3003 Aluminum Plates
3003 Aluminum Plates
3003 Aluminum is the most widely used of all aluminum alloys. It is essentially commercially pure aluminum with the addition of manganese, which increases strength while maintaining low weight. Plates are defined as material over 0.250 inches thick and are most often used for heavy-duty applications. It has excellent corrosion resistance and workability, and it may be deep drawn or spun, welded, or brazed. This alloy is non-heat treatable.
- 3003 Aluminum (UNS A93003)
- Manganese alloy
- Non-heat treatable
- Excellent corrosion resistance
- Good weldability & formability
Overview
3003 Aluminum Plates represent the industry standard for a versatile, high-strength, and non-heat-treatable aluminum alloy. As the most widely used aluminum alloy, 3003 is essentially commercially pure aluminum with the addition of manganese. This key addition significantly enhances the strength while maintaining the material's characteristically low weight. Plates, defined as material over 0.250 inches thick, are engineered for heavy-duty applications where durability and reliability are paramount.
Technical Overview
3003 aluminum is part of the 3xxx series, known for its excellent manganese content. This alloy is not heat-treatable; its strength is derived from strain hardening (H-series tempers). It offers a superb combination of strength, formability, and corrosion resistance, making it a go-to choice for engineers and fabricators across numerous industries.
Applications
The robustness of 3003 aluminum plates makes them ideal for a vast range of applications. They are commonly used in chemical equipment, storage tanks, pressure vessels, and architectural components like gutter systems. Their excellent workability allows for deep drawing, spinning, welding, and brazing, enabling complex fabrications.
Advantages
The primary advantages of choosing 3003 aluminum plates include their superior resistance to corrosion, particularly in industrial and marine environments. The material is highly malleable and can be easily formed into complex shapes. Its weldability and brazeability are excellent, and it possesses good thermal and electrical conductivity. For B2B buyers, this translates to a reliable, cost-effective material that simplifies fabrication and ensures long-term performance in demanding conditions.

How to Measure & Order
Specify 3003 aluminum plates by providing:
1.) Alloy (3003)
2.) Temper (e.g., H14)
3.) Thickness (in inches or mm)
4.) Width
5.) Length. Tolerances should be specified if tighter than standard. For non-rectangular shapes, provide a detailed drawing (DXF, DWG). Contact our technical sales team for complex orders.
