Among aluminum alloys, 7075 aluminum plate is a representative material in the high-strength category. As a high-strength aluminum alloy, it stands out from other aluminum materials with its high hardness, excellent tensile strength, good processability, and corrosion resistance, making it a common material in many high-tech fields and industrial applications.
The aerospace industry places extremely stringent demands on materials, demanding both structural strength under extreme conditions and the need to reduce weight to reduce energy consumption. With a tensile strength exceeding 570 MPa and a density of only 2.81 g/cm³, EN AW 7075 fully meets this core requirement and is a key material in the aerospace industry.
In aircraft manufacturing, 7075 aluminum sheet has a wide range of applications. For example, in aircraft wing spars, fuselage frames, and landing gear components, these structures must withstand enormous loads and impacts. The high strength of 7075 aluminum sheet effectively ensures flight safety. Furthermore, compared to traditional steel, its lightweight properties significantly reduce fuselage weight and improve aircraft fuel efficiency. 7075 aluminum sheet is also commonly used in lightweight structural components for satellites and spacecraft. The material's stable mechanical properties and corrosion resistance ensure long-term, reliable operation in the complex radiation and temperature fluctuations of space.
As the automotive industry shifts toward lightweighting and new energy vehicles, demands for material strength and weight reduction continue to rise. The use of 7075 aluminum sheet in the automotive manufacturing sector is gradually increasing, particularly in high-performance sports cars and new energy vehicles.
For high-performance sports cars, 7075 aluminum sheet is primarily used for chassis components, suspension systems, and body frames. For example, control arms and steering knuckles in sports cars require structural stability during high-speed driving and intense maneuvers. The high hardness and fatigue resistance of 7075 aluminum sheet effectively enhance vehicle handling and safety. Furthermore, its lightweight properties reduce vehicle inertia, optimizing acceleration and braking performance.
In new energy vehicles, 7075 aluminum sheet is primarily used for battery housings and structural supports. New energy vehicle battery packs account for a significant portion of vehicle weight. Using 7075 aluminum sheet to manufacture the battery casing not only reduces vehicle energy consumption and extends range through lightweighting, but also protects the battery through its corrosion resistance, mitigating safety risks caused by environmental factors.
In industrial mold and machinery manufacturing, material durability and processing precision directly impact product quality and production efficiency, and the performance characteristics of 7075 aluminum sheet are fully utilized in this area.
In mold manufacturing, 7075 aluminum sheet is commonly used to make templates and mold bases for plastic and stamping molds. Its high hardness (reaching 150-170 HB after T6 heat treatment) allows it to withstand the wear and tear of repeated mold opening and closing and stamping processes, extending mold life. Furthermore, 7075 aluminum sheet exhibits excellent machinability, making it easy to machine high-precision mold cavities and structures, ensuring the dimensional accuracy of the finished product.
In machinery, 7075 aluminum sheet is used to manufacture high-precision mechanical components, such as guide rails for CNC machine tools and support brackets for drive shafts. These components must maintain stability even at high speeds. The vibration resistance and dimensional stability of 7075 aluminum sheet effectively reduce mechanical errors and improve processing precision and reliability.
Beyond the aforementioned core applications, 7075 aluminum sheet, due to its excellent overall performance, is also widely used in sports equipment and electronic devices.
In sports equipment, 7075 aluminum sheet is used in high-end bicycle frames, ski bindings, trekking poles, and other products. For example, the lightweight design of 7075 aluminum sheet reduces riding strain, while its high strength allows it to withstand the impact of complex road conditions, meeting the needs of professional cyclists. Ski bindings require structural stability in low-temperature environments, and the low-temperature resistance of 7075 aluminum sheet ensures proper operation in icy and snowy conditions.
In the electronic equipment sector, 7075 aluminum sheet is used in laptop cases and high-end camera frames. This type of product has high requirements for appearance texture and heat dissipation performance. After anodizing treatment, the 7075 aluminum plate can present a delicate surface effect and at the same time has good heat dissipation to ensure the stability of electronic equipment during long-term operation.
