7075 Aluminum Flat Bar Applications
| Application | Description |
| Aerospace | 7075 aluminum flat bars are widely used in the aerospace industry for manufacturing various structural components. Their exceptional strength and good corrosion resistance make them ideal for producing wing beams, fuselage frames, and tail structures. The material's low weight without compromising strength ensures stable performance under high load and high-stress environments, guaranteeing structural safety and long-term durability of the aircraft. |
| Military | In military applications, 7075 aluminum flat bars are extensively used to produce high-strength and lightweight components, such as structural elements of armored vehicles and other tactical vehicles. Their excellent strength-to-weight ratio enhances armor protection while maintaining a low weight, contributing to improved mobility and durability of military equipment. Additionally, their corrosion resistance ensures reliable performance in harsh environments. |
| Automotive | 7075 aluminum flat bars are widely applied in the high-performance automotive sector, particularly for manufacturing frames and suspension components. They effectively reduce weight while enhancing structural strength. These components must withstand significant impact forces, vibrations, and high-speed pressures. The exceptional strength and light weight of 7075 aluminum make it an ideal choice for racing and performance vehicles, improving handling and safety. |
| Industrial | In industrial applications, 7075 aluminum flat bars are commonly used in high-stress machinery, fixtures, and tooling. Due to their superior strength, they provide reliable support for demanding mechanical equipment. Their lightweight properties also facilitate ease of operation and reduce equipment loads. Additionally, the stability and durability of 7075 aluminum flat bars make them a preferred choice for precision industrial manufacturing. |
| Sports | 7075 aluminum flat bars are extensively used in sports equipment, including bicycle frames and climbing gear, where high strength is crucial. Their lightweight and durable characteristics allow athletes to reduce unnecessary weight while ensuring durability and stability during activities. The material's excellent impact absorption capability ensures that sports equipment can withstand external forces during high-intensity use, providing safety for athletes. |
7075 Aluminum Flat Bar Manufacturing and Processing
- Weldability: Poor; prone to cracking (use 4043 filler if necessary).
- Machinability: Excellent (comparable to free-machining brass).
- Forming: Best performed in the annealed (O temper) condition.
- Heat Treatment: T6 temper (solution heat treated and artificially aged).
Standards and Certifications
- ASTM B209 (Standard Specification).
- AMS 4045 (Aerospace Material Specification).
- MIL-A-22771 (Military Specification).
Comparison Between 7075 Aluminum Flat Bar and 6061 Aluminum
- Strength: 7075 is approximately 30% stronger than 6061-T6.
- Corrosion Resistance: 6061 offers better corrosion resistance than 7075 in most environments.
- Cost: Due to its alloy composition, 7075 is generally more expensive.
Considerations:
While 7075 aluminum exhibits excellent mechanical properties, its corrosion resistance is lower compared to other aluminum alloys like 6061. Additionally, it is not easy to weld; welding can reduce its strength, making it generally not recommended for welded applications. However, it is machinable, though its hardness requires the use of appropriate tools for effective machining.
