6mm Aluminum Plate: A Versatile Metric Mid-Gauge for Fabrication and Structural Applications
6mm aluminum plate is one of the most commonly used medium-thickness aluminum products in global fabrication markets. With a thickness of approximately 0.236 inches, it is slightly thinner than the standard 1/4-inch aluminum plate used in many imperial measurement systems.
Because it provides a good balance between strength, weight, machinability, and cost efficiency, 6mm aluminum plate is widely selected for equipment panels, transportation components, marine structures, CNC machining parts, and industrial fabrication projects.
For different applications, buyers usually choose different aluminum alloys. 5083-H321, 6061-T651, 5754-H111, and 5052-H32 are among the most frequently specified grades for this thickness range.
Why 6mm Aluminum Plate Is Widely Used
A 6mm thickness provides more rigidity than thin aluminum sheets while remaining easier to process than heavy aluminum plates. It can be cut, drilled, welded, bent, and machined with standard fabrication equipment.
| Feature | 6mm Aluminum Plate | Fabrication Advantage |
|---|---|---|
| Thickness | 6mm (0.236") | Balanced strength and weight |
| Weight | About 16.2kg/m² | Lower weight than steel plate |
| Common Width | 1000-2000mm | Suitable for CNC and cutting |
| Processing | Laser cutting, waterjet, milling | Flexible manufacturing options |
Popular Aluminum Grades for 6mm Plate
The correct alloy selection depends mainly on strength requirements, corrosion environment, and manufacturing method.
| Alloy & Temper | Main Characteristics | Typical Applications |
|---|---|---|
| 5083-H321 | Excellent corrosion resistance and marine performance | Ship structures, marine equipment, tanks |
| 6061-T651 | High strength, excellent machining stability | CNC parts, tooling plates, machine bases |
| 5754-H111 | Good formability and corrosion resistance | Automotive parts, structures, panels |
| 5052-H32 | Good welding performance and corrosion resistance | General fabrication, enclosures |
6mm Aluminum Plate Weight Calculation
The weight of aluminum plate can be calculated using the formula:
Weight = Thickness × Width × Length × Aluminum Density
Using aluminum density of approximately 2.7g/cm³:
| Plate Size | Approximate Weight |
|---|---|
| 1m × 2m × 6mm | About 32.4kg |
| 4ft × 8ft × 6mm | About 68lbs |
6mm Aluminum Plate Cutting and Fabrication
Because aluminum has high thermal conductivity and reflects laser energy differently from carbon steel, processing parameters must be adjusted carefully. Fiber laser cutting is commonly used for precision shapes, while waterjet cutting is preferred when heat influence must be minimized.
| Processing Method | Advantages | Suitable Applications |
|---|---|---|
| Fiber Laser Cutting | Fast cutting and accurate edges | Sheet metal fabrication |
| Waterjet Cutting | No heat affected zone | Precision components |
| CNC Machining | High dimensional accuracy | Mechanical parts |
6mm vs 5mm vs 8mm Aluminum Plate Selection
| Thickness | Strength Level | Recommended Use |
|---|---|---|
| 5mm | Medium | Light equipment panels and covers |
| 6mm | Medium-high | General structures and fabrication parts |
| 8mm | Higher | Heavy-duty structures and machining bases |
Typical Applications of 6mm Aluminum Plate
- Industrial equipment covers and protective panels
- CNC machine bases and tooling components
- Marine cabins, decks, and structural parts
- Vehicle body panels and transportation equipment
- Electrical cabinets and fabricated enclosures

Frequently Asked Questions About 6mm Aluminum Plate
Q1: Is 6mm aluminum plate the same as 1/4 inch aluminum plate?
No. 6mm aluminum plate is approximately 0.236 inches, while 1/4 inch equals 6.35mm. They are close but not identical.
Q2: What is the best alloy for 6mm aluminum plate?
It depends on the application. 6061-T651 is preferred for machining, 5083-H321 for marine environments, and 5052-H32 for general fabrication.
Q3: Can 6mm aluminum plate be laser cut?
Yes. Fiber laser cutting is commonly used for 6mm aluminum plate when proper power settings and cutting parameters are applied.
Q4: How much does a 6mm aluminum plate weigh?
A 1m × 2m plate weighs approximately 32kg, depending on the exact alloy density and dimensional tolerance.
