A 1/4 aluminum plate (also written as one quarter inch aluminum plate) is a strong, lightweight, and corrosion-resistant material widely used in construction, machinery, vehicles, and marine industries. Its balance of strength and formability makes it suitable for both structural and decorative applications.
Aluminum plates at this thickness (6.35mm) are available in different alloys such as 5052, 6061, and 3003, each providing unique mechanical and corrosion-resistant properties.

How to Choose the Right 1/4 Aluminum Plate
When selecting a 1/4 inch aluminum plate, consider:
- Alloy: Choose 6061-T6 for strength, or 5052 for corrosion resistance.
- Finish: Mill finish for general use, anodized for decoration, painted for outdoor applications.
- Size: Standard 4×8 feet or custom cut sizes available.
- Quantity: Bulk orders often have better pricing per kg.
Typical Price Range
| Alloy | Price per Kg (USD) | Price per Sheet (4×8 ft) |
|---|---|---|
| 3003 | $2.20–$2.50 | $170–$190 |
| 5052 | $2.80–$3.10 | $200–$230 |
| 6061 | $3.20–$3.60 | $240–$270 |
| 5083 | $3.40–$3.90 | $260–$300 |
Prices may vary based on market aluminum ingot prices and order volume.
