3003 aluminum sheet belongs to the aluminum-manganese alloy series and is a common non-heat-treatable alloy. Due to its excellent anti-rust properties, it is also known as a rust-proof aluminum sheet. This characteristic mainly stems from its manganese alloy content (about 1.0-1.5%). Compared to pure aluminum (such as 1100 aluminum alloy), the strength of 3003 aluminum sheet is approximately 20% higher while maintaining good formability and corrosion resistance.
3003 aluminum sheet is a cost-effective and versatile aluminum alloy product, performing exceptionally in decorative, structural, and anti-rust application scenarios. It is an indispensable basic material in both industrial and civil fields.
Anti-Rust Performance
The oxidation and corrosion resistance of 3003 aluminum sheet is excellent, especially in humid environments or where weak acidic and alkaline media are present.
Strength and Toughness
The strength of 3003 aluminum sheet is higher than that of 1100 aluminum sheet while maintaining good toughness, making it suitable for applications requiring both strength and flexibility.
Workability
It has high workability and good formability, making it easy to perform various processing operations such as stamping, drawing, and bending.
Weldability
This material can be connected using various welding methods (such as gas welding and resistance welding) with stable welding performance.
Anodizing Performance
During anodizing, 3003 aluminum sheet may exhibit slight discoloration but responds well to mechanical finishing and organic coating treatments.
3003 aluminum is easily welded and brazed, but welding is limited to torch methods.
It is worth noting that 3003 aluminum alloys tend to become viscous when machined, but will perform satisfactorily at higher temperatures with proper settings and maximum speeds.
