Product Details
A 5mm aluminium sheet refers to an aluminum flat product with a nominal thickness of 5 millimeters, commonly used in structural, industrial, and fabrication applications. Thickness is one of the most important parameters because it directly determines weight, strength, processing method, and application range.
What Does 5mm Thickness Mean?
The “5mm” refers to the actual material thickness after rolling and finishing.
This thickness is considered:
- Medium-thick aluminum sheet
- Suitable for structural and mechanical applications
- Strong enough for load-bearing fabrication
Common Standard Sizes of 5mm Aluminium Sheet
Although thickness is fixed at 5mm, width and length can vary depending on production and customer requirements.
Typical sheet dimensions:
| Thickness | Width Range | Length Range |
|---|---|---|
| 5mm | 1000 mm – 2000 mm | 2000 mm – 6000 mm |
Common Standard Formats
1. Standard Sheet Format
- 1000 × 2000 mm
- 1250 × 2500 mm
- 1500 × 3000 mm
2. Large Plate Format
- 2000 × 4000 mm
- 2000 × 6000 mm
3. Custom Cut Sizes
- CNC cutting available
- Laser or shear cutting based on requirement
- Used for engineering and fabrication projects
Why 5mm is a Common Thickness
5mm aluminium sheet is widely used because it offers a balanced performance:
- Stronger than thin sheets (1–3mm)
- Easier to process than thick plates (≥10mm)
- Suitable for welding, bending, and machining
Thickness Tolerance in Production
Industrial aluminium sheets typically have controlled tolerance ranges:
- Cold rolled sheet: ±0.05 mm to ±0.15 mm
- Hot rolled plate: slightly wider tolerance range
This ensures:
- Stable assembly performance
- Accurate engineering fit
- Consistent product quality
Weight Reference of 5mm Aluminium Sheet
Weight depends on alloy density, but a general reference:
So:
- 1 square meter ≈ 13.5 kg
- Larger sheets increase proportionally
Typical Applications Based on Thickness
5mm aluminium sheet is commonly used for:
- Machine base plates
- Structural brackets
- Marine components
- Transportation panels
- Industrial enclosures
- Construction support parts
