Aluminum plate is a flat-rolled aluminum product selected for applications requiring low weight, corrosion resistance, dimensional stability, machinability or structural strength.
Compared with thin aluminum sheet, aluminum plate is more commonly used for:
CNC-machined components
Machinery bases and equipment panels
Marine structures and shipbuilding
Transportation frames
Aerospace structural components
Moulds, fixtures and tooling
Pressure vessels and storage tanks
Heavy-duty industrial fabrication
The terms "aluminum sheet" and "aluminum plate" are sometimes used differently between markets. Many buyers use "sheet" for thinner material and "plate" for thicker flat products. To avoid purchasing errors, the inquiry and purchase order should always state the exact thickness, alloy, temper and applicable standard.
Xi'an Dongmeng Group Co., Ltd. supplies aluminum alloy plate for global distributors, OEM manufacturers, engineering companies, machining factories and project contractors. Cut-to-size processing, technical document review, inspection coordination and export packaging are available.

Aluminum Plate Weight Calculation
The approximate weight of aluminum plate can be calculated using:
Weight (kg) = Thickness (mm) × Width (mm) × Length (mm) × Density × 10⁻⁶
For general calculations, an approximate aluminum density of 2.70 g/cm³ is commonly used.
Example:
10 mm × 1500 mm × 3000 mm aluminum plate:
10 × 1500 × 3000 × 2.70 × 10⁻⁶ = 121.5 kg per plate
Actual weight may vary slightly according to alloy composition, dimensional tolerance and measured dimensions.

FAQ – Aluminum Plate
1. What is the difference between aluminum sheet and aluminum plate?
The distinction is usually based on thickness and market convention. Thin flat-rolled products are commonly called sheet, while thicker products are commonly called plate. Because terminology varies, buyers should always specify exact thickness, alloy, temper and standard.
2. Which aluminum plate grade is best for CNC machining?
6061-T651 is widely selected for general CNC machining because it offers balanced strength, corrosion resistance, machinability and dimensional stability. For higher strength, 2024-T351 or 7075-T651 may be considered.
3. Which aluminum plate is suitable for marine use?
5083-H116, 5083-H321 and 5086 marine aluminum plates are commonly selected for shipbuilding, offshore structures and seawater applications because of their corrosion resistance and weldability.
4. What is the difference between 6061-T6 and 6061-T651?
Both conditions are solution heat-treated and artificially aged. T651 material is additionally stress-relieved by stretching, making it more suitable for thick plates and parts requiring extensive CNC machining.
5. Is 7075 aluminum plate stronger than 6061?
7075 generally provides substantially higher strength. However, 6061 normally offers better weldability, easier fabrication and good general corrosion resistance. The correct material depends on the application rather than strength alone.
6. Can you supply ASTM B209 aluminum plate?
Yes. Aluminum plate can be supplied according to ASTM B209/B209M, subject to the alloy, temper, dimensions and required edition of the standard.
7. Can aluminum plate be cut to custom sizes?

8. Can you provide ultrasonic-tested aluminum plate?
Ultrasonic inspection can be arranged for specified aerospace, tooling or critical thick-plate applications. The required test standard, inspection class, acceptance criteria and reporting format must be confirmed before quotation.
9. Can aluminum plate be welded?
Weldability depends on the alloy and temper. 5xxx- and 6xxx-series aluminum alloys generally provide better welding performance. Fusion welding is normally not preferred for primary high-strength structures made from 2024, 7050 or 7075 unless approved by the responsible engineer.
10. What affects the price of aluminum plate?
Price is affected by alloy, temper, thickness, plate size, order quantity, tolerance, testing level, certification, cutting, machining, surface protection, packing and destination.
11. Can you provide MTC 3.1?
Yes. Mill test documentation and EN 10204 3.1 certificates can be supplied when specified in the purchase order and confirmed before production.
