7075 aluminum tube its strength and hardness are higher, but in the use of the situation may appear cracking, then how do we avoid 7075 aluminum tube cracking?Next 7075 aluminum tube manufacturers will give you an introduction.

7075 aluminum tube solid solution treatment temperature 460℃~490℃, aluminum plate treatment temperature should be close to the lower limit, the number of repeated treatment should not be more than 2 times, to avoid alloy elements through the cladding diffusion, reduce the corrosion resistance of the material.The heating temperature of extruded material is 460℃~471℃.After incubation or hot water quenching or other suitable cooling medium at room temperature, the transition time shall be < material I mechanics, many materials require high hardness, and the amount of deformation (simply is reduced brittleness) is common application of poor steel and ordinary steel used in buildings, such as buildings, in bridge construction.Using poor quality steel products, excess weight occurs, without deformation of 7075 aluminum tubes, it will be destroyed and collapse.Mainly because of the impurities contained in the steel, similarly, 7075 aluminum pipe cracking analysis of the main reason is aluminum.

Suggestions to avoid 7075 aluminum tube cracking:

1. Reduce the content of inclusions and improve the degree of materials.

2. Improved the design, element heating and aging annealing process, and reduced the content of delta ferrite in aluminum matrix materials.

3. Increase the deformation radius so that the material can uniformly deform and avoid excessive concentration of stress.

4. When the finished material is not under stress, deformation and aging is one of the main processing methods for the mechanical manufacturing industry to provide the blank of mechanical parts.By forging, not only the shape of the mechanical parts can be obtained, but also the internal metal structure can be improved to improve the mechanical and physical properties of the metal.Turbine generator shafts, rotors, impellers, blades, rope rings, large hydraulic press columns, high pressure cylinders, rolling mill rolls, internal combustion engine crankshafts, connecting rods, gears, bearings, and other important components of the defense industry and guns are forged products.Therefore, forging production is widely used in metallurgy, mining, automobile, tractor, harvesting machinery, petroleum, chemical, aviation, aerospace and other industries.
