Aluminium Sheet

Aluminium sheet with 4 mm 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: 4 mm.
• 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 4 mm 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’ (1220 mm x 2440 mm), 5’ x 10’ (1525 mm x 3050 mm).
• 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 kg Weight=1.22×2.44×0.004×2700≈31.91 kg

5. Properties:

• Lightweight: Roughly 1/3 the weight of steel.
• Corrosion Resistance: Highly resistant to corrosion in most environments.
• Thermal and 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.
• Industrial: Machinery components, storage tanks and electrical panels.
• Decorative Uses: Interior designs and furniture.

7. Customization Options:

• Coating: Anodizing for enhanced corrosion resistance and aesthetic appeal.
• Perforation: For ventilation or decorative purposes.
• Patterned or Textured Surfaces: For anti-slip or aesthetic functions.
