High-Performance 2124 Aluminum Plate for Aerospace and Precision Engineering
The 2124 aluminum plate is a high-purity version of the classic 2024 alloy, specifically engineered to provide enhanced fracture toughness and elevated temperature strength. As a copper-based alloy, 2124 is primarily used in the aerospace industry where superior resistance to fatigue and crack growth is critical.
Through optimized chemical composition and advanced heat treatment (such as T851 tempering), our 2124 aluminum sheets offer excellent mechanical stability and stress-corrosion resistance. It is the preferred material for structural components subjected to high tension and cyclic loading.

FAQ
Q1: What is the difference between 2024 and 2124 aluminum?
A: 2124 is a higher-purity version of 2024. It has stricter controls on Silicon and Iron content, which results in much higher fracture toughness and better reliability in critical aerospace applications.
Q2: Can 2124 aluminum be welded?
A: Generally, 2124 is considered difficult to weld using traditional fusion welding methods due to its high copper content (cracking risk). It is typically joined using mechanical fasteners or specialized friction stir welding.
Q3: What is the most common temper for 2124?
A: T851 is the most common temper, as it provides the best balance of high strength, stability, and resistance to stress corrosion cracking.
Q4: Do you provide MTC (Material Test Certificates)?
A: Yes, all shipments are accompanied by a Mill Test Certificate according to EN 10204 3.1, ensuring compliance with aerospace standards.
