Product Characteristics
Machinability
It has excellent machinability, facilitating easy forming and processing. In the annealed state, it can be readily cold-worked and hot-worked, adapting to various processing techniques such as stamping, forging, welding, etc.
Weldability
It features outstanding weldability. Thinner sections can be welded using Gas Tungsten Arc Welding (GTAW), while thicker sections are suitable for Gas Metal Arc Welding (GMAW).
Corrosion Resistance
A thin passivated oxide film forms on the surface, protecting the metal from further corrosion. It exhibits strong corrosion resistance, making it suitable for various harsh environments.
Strength and Hardness
It has high strength and hardness, resisting deformation after processing. The material is dense without defects, capable of withstanding significant external forces.
Appearance Effect
It is easy to polish and color, with excellent anodizing results, enabling rich and diverse colors and good gloss to enhance product aesthetics.
Environmental Friendliness
Aluminum is an eco-friendly material that can be recycled without generating pollution during the recycling process, meeting the requirements of sustainable development.
Chemical Composition
○ Aluminum (Al): Balance, the primary component of the aluminum coil.
○ Silicon (Si): 0.40%-0.8%. Improves alloy strength, hardness, casting performance, and weldability.
○ Copper (Cu): 0.15%-0.40%. Enhances strength and hardness, but excessive amounts reduce corrosion resistance.
○ Magnesium (Mg): 0.8%-1.2%. Forms Mg₂Si phase with silicon to significantly boost strength and hardness while maintaining good corrosion resistance.
○ Zinc (Zn): ≤0.25%. Provides auxiliary strengthening in the alloy.
○ Manganese (Mn): ≤0.15%. Improves strength, hardness, and corrosion resistance.
○ Titanium (Ti): ≤0.15%. Refines grain structure, enhancing strength and toughness.
○ Chromium (Cr): 0.04%-0.35%. Contributes to corrosion and oxidation resistance.
○ Iron (Fe): 0.000%-0.700%. Excessive content degrades alloy performance and is typically controlled within specified limits.
Mechanical Properties
● Tensile Strength: Varies with temper. For example:
○ In T6 temper: ≥310MPa
○ In O temper: ≤147MPa
● Yield Strength:
○ In T6 temper: ≥276MPa
○ In O temper: ≤55MPa
● Elongation:
○ In T6 temper: δ5 (%) ≥10%
○ In O temper: δ10 (%) ≥12%
