7075 aluminum tubing is predominantly used in aircraft, characterized by its low density and lightweight, with hardness up to 1.5-2 times higher than regular aluminum alloy tubing. However, it's also more expensive than standard aluminum tubing of the same size, thus determining its use mainly in aviation and expensive, precision equipment.

Aluminum tubes refer to pipes made of pure aluminum or aluminum alloys. They are categorized by shape as square tubes, round tubes, and extruded profiles. By thickness, they are divided into thick-walled aluminum tubes and thin-walled aluminum tubes. In terms of precision, there are ordinary aluminum tubes and precision aluminum tubes, with precision tubes typically requiring further processing after extrusion, such as cold-drawn and precision-extracted aluminum tubes. Production methods include drawing, rolling, and extrusion, with drawing tubes commonly used for medium and low-pressure pipelines. Aluminum tubes are a type of non-ferrous metal tube, which is a metal tube material formed by pressing and drawing, featuring a hollow structure along its entire length. They may have one or more sealed through-holes, with uniform wall thickness and cross-section, and are usually delivered in straight lengths or coils.

Performance: Corrosion-resistant, lightweight.

Aluminum tubes are widely used across various industries, including automotive, marine, aerospace, aviation, electrical, agriculture, electromechanical, and household sectors. Aluminum tubes are now an indispensable part of our lives.

Common aluminum tube grades: 1060, 6063, 6061, LY12 (2024/2A12), 3A21, 3003, 6005, 7075, 5A02, 5A06, 5052, 5056, 5083. Among them, 7075 is a cold-processed forging alloy with high strength, far exceeding soft steel.

7075 is one of the commercial high-strength alloys. It boasts standard corrosion resistance, excellent mechanical properties, and anodic reaction. The fine grain structure enhances deep hole drilling capabilities, improves tool wear resistance, and makes threading more distinctive.

Processing characteristics of 7075 aluminum tube:

7075 aluminum is known as ultra-high-strength aluminum alloy, with its yield strength nearly equal to its tensile strength, high yield ratio, and high specific strength. However, it has lower plasticity and high-temperature strength, making it suitable for load-bearing structural components used at room temperature and below 120°C. The alloy is easy to machine and boasts good corrosion resistance and high toughness. It is widely used in the aerospace industry and has become one of the key structural materials in this field.
