In precision industries such as aerospace and high-end equipment manufacturing, 7075 T7351 aluminum plate, with its superior mechanical properties and stable processing characteristics, has become a core choice for high-end aluminum alloy materials. As a company deeply involved in aluminum plate manufacturing for many years, we understand the stringent requirements of precision industries for materials. From alloy composition control to heat treatment process optimization, every step directly affects the final application effect of the product.

Precisely adapting the specification system is the foundation for the application of 7075 T7351 aluminum plate. 7075 aluminum belongs to the Al-Zn-Mg-Cu series of ultra-high-strength aluminum alloys, conforming to international standards such as ASTM B209 and EN 485. Common thicknesses range from 6-200mm, widths from 1000-2600mm, and lengths from 2000-12000mm. Special sizes can also be customized according to requirements, it is worth noting that for export products, we exercise extra strict control over dimensional tolerances and surface roughness, ensuring that the flatness error of the 7075 aluminum plate is ≤0.5mm/m and the surface finish reaches Ra≤0.8μm, adapting to the equipment installation precision requirements of different countries and regions. In terms of composition, its precise ratio of zinc content (4.0-4.9%) and magnesium content (2.1-2.9%) provides a core guarantee for subsequent heat treatment strengthening.

The special heat treatment process of the T7351 temper gives the 7075 aluminum plate irreplaceable core advantages. Compared to ordinary aluminum alloys, its yield strength can reach over 434MPa, and its tensile strength ≥503MPa, while also possessing excellent resistance to stress corrosion cracking—this is the key difference between the T7351 temper and other heat treatment tempers. In production practice, we have found that by optimizing the solution treatment temperature (470-480℃) and aging process, the toughness and fatigue strength of the material can be further improved, ensuring an elongation rate of over 10%, balancing high strength and machinability. Furthermore, 7075 t7351 aluminum plate possesses excellent machinability and weldability. After surface treatments such as anodizing and spraying, its corrosion resistance meets the requirements of harsh working conditions such as marine environments and high temperatures, which is a key reason for its widespread export to Southeast Asia, Europe, and other regions with diverse climates.

Based on the above characteristics, the application scenarios of 7075 T7351 aluminum plates are highly focused on high-end precision fields.
In the aerospace field, it can be used for key structural components such as aircraft wing spars and landing gear parts; its lightweight and high-strength characteristics can effectively reduce fuselage weight and improve endurance.
In high-end equipment manufacturing, it is suitable for core components such as precision molds and CNC machine tool guideways; its stable mechanical properties ensure long-term operational accuracy.
In the marine engineering field, after special anti-corrosion treatment, it can be used for ship decks and offshore platform supports to resist salt spray corrosion.
Drawing on our export experience, we offer customized solutions for various application scenarios. For example, we provide ultrasonic flaw detection services for aerospace customers and optimize sheet flatness for mold customers, effectively addressing their practical application pain points.

Years of manufacturing and export experience have taught us that the value of 7075 T7351 aluminum plate lies not only in the material's inherent performance but also in their precise adaptation to specific application scenarios. Moving forward, we will continue to deepen our research and development of alloy material technologies and optimize production processes to provide global customers with more professional and personalized high-performance aluminum plate products, contributing to the high-quality development of high-end manufacturing.
