4mm aluminum plate weight calculation formula

Weight (kg) = length (m) × width (m) × 4 (mm) × 2.7 g/cm³ (aluminum density)

Weight for Common Sizes

• 1m×1m: Weight=10.8kg.
• 1m×2m: Weight=21.6kg.
• 1.2m×2.4m: Weight=31.1kg.
• 2m×3m:Weight=64.8kg.

Common grades of 4mm aluminum sheet

• 1050: 99.5% pure aluminum, often suitable for folding/bending/cold forming, semi-hard, excellent corrosion resistance.
• 2024: Aluminum-copper alloy, good toughness and fatigue resistance, general corrosion resistance, heat treatable. Use a temperature less than 65°C.
• 3003: Manganese alloy, medium strength, good machinability, weldable.
• 5052: Magnesium alloy, high strength, excellent marine corrosion resistance.
• 5083: Also called N8, excellent corrosion resistance in extreme environments, good weldability, non-heat treatable. Use temperature
• 6061: Heat treatable, structural grade, high strength, machinable and weldable.
• 6082: Also known as H30. Medium strength, excellent corrosion resistance. The highest strength in the 6000 series.
• 7075: Aerospace grade, super strong, but poor corrosion resistance.
