7075 Aluminum Alloy Sheet Product Details

の 7075 aluminum alloy sheet stands out in numerous fields with its excellent performance and has become an indispensable and important material in modern industrial manufacturing.

I. Product Characteristics

High Strength: 7075 aluminum alloy belongs to the Al-Zn-Mg-Cu super duralumin series and is one of the most powerful commercial alloys. After heat treatment, it can exhibit extremely high strength. Its tensile strength can reach 524 メガパスカル, and the 0.2% yield strength reaches 455 メガパスカル, far exceeding that of mild steel, providing a solid guarantee for applications with various high-strength requirements.

Good Mechanical Properties: It has outstanding comprehensive mechanical properties. 例えば, it has good ductility, with an elongation rate of up to 11%, enabling it to adapt to complex processing techniques to a certain extent without easily breaking. At the same time, it has a relatively high elastic modulus of 71 Gpa, ensuring the stability and rigidity of the material under stress.

Excellent Machinability: The material is easy to process. The fine grains make the deep drilling performance more outstanding. During the machining process, the wear resistance of tools is enhanced, and thread rolling is smoother and more efficient, greatly improving production efficiency and product quality.

Corrosion and Oxidation Resistance: It has ordinary corrosion resistance and can effectively resist the erosion of corrosive media in general environments. さらに, it has good oxidation resistance. A dense oxide film can form in the air to protect the internal metal from further oxidation, extending the service life of the product.

Significant Heat Treatment Strengthening Effect: Through appropriate heat treatment processes, its strength, hardness, and other properties can be significantly improved to meet the diverse requirements of different engineering scenarios for material properties.

II. 化学組成
