7075 Produktdetails von Aluminiumlegierungblättern

Der 7075 Aluminium -Leichtmetallblech zeichnet sich in zahlreichen Bereichen mit seiner hervorragenden Leistung aus und ist zu einem unverzichtbaren und wichtigen Material in der modernen industriellen Herstellung geworden.

ICH. Produkteigenschaften

Hohe Stärke: 7075 Aluminiumlegierung gehört zur Serie Al-Zn-Mg-Cu Super Duralumin und ist eine der mächtigsten kommerziellen Legierungen. Nach Wärmebehandlung, Es kann extrem hohe Stärke aufweisen. Seine Zugfestigkeit kann erreichen 524 Mpa, und die 0.2% Ertragsfestigkeit erreicht 455 Mpa, weit über den von Weichstahl hinaus, Bereitstellung einer soliden Garantie für Anwendungen mit verschiedenen hochfesten Anforderungen.

Gute mechanische Eigenschaften: Es hat hervorragende umfassende mechanische Eigenschaften. Zum Beispiel, Es hat eine gute Duktilität, mit einer Verlängerungsrate von bis zu 11%, enabling it to adapt to complex processing techniques to a certain extent without easily breaking. Gleichzeitig, 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. Darüber hinaus, 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. Chemische Zusammensetzung
