An Aluminium Sheet with 4mm Thickness is a versatile material used across various industries due to its lightweight, corrosion resistance, and ease of fabrication. Below are its key details:
1. General Characteristics:
- Thickness: 4mm.
- Material: Aluminium, known for being lightweight yet strong, with excellent thermal and electrical conductivity.
- Surface Finish: Available in mill finish, brushed, anodized, or powder-coated finishes.
2. Common Alloys for 4mm Aluminium Sheets:
- Alloy 1050: High purity, excellent corrosion resistance, and good for general applications.
- Alloy 5052: Superior corrosion resistance, higher strength, and weldable; ideal for marine applications.
- Alloy 6061: High strength, good corrosion resistance, and machinable; suitable for structural uses.
- Alloy 7075: High strength, often used in aerospace and automotive industries.
3. Dimensions:
- Standard Sizes:
- 4’ x 8’ (1220mm x 2440mm)
- 5’ x 10’ (1525mm x 3050mm)
- Custom Cuts: Sheets can be cut to specific sizes as per requirements.
4. Weight Calculation (Approximate):
- Formula:Weight (kg)=Length (m)×Width (m)×Thickness (m)×Density (kg/m3)Weight (kg)=Length (m)×Width (m)×Thickness (m)×Density (kg/m3)
- Aluminium density: ~2,700 kg/m³.
- Example for a 4' x 8' sheet (1220mm x 2440mm):Weight=1.22×2.44×0.004×2700≈31.91 kgWeight=1.22×2.44×0.004×2700≈31.91kg
5. Properties:
- Lightweight: Roughly 1/3 the weight of steel.
- Corrosion Resistance: Highly resistant to corrosion in most environments.
- Thermal & Electrical Conductivity: High conductivity, ideal for heat sinks and electrical applications.
- Workability: Easy to cut, bend, and weld.
6. Applications:
- Construction: Cladding, roofing, partitions, and facades.
- Transportation: Vehicle bodies, trailers, and aerospace components.
- Signage: Boards and hoardings.
