Overview
3003 aluminum is a commercially pure alloy with manganese added for increased strength, delivering approximately 20% more strength than 1100 grade. The H14 temper signifies it has been strain-hardened and partially annealed. This results in a material that is easy to form, drill, and weld. The raised diamond pattern provides excellent skid resistance and rigidity, making it a functional and durable choice for various applications.
Known for its excellent workability and weldability, 3003 diamond plate is a popular choice for general fabrication. While not heat-treatable like 6061 aluminum, its properties are ideal for applications not requiring high mechanical strength. The bright, reflective finish combined with the textured pattern provides a clean, modern aesthetic suitable for both protective and decorative uses, performing well in various environments without rusting.

- Marine: Decking, dock plates, and gangways - for its excellent corrosion resistance in wet environments.
- Food Service: Kitchen backsplashes and wall coverings - as it is easy to clean and resists corrosion.
- Commercial: Retail displays, counter fronts, and decorative trim - for its modern, industrial appearance.
Working with 3003 Aluminum Diamond Plate
Machining
3003 aluminum has fair machinability. It can be somewhat gummy compared to harder alloys like 6061. Use sharp tools, high speeds, and proper lubrication for best results. The diamond pattern may require secure clamping for precision work.
Welding
This alloy has excellent weldability using common methods like TIG (GTAW) and MIG (GMAW). AL4043 filler wire is typically recommended for best results and to minimize the risk of cracking.
Finishing
The material is supplied with a standard mill finish and a raised diamond pattern. It can be anodized for increased corrosion resistance and color options, or polished for a brighter, more reflective appearance.

Frequently Asked Questions
Q: What is the difference between 3003 and 6061 aluminum diamond plate?
A: 3003 is softer, more formable, and has better general corrosion resistance. 6061 is significantly stronger (45,000 PSI vs 22,000 PSI tensile strength) and is heat-treatable, making it suitable for structural applications where strength is critical.
Q: Can 3003 diamond plate be bent?
A: Yes, 3003-H14 has excellent formability and can be bent to a tight radius without cracking, making it ideal for custom fabrications like boxes, trays, and corner guards.
Q: Is the thickness measured from the base or the top of the diamond?
A: The specified thickness (e.g., 0.063") refers to the nominal thickness of the base plate material, not including the height of the raised diamond pattern.
