zinc (Zn) content of about 5.1% – 6.1%, magnesium (Mg) content of 2.1% – 2.9%, copper (Cu) content of 1.2% – 2.0%, chromium (Cr) content is usually in the range of 0.18% – 0.28%, silicon (Si) content of no more than 0.4%, iron (Fe) content of no more than 0.5%. 0.4%, iron (Fe) content of no more than 0.5%, the rest is mainly aluminum (Al) and a small number of other impurity elements. These elements work together to give 7075 aluminum alloy its high strength, good toughness, corrosion resistance and other excellent properties.

Description Of 7075 Aluminum Tube
Aluminum 7075 tubes usually have good workability, especially in heat-treated states such as T6 and T651, and show very high strength and hardness, which is suitable for occasions requiring high strength and durability. In addition to this, 7075 aluminum tubes have good welding properties and a low coefficient of thermal expansion. Due to its excellent strength and corrosion resistance, 7075 aluminum tubes are commonly used to make aerospace parts, ship structures, and sports equipment. It should be noted that although 7075 aluminum alloy is strong, it is sensitive to stress corrosion, so when used in specific environments, it requires additional treatment to improve corrosion resistance.

Why does 7075 aluminum alloy have a higher zinc content than other aluminum alloys?
The zinc content of 7075 aluminum alloy is higher than other aluminum alloys, mainly for the formation of MgZn₂ reinforcing phases in the alloy, which can hinder the dislocation movement through its diffuse distribution in the aluminum matrix and significantly enhance the strength and hardness of the alloy to meet the high performance requirements for materials in high-end fields such as aerospace; at the same time, the higher zinc content can expand the solubility of the solid solution in the heat treatment, and more reinforcing phases will be precipitated by aging treatment, further enhancing the performance of the alloy. Further enhance the performance of the alloy. In addition, zinc’s own corrosion resistance can be synergized with other elements to form a dense oxide film on the alloy surface and improve corrosion resistance, and zinc can also be combined with magnesium, copper and other elements to achieve a good balance of strength, toughness, corrosion resistance and other properties, in order to adapt to the diversified needs of different application scenarios.
What are the mechanical properties of 7075?
7075 aluminum alloy has excellent mechanical properties, its tensile strength is usually ≥560MPa, such as 7075 – T651 state up to 572MPa, yield strength ≥495MPa, 7075 – T651 yield strength of 503MPa, showing a strong resistance to tensile and deformation; elongation is generally ≥6%, 7075 – T651 can reach 11%.
