Core Performance

2024 Aluminum Sheet

High Strength: It exhibits outstanding strength at room temperature and can withstand significant external forces, making it suitable for applications requiring high structural strength.

Controllable Processability: It has excellent formability in the hot, annealed, and freshly quenched states, allowing for complex shapes through processes such as forging and stamping. Heat treatment can significantly strengthen the aluminum, but strict control of heat treatment parameters is required.

Stable Heat Resistance: 2024 alloy maintains stable performance in environments below 150°C, making it suitable for manufacturing components with certain temperature requirements.

Weak Corrosion Resistance: Susceptible to corrosion in humid, acidic, and alkaline environments, surface treatments such as aluminum cladding is needed to enhance corrosion resistance.

3105 Aluminum Sheet

Excellent Rust Resistance: As a commonly used rust-resistant aluminum, it offers strong corrosion resistance in normal atmospheric environments and can withstand most outdoor or humid environments without complex surface treatment.

Excellent Plasticity: It exhibits extremely high plasticity in the annealed state and maintains good plasticity even in the semi-cold-hardened state, making it easily adaptable to cold working operations such as bending and stretching, facilitating the production of complex shapes.

Strong Machinability: While its machinability is average, en aw 3105 can meet general machining requirements by adjusting machining parameters. It also offers excellent weldability, enabling stable welds using common methods such as arc welding, facilitating component assembly.

Medium Conductivity: Due to its approximately 0.3% copper content, its conductivity can reach 41%. It can be used in applications where basic, but not extreme, electrical conductivity is required.
