What Is an 8mm Aluminium Plate?
An 8mm aluminium plate is a flat aluminium product with a nominal thickness of 8 millimeters. It is thicker than common aluminium sheet and offers a useful balance between weight, strength, corrosion resistance, and machinability.
This thickness is often selected for parts that need more rigidity than a thin sheet. It can be used for industrial equipment, transport parts, structural components, machine frames, tooling, marine applications, and custom fabricated products.
The final performance depends on the aluminium alloy, temper, surface finish, plate size, and processing method. For this reason, buyers should select the material based on the actual working conditions rather than thickness alone.
An 8mm plate can be supplied as a standard flat plate or cut to a specific length and width. CNC cutting, waterjet cutting, drilling, milling, bending, and other fabrication services can also be arranged for many grades.

8mm Aluminium Plate Alloy Options
Choosing the right alloy is one of the most important steps when buying aluminium plate. Different alloys offer different levels of strength, corrosion resistance, formability, and machinability.
1050 Aluminium Plate
1050 is a commercially pure aluminium alloy with high aluminium content. It has good electrical and thermal conductivity and is easy to form.
It is suitable for applications where very high strength is not required.

5052 Aluminium Plate
5052 is a popular aluminium-magnesium alloy. It has good corrosion resistance and good formability.
It is widely used in transport, marine, architectural, and industrial applications.
For buyers looking for a combination of corrosion resistance and moderate strength, 5052 is often a practical choice.
5083 Aluminium Plate
5083 aluminium is known for its strong corrosion resistance and good performance in marine environments.
It is commonly used for:
- Marine structures
- Shipbuilding
- Pressure equipment
- Transport equipment
- Welding structures

6082 Aluminium Plate
6082 is another common structural aluminium alloy. It offers good mechanical strength and good machinability.
It can be a suitable choice for structural components and industrial machinery where higher strength is needed.
8mm Aluminium Plate Temper Options
The temper describes the condition of the aluminium after processing. It can affect hardness, strength, forming performance, and machinability.
| Temper | General Characteristic |
|---|---|
| O | Soft and highly formable |
| H12 | Strain hardened, relatively soft |
| H14 | Medium hardness |
| H18 | Hard temper |
| H22 | Partially annealed |
| H24 | Partially annealed and hardened |
| H32 | Stabilized strain-hardened condition |
| T6 | Solution heat treated and artificially aged |
Not every temper is available for every alloy.
For example, 6061-T6 is commonly used when strength and machining performance are important. A softer O temper may be more suitable when forming is the main requirement.
8mm Aluminium Plate Size Guide
Standard and custom sizes can both be supplied.
| Size | Typical Use |
|---|---|
| 1000 × 2000 mm | Small fabrication |
| 1220 × 2440 mm | General industrial use |
| 1250 × 2500 mm | Fabrication and panels |
| 1500 × 3000 mm | Large components |
| 1500 × 6000 mm | Industrial projects |
| Custom size | CNC and project requirements |
The actual available size depends on the alloy and mill capacity.
Custom cutting can help reduce material waste. Buyers can provide drawings, cutting lists, or required dimensions for quotation.
8mm Aluminium Plate Weight
Weight is important when calculating shipping costs, structural loads, and material requirements.
The basic calculation uses aluminium density and plate volume.
For a simple estimate, aluminium has a density of about 2.7 g/cm³.
Common 8mm Plate Weight Examples
| Plate Size | Approximate Weight* |
|---|---|
| 1000 × 2000 mm | 43.2 kg |
| 1220 × 2440 mm | 64.3 kg |
| 1250 × 2500 mm | 67.5 kg |
| 1500 × 3000 mm | 97.2 kg |
| 1500 × 6000 mm | 194.4 kg |
*Approximate theoretical weight based on 2.7 g/cm³. Actual weight can vary because of dimensional tolerance and alloy density.
A simple formula is:
Weight ≈ Length × Width × Thickness × Density
When dimensions are in meters and density is in kg/m³:
Weight ≈ L × W × 0.008 × 2700
This calculation can be used for preliminary purchasing and shipping estimates.
8mm Aluminium Plate vs Aluminium Sheet
The words “sheet” and “plate” can vary by market and standard. Thickness is one of the main factors used to distinguish the two.
| Feature | Thin Aluminium Sheet | 8mm Aluminium Plate |
|---|---|---|
| Thickness | Usually thinner | 8mm |
| Rigidity | Lower | Higher |
| Weight | Lower | Higher |
| Structural use | Limited | More suitable |
| Machining | Easy | Suitable for machining |
| Forming | Usually easier | Depends on alloy and temper |
| Heavy equipment | Less suitable | More suitable |
An 8mm product is often chosen when a project needs a more rigid aluminium component.
8mm Aluminium Plate vs Steel Plate
Aluminium and steel are used for many of the same industrial purposes, but they have different properties.
| Property | Aluminium | Steel |
|---|---|---|
| Density | About 2.7 g/cm³ | About 7.85 g/cm³ |
| Weight | Lower | Higher |
| Corrosion resistance | Generally good | Depends on grade and coating |
| Machining | Generally easy | Depends on grade |
| Thermal conductivity | High | Lower |
| Magnetic | Non-magnetic | Many grades are magnetic |
| Surface oxidation | Protective oxide layer | Can rust without protection |
The lower density of aluminium can be valuable when weight reduction is important.
Steel has preferred when very high strength, stiffness, or lower material cost is the main concern.

How to Choose the Right 8mm Aluminium Plate
A simple purchasing process can prevent many material problems.
Start With the Application
First identify where the plate will be used.
Ask:
- Is it structural?
- Will it be exposed to water?
- Does it need welding?
- Will it be CNC machined?
- Does it need bending?
- Is appearance important?
- Is low weight important?
The answers help narrow down the alloy.
Select the Alloy
Do not select an alloy based only on price.
For example:
General fabrication → 1050 / 1060 / 3003
Corrosion resistance → 5052 / 5083
Marine use → 5083
CNC machining → 6061 / 6082
Select the Temper
The temper should match the manufacturing process.
A soft temper can be useful for forming. A harder temper may be better when strength is needed.
Confirm the Dimensions
Provide the supplier with:
- Thickness
- Width
- Length
- Quantity
- Alloy
- Temper
- Surface finish
- Cutting requirements
This allows the supplier to prepare a more accurate quotation.
Custom 8mm Aluminium Plate Supply
Many projects do not use standard plate sizes.
Custom service can include:
Raw plate → Cutting → CNC processing → Drilling → Surface treatment → Inspection → Packing
Custom sizes can reduce cutting work at the customer’s factory.
For large projects, buyers may also request fixed sizes for each production batch. This can make production and material planning easier.
