Applications of 7075 Aluminum Angle

Aerospace Industry

Standard: AMS-QQ-A-200/11

With its high tensile strength (up to 560 MPa) and lightweight properties, 7075 Aluminum Angle is widely used in aircraft fuselage frames, wing support structures, and rocket booster components. It reduces weight under extreme loads while meeting demanding fatigue resistance standards.

Military Industry

Used in armored vehicle frames, missile launcher structures, and other key components. Its excellent impact resistance enhances mobility and battlefield survivability. Surface coating technologies are often applied to improve corrosion resistance in humid or marine environments.

Industrial Machinery

Applied in robot joints, stamping press supports, and similar mechanical structures, 7075 angles offer structural stability under repeated stress. Their excellent machinability makes them suitable for complex parts, although due to poor weldability, mechanical fastening (e.g., riveting or bolting) is preferred.

Sports Equipment

Used in high-performance bicycle frames, racing chassis, and climbing gear, 7075 Aluminum Angle provides near-steel strength while reducing weight. For example, key bike joints can be 30% lighter. Mechanical joints are preferred over welding to avoid weld defects.

Transportation Sector

Standard: AMS-QQ-A-200/11

Ideal for modified car chassis, lightweight rail car bodies, and marine reinforcements, 7075 Aluminum Angle replaces steel to reduce energy consumption. In marine environments, anodizing is essential to prevent salt spray corrosion.

Electronics & Drones

Commonly used in drone arms and optical equipment mounts, the low density and high rigidity of 7075 Aluminum Angle balance strength with endurance. For example, drone arms for racing applications can withstand high-speed impact while minimizing battery load.

FAQ

1. Do you offer cutting and CNC machining services?

Yes, we provide full CNC machining services including cutting, drilling, milling, welding, and assembly for 7075 aluminum angles. Custom secondary processing is available based on project requirements.

2. What factors affect the price of 7075 aluminum angle?

The price depends on multiple variables such as:

• Raw material costs
• Product dimensions and tolerances
• Heat treatment process
• Extrusion die cost

Due to the high strength and complex alloy composition, 7075 aluminum tends to be priced higher than standard aluminum grades.

3. Can I customize 7075 aluminum angle?

Absolutely. We support customization for dimensions, surface treatments, and machining options. While custom production may incur higher initial costs, it ensures perfect fit and performance for specialized applications.

4. What are the advantages of 7075 aluminum angle over steel angles?

7075 aluminum angle offers:

• Much lighter weight
• Excellent corrosion resistance
• Higher strength-to-weight ratio

It is ideal for aerospace and high-performance applications, although it is generally more expensive than steel.

5. How do I calculate the weight of 7075 aluminum angle?

To estimate weight:

a. Use density = 2.81 g/cm³

b. Measure the width of both legs (a, b) and thickness (t)

c. Calculate area: A = (a × t) + (b × t) – t²

d. Multiply by extrusion length to get volume

e. Volume × density = weight (convert to kg if needed)

This ensures accuracy for design and shipping.

6. How is 7075 aluminum angle connected in assemblies?

Common methods include:

• Welding (requires specialized techniques)
• Brazing
• Mechanical fastening (bolts, rivets)

Due to lower weldability, mechanical joining is often preferred for structural reliability.

7. What is the best way to cut and bend 7075 aluminum angle?

For cutting, use band saws or miter saws with suitable blades to achieve clean cuts.

For bending, a precision press brake is recommended. Avoid bending after surface treatments like anodizing, as it may cause micro-cracks.

8. What causes cracking in 7075 aluminum angle?

7075 contains copper, which boosts strength but reduces corrosion resistance. In humid or marine environments, stress corrosion cracking may occur along grain boundaries. Proper coatings or anodizing are recommended to prevent this.
