2219 Aluminum Bar
2219 Aluminum Bar is a high-strength, heat-treatable aluminum-copper alloyfrom the 2000 series, renowned for its exceptional strength at elevated temperatures, superior weldability, and excellent performance in cryogenic environments. With a copper content of 5.8–6.8%and additions of manganese (0.2–0.4%), vanadium (0.05–0.15%), and zirconium (0.1–0.25%), this alloy delivers outstanding mechanical propertieswhile maintaining good fracture toughness and stress corrosion resistance. Widely used in aerospace, automotive manufacturing, and other fields.
| Characteristics | Description |
High-Temperature Resistance |
The 2219 Aluminum Alloy Round Bar performs excellently under extreme temperature conditions, maintaining mechanical integrity in environments ranging from -452°F to 600°F (-269°C to 315°C). This characteristic makes it particularly suitable for applications that are highly sensitive to temperature variations, such as spacecraft structures, rocket engine combustion chamber liners, and high-temperature liquid transport systems. Its high-temperature strength comes from its primary alloying element, copper (Cu), ensuring excellent structural stability and creep resistance in high-temperature environments while maintaining sufficient toughness at extremely low temperatures, making it suitable for cryogenic propellant storage tanks. |
Corrosion Resistance |
The 2219 Aluminum Round Alloy Bar has moderate corrosion resistance and is particularly susceptible to corrosion in marine or high-humidity environments. Therefore, additional surface treatments are usually required to enhance its corrosion resistance. Common methods include anodizing, electrophoretic coating, or chromate treatment to form a dense protective film that improves oxidation resistance. These treatment processes make it suitable for aircraft fuselage structures, fuel tanks, and spacecraft components, ensuring stable mechanical properties and structural integrity over long service periods. |
Fatigue Resistance |
The 2219 Aluminum Alloy Round Bar exhibits excellent fatigue resistance, allowing it to withstand long-term cyclic loads without fatigue failure. This property is crucial in aerospace applications, especially in aircraft skins, wing structures, and landing gear attachments that endure repeated stress, effectively extending their service life. Its high fatigue resistance stems from its uniform microstructure and well-balanced alloy composition, providing better crack propagation resistance under cyclic loads, ensuring reliability and safety in high-strength working environments. |
