Description
Detailed Product Description-aluminum pipe supplier China
Gengfei supplies 2A16 aluminum round tubes in precision dimensions and multiple tempers for aerospace and industrial markets. As an aluminum-copper-magnesium alloy, 2A16 (equivalent to LY16 in China) offers superior thermal stability, fatigue performance, and mechanical strength, especially under elevated temperatures.
This alloy is heat-treatable and commonly used in structures requiring reliable mechanical properties after welding or machining. It exhibits good resistance to stress corrosion cracking, particularly in thick cross-sections or heavily loaded applications.

Frequently Asked Questions – 2A16 Aluminum Round Tube
Q1: How does 2A16 compare to 2024 aluminum?
A: 2A16 offers better heat resistance and thermal stability, while 2024 has slightly higher strength but lower performance under high temperatures.
Q2: Is 2A16 aluminum suitable for welding?
A: It can be welded, but post-weld heat treatment may be needed to restore strength. It is more crack-resistant than some other high-strength aluminum alloys.
Q3: What industries typically use 2A16 tubing?
A: Aerospace, energy equipment, railway, military hardware, and thermal structures.
Q4: Can 2A16 tubing be anodized or coated?
A: Yes. We offer mill finish, anodizing, and other surface treatments to improve corrosion resistance and appearance.
Q5: Do you provide test certificates?
A: Yes. Each order is delivered with full Mill Test Certificates and complies with Chinese (GB) or international (ASTM) standards.
