7075 aluminum is a high-strength alloy that belongs to the 7000 series of superhard aluminum alloys.

7075 Aluminum Plate/Sheet is used in aerospace, aircraft, military and automotive applications. 7075 Aluminum is the strongest aluminum, with the strength of many steels while retaining the light weight and corrosion resistance of aluminum. 7075 Aluminum Plate is available in stock in full sizes and custom cut lengths.

7075 is one of the strongest aluminum alloys available, with an excellent strength to weight ratio. 707 Aluminum Plate is ideal for highly stressed aircraft components.

7075 Aluminum Alloy belongs to Al-Zn-Mg-Cu alloy, its composition:

• it is mainly composed of aluminum
• Zinc is the main alloying element, so the corrosion resistance is quite good.
• Adding a little magnesium alloy can make the material reach very high strength after heat treatment.
• Other elements, such as magnesium, copper, and chromium, are also present in smaller amounts.

7075 Aluminum is more embrittled than many other aluminum alloys but has significantly better corrosion resistance than the 2000 series alloys.

The plasticity of 7075 aluminum in the annealed and just quenched state is slightly lower than that of 2A12 in the same state. It is slightly better than 7A04, and the stress corrosion performance of the plate is better than 7A04.

7075 aluminum is not as corrosion-resistant as some other aluminum alloys, especially in humid or salty environments. Therefore, it is often coated or treated to enhance its corrosion resistance.

Combining high strength, lightweight, and excellent machinability, the 7075 aluminum plate is often used in applications requiring high strength and lightweight. Its high strength-to-weight ratio makes it suitable for reducing the weight of overall structures while maintaining structural integrity.

7075 Aluminum Plate Properties

• After solution treatment, the plasticity is good, and the strengthening effect of heat treatment is particularly good.
• It has high strength below 150°C and has particularly good low-temperature strength.
• Welding performance is poor.
• There is a tendency of stress corrosion cracking, and double-stage aging can improve the ability for the alloy to resist stress corrosion cracking.
• It needs to be covered with aluminum or other protective treatment.

Forging 7075 Aluminum

Forging is a common method of forming 7075 aluminum alloy. However, due to the high strength and low ductility of 7075 aluminum, there are some important considerations to keep in mind when forging this alloy:

• Temperature: It is critical to heat the 7075 aluminum to the proper forging temperature. Recommended forging temperatures for 7075 Al is typically in the range of 455-490°C (850-915°F). Heating the material to this temperature range increases its plasticity and reduces the risk of cracking during forging.
• Deformation Rate: Control the deformation rate during forging to avoid excessive strain and the associated risk of cracking. Slow and uniform deformation rates are generally preferred to minimize stress concentrations and maintain material integrity.
• Mold Design: Proper mold design is critical to achieve the desired shape and minimize defects. Molds should have suitable radii and rounded corners to minimize stress concentration points. It is also important to ensure proper lubrication to facilitate the forging process and prevent surface damage.
• Post-forging heat treatment: After forging, 7075 Al can be solution heat treated and then artificially aged to optimize its mechanical properties. This heat treatment process helps improve the strength and performance of forged components.
• Testing and Inspection: Forged components should be thoroughly tested and inspected such as ultrasonic testing, visual inspection, and dimensional inspection to ensure their quality and integrity.

Brazing 7075 Aluminum

Welding 7075 aluminum is challenging due to its high strength and heat sensitivity. However, due to the high strength and low melting point of 7075 aluminum, special considerations are required when brazing this alloy. There are a few key points to keep in mind when brazing 7075 aluminum:

• Choice of Braze Alloy: Choose a braze alloy that is compatible with 7075 aluminum. Common filler alloys for brazing 7075 aluminum include 4043 and 5356. These filler alloys have lower melting points than 7075 Al, allowing them to flow and bond with the base metal during brazing.
• Cleaning and Preparation: Thoroughly clean the surfaces to be brazed to remove any contamination such as oil, grease, or oxides. Surface preparation is critical to ensure good wetting and proper bonding between the filler alloy and the base metal. Mechanical cleaning methods, chemical cleaning methods, or a combination of both can be used.
• Brazing Temperature and Time: Pay close attention to brazing temperature and time to achieve a successful connection. The brazing temperature should be above the melting point of the filler alloy but below that of the base metal (7075 Al). Typically, the brazing temperature range for 7075 Al is approximately 595-650°C (1100-1200°F). The duration of the brazing process depends on the joint configuration and the specific filler alloy used.
• Use of Flux: Apply an appropriate flux to the joint area before brazing to remove oxides and facilitate the flow of the filler alloy. Fluxes designed for aluminum brazing, such as chloride or non-corrosive fluxes, help promote clean and sound joints.
• Joint Design and Clearance: Consider the joint design and provide sufficient clearance for the filling alloy to flow into the joint. Proper clearance is important to ensure capillary action and create a strong brazed joint.
• Post-braze treatment: After brazing, post-braze treatments such as cleaning, inspection, and heat treatment may be required to relieve residual stress and optimize the mechanical properties of the brazed joint.

Milling 7075 Aluminum

Milling is a common machining process used to form and cut 7075 aluminum alloys. Here are some important considerations when milling 7075 aluminum:

• Tool Selection: Choose cutting tools specifically designed for aluminum machining. High-speed steel (HSS) or carbide tools with sharp cutting edges and appropriate coatings such as TiN or TiAlN are typically used for milling 7075 Al. Carbide-cutting tools are generally favored due to their excellent wear resistance.
• Cutting Speed and Feed Rate: Optimize the cutting speed and feed rate for efficient material removal and to prevent excessive tool wear. For aluminum, higher cutting speeds and feeds are generally recommended to achieve better chip evacuation and avoid built-up edge (BUE) formation. Consult the tool manufacturer for recommendations and adjust parameters for your specific milling setup and conditions.
• Coolants and Lubrication: The use of coolants or lubricants during milling helps to dissipate heat, improve surface finish, and extend tool life. Flood coolant or mist coolant systems are often employed to keep the cutting zone cool and lubricate the cutting action.
• Clamping and Rigidity: Ensures that the workpiece is properly clamped and secured to maintain stability and minimize vibration during milling. Rigidity is critical to achieving precise cuts and preventing chatter, especially when machining high-strength materials such as 7075 aluminum.
• Chip control: Pay attention to chip control to prevent chip recutting and tool blockage. Proper chip evacuation is critical to maintaining cutting efficiency and surface finish. Consider using chip breakers, chip evacuation systems, or high-pressure coolant to assist with chip control.
• Surface finish: The choice of milling strategy, such as climb or conventional milling, affects the surface finish of the milled part. Climb milling generally produces a smoother surface finish, while conventional milling may provide better chip control. Experimentation and testing can help determine the best milling strategy for your particular application.
• Workpiece Support: Provide adequate support for the workpiece to minimize vibration and deflection. Properly securing or using a machining center with a rigid structure helps maintain dimensional accuracy and surface finish.
• Tool Inspection and Replacement: Regularly inspect cutting tools for wear and damage and replace them if necessary. Worn or damaged tools can negatively impact cutting performance and lead to poor surface finish or inaccurate dimensions.
