Among aluminum alloy materials, 7075 aerospace aluminum sheet is undoubtedly a representative of "high-end strength." As an aluminum-zinc-magnesium-copper series ultra-hard aluminum alloy, it boasts strength approaching that of low-alloy steel, excellent fatigue performance, and dimensional stability, making it a core material in aerospace, high-end manufacturing, and other fields.
1. T6 Temper: 7075-T6 aluminum plate is the most common high-strength temper, produced through a "solution treatment + artificial aging" process. Tensile strength reaches 500-570 MPa, and yield strength 430-500 MPa, reaching peak strength. It is suitable for applications requiring extremely high strength and with less demanding corrosive environments, such as molds and sporting goods.
2. T651 Temper: Based on the T6 temper, stress relief treatment is added, effectively preventing deformation and warping after processing. It offers even greater dimensional stability and is commonly used for large structural components and precision machined parts. It is one of the commonly used tempers in the aerospace field.
3. T73 Temperament: Optimized corrosion resistance through "over-aging" treatment, its stress corrosion cracking life is more than 10 times that of the T6 temper, while maintaining high strength (tensile strength approximately 540 MPa). Suitable for applications requiring long-term exposure to humid and complex environments, such as aircraft wings and marine equipment components.
In addition, the O temper (annealed state) also has limited applications, primarily for scenarios requiring subsequent cold forming, but its strength is significantly lower than that of the heat-treated state.
1. Thin Plates: Thickness 1.0-4mm, common widths 1000mm, 1250mm, 1500mm, and lengths 2000mm, 2440mm, 3000mm. Suitable for precision parts and small molds.
2. Medium-Thick Plates: Thickness 5-15mm, width 1000-2000mm, and lengths 2000mm, 2500mm, 3000mm. Commonly used in aircraft structural components, automotive chassis parts, and other medium-load-bearing components.
3. Thick Plates: Thickness 20-40mm and above, width and length can be customized, with a maximum width of 2300mm and a length customizable up to 8000mm. Primarily used for heavy-duty applications such as large molds, armor plates, and aircraft landing gear.
In addition, commonly available plate sizes include 1500×3000mm, 1520×3020mm, and 2000×6000mm, directly matching most standardized processing needs.
1. Aerospace: This is the core application of 7075 aluminum plates, commonly used in critical load-bearing components such as aircraft wing frames, landing gear parts, fuselage bulkheads, and missile structural components. For example, the wing spars and longitudinal beams of well-known aircraft models such as Boeing and Airbus rely on its high strength and fatigue resistance, achieving weight reduction of over 30% compared to traditional steel, significantly improving flight efficiency.
2. Military Equipment Sector: Due to its high hardness and strong impact resistance, it is widely used in armor protection plates, firearm parts, and military vehicle frames, meeting the stringent requirements of military products for protection and load-bearing capacity.
3. High-End Manufacturing Sector: This includes mold manufacturing (small and medium-sized plastic molds, die-casting molds), medical devices (surgical robot arms), and transportation (high-speed train frames, precision parts for automobile chassis). In mold manufacturing, 7075 aluminum plates can improve processing efficiency by more than 25% and significantly reduce mold weight.
4. Sports Equipment Sector: High-end trekking poles, bicycle frames, golf club heads, and other products also use 7075 aluminum plates, ensuring sufficient strength while making the equipment lighter and improving the user experience.
