3003 aluminum sheet metal is a common type of aluminum alloy, belonging to the aluminum-manganese alloy series. It has good formability, corrosion resistance and weldability and is widely used in various industrial and commercial applications.
 
The main components of 3003 aluminum alloy include:
- Aluminum (Al): approximately 96.7% to 98.0
- Aluminum (Al): approximately 96.7 to 98.0 percent Manganese (Mn): approximately 1.0 to 1.5 percent
- Other elements such as copper (Cu), magnesium (Mg), silicon (Si), etc. in small amounts.

 
The specifications and states of 3003 aluminum sheet usually include:
- Thickness: generally ranges from 0.2mm to 100mm, depending on application requirements.
- Width and length: can be customized according to customer requirements, common width is 1000mm, 1200mm, 1500mm, etc., length is usually 2000mm, 2500mm, 3000mm, etc..
- Tempers: Common tempers are H14, H16, H18 (hard state) and O (soft state), different conditions correspond to different strength and ductility.
 
Performance characteristics of 3003 aluminum sheet metal are:
- Excellent formability: 3003 aluminum alloy has good workability and is easy to stretch, press and bend, so it is suitable for various forming processes.
- Good corrosion resistance: it has good corrosion resistance in many environments and is suitable for use in wet or corrosive environments.
- Weldability: 3003 aluminum alloy can be welded by a variety of welding methods, making it suitable for the manufacture of complex structures.
- Moderate Strength: Compared to other aluminum alloys, 3003 aluminum is moderately strong and can meet the needs of many applications.
 
3003 aluminum sheet metal is widely used in the following areas:
