Aluminum alloy 3003 is a commonly used aluminum alloy composed primarily of aluminum, manganese, and other minor elements. The addition of manganese improves the alloy's strength and corrosion resistance, making 3003 aluminum alloy widely used in numerous fields. In addition to its excellent mechanical properties, 3003 also offers excellent machinability and weldability, enabling it to be fabricated into complex shapes.

Frequently Asked Questions
Q: What is the difference between 3003 and 1100 aluminum?
A: 3003 contains manganese (1.0-1.5%), which provides about 20% higher strength than 1100 while maintaining good formability.
Q: Can 3003 aluminum be anodized?
A: Yes, 3003 can be anodized, but the manganese content may result in a darker, grayish appearance compared to pure aluminum.
Q: What is the maximum service temperature?
A: 3003 Aluminum Alloy can be used in continuous service up to 200°C (392°F) without significant loss of properties.
Q: Is 3003 suitable for marine environments?
A: While it offers good corrosion resistance, for severe marine applications, alloys like 5052 or 5086 are more appropriate.
Q: Do you provide custom tempers?
A: Yes, we can provide various tempers from O (annealed) to H18 (full hard) to meet your specific requirements.
