7050 aluminum angle is a high-strength, heat-treatable aluminum alloy profile primarily used in aerospace and other structural applications that demand exceptional strength, corrosion resistance, and toughness. Made from 7050 aluminum alloy—well known for its outstanding mechanical properties and excellent resistance to stress corrosion cracking—it is ideally suited for load-bearing framework structures.
Compared to general-purpose aluminum alloys, 7050 aluminum angle offers a higher strength-to-weight ratio, making it particularly suitable for high-performance structures operating in harsh environments. In critical applications, 7050 is often used as an upgraded alternative to 7075 aluminum due to its superior corrosion resistance and improved toughness in thick sections. Quick Quote

Common types of 7075 aluminum angle
7050 equal aluminum angle
The equal 7050 aluminum angle is the most common standard profile, featuring two sides of equal length and a standard 90-degree angle. It is suitable for most symmetrical connections and structural reinforcement applications. With balanced load-bearing and easy installation, it is widely used in aerospace structural frames, brackets, and reinforcement components.
7050 unequal aluminum angle
The unequal 7050 aluminum angle is ideal for space-constrained or specialized connection structures. One leg is longer than the other, offering a larger support surface or greater installation flexibility. It is commonly used in irregular frame connections and structural reinforcement where customized structural adaptation is required.
7050 inside radius aluminum angle
This type of aluminum angle features a rounded inside corner instead of a sharp angle, which helps reduce stress concentration and improve fatigue resistance. It is especially suitable for structural components with high fatigue life requirements, such as those used in aerospace, rail transit, and precision equipment.
7050 outside radius aluminum angle
The outside radius aluminum angle features rounded outer corners, offering a more refined and visually appealing appearance. It is often used in visible components or structures that require enhanced edge safety. Typical applications include equipment enclosures, frame protection, and display structures.
7050 heavy-duty aluminum angle
This type of aluminum angle is designed for heavy-load structures, featuring thicker walls, higher strength, and enhanced stability. It is suitable for high-strength applications such as aerospace ground equipment, military armor frames, and construction machinery structures.
7050 custom aluminum angle
Custom aluminum angles made from 7050 alloy can be tailored according to customer drawings or specific requirements, including non-standard angles (such as 45°, 60°, 135°, etc.), leg lengths, and wall thicknesses. They are ideal for specialized industrial equipment, structural engineering, and precision assembly components.
The above are the common types of 7050 aluminum angles offered by Chalco, covering a wide range of standard structural forms to meet the high-strength application needs of aerospace, defense, machinery, transportation, and more.

Features of 7050 aluminum angle
Excellent stress corrosion resistance
Compared to 7075, 7050 demonstrates significantly better resistance to stress corrosion cracking, especially in thick sections. This makes it ideal for structural components exposed to moisture, corrosive environments, or long-term loading, offering extended service life.
Superior toughness and fatigue resistance
While maintaining high strength, 7050 also provides excellent toughness and fatigue resistance. It performs reliably in environments with frequent vibrations or alternating loads, making it widely used in aerospace connectors and load-bearing supports under dynamic conditions.
Optimized for thick sections
Tempers like 7050-T7451 and T7651 are particularly suitable for large, thick-section profiles. They offer consistent mechanical properties throughout and resist performance degradation, outperforming 7075 in large-scale structural applications.
Good machinability
Despite its high strength, 7050 aluminum angle maintains good machinability after heat treatment, making it suitable for CNC machining and the assembly of complex structures.
Aerospace-grade approval
7050 aluminum is widely used by major aircraft manufacturers such as Boeing and Airbus. It is a certified material for aerospace structures, offering globally recognized quality and compliance with industry standards.

How to choose?
When deciding between 7050 and 7075 aluminum angles, consider the specific requirements of your application:
- Choose 7050 aluminum angle if your project involves high stress loads, thick-section structures, or corrosive environments. It offers better stress corrosion resistance and superior fatigue performance, making it ideal for aerospace, military, and long-term structural applications.
- Choose 7075 aluminum angle if maximum strength and weight reduction are your top priorities, especially in thin-section or machined components. It is a cost-effective choice for high-performance parts where corrosion resistance is not the primary concern.

7050 aluminum angle FAQs
What industries is 7050 aluminum angle used in?
7050 aluminum angle is widely used in aerospace, military structures, rail transit, engineering machinery, and precision equipment frames. Its high strength-to-weight ratio, excellent stress corrosion resistance, and long fatigue life make it a premium alternative to 7075, especially in high-load, thick-section, and high-demand structural applications.
How should 7050 aluminum angle be cut and machined?
Use rigid equipment such as carbide-tipped saw blades, CNC band saws, or machining centers. Due to its hardness, cutting tools must be sharp and the material should be securely clamped. Coolant is recommended to reduce heat. Bending should be carefully controlled to prevent cracking or springback.
Do you offer cutting and CNC machining services?
Yes. Chalco provides a range of machining services for 7050 aluminum angles, including precision cutting, drilling, tapping, chamfering, CNC milling, and end processing. Custom fabrication is available based on customer drawings to support aerospace and precision mechanical assemblies.
What factors affect the price of 7050 aluminum angle?
Pricing is influenced by:
- Raw material cost (aluminum ingot + alloying elements)
- Temper (e.g., T7451, T7651)
- Profile dimensions (leg length, wall thickness, length)
- Surface treatment (anodizing, electrophoresis, coating)
- Additional processing or customization (mold setup, CNC precision machining)
How is the weight of 7050 aluminum angle calculated?
Use the following steps:
- Density of 7050 aluminum ≈ 2.83 g/cm³
- Cross-sectional area A = (a × t) + (b × t) – t²
- Volume = A × length
- Weight = volume × density (convert to kg or lbs as needed for design or logistics)
Can 7050 aluminum angle be welded?
Welding is not recommended. Due to its high zinc and copper content, 7050 aluminum has poor weldability and is prone to hot cracking. If welding is necessary, special filler wires and techniques should be used, followed by heat treatment or structural reinforcement.
Can 7050 aluminum angles be customized?
Absolutely. Chalco offers custom fabrication of 7050 aluminum angles in equal leg, unequal leg, rounded corner, and non-90° configurations. Customizable parameters include length, angle, wall thickness, and hole positions to meet aerospace, defense, and precision industrial needs.
Is 7050 aluminum angle reliable for outdoor use?
7050 offers good corrosion resistance, especially in the T7451 temper, and outperforms 7075 in harsh conditions. For long-term outdoor use in marine, humid, or acidic environments, additional surface treatments such as anodizing or coating are recommended to enhance durability.
Can 7050 aluminum angle be anodized?
Yes. 7050 aluminum can undergo anodizing, electrophoretic coating, or hard coating processes. Although its anodized brightness is lower than 6xxx series alloys, it significantly improves surface hardness, corrosion resistance, and appearance, making it suitable for both structural and visible components.
