1. What is an Aluminium Coil Weight Calculator?

Definition: This calculator estimates the weight of an aluminium coil based on its dimensions and material density.

Purpose: It helps manufacturers, engineers, and metal workers determine the weight of aluminium coils for transportation, storage, and material planning.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Weight of the coil (kg)
• \( OD \) — Outer diameter of the coil (meters)
• \( ID \) — Inner diameter (core diameter) of the coil (meters)
• \( Width \) — Width of the coil (meters)
• \( Density \) — Density of aluminium (typically 2700 kg/m³)

Explanation: The formula calculates the cross-sectional area of the coil material and multiplies by width and density to get total weight.

3. Importance of Aluminium Coil Weight Calculation

Details: Accurate weight calculations are crucial for logistics, structural support design, and material cost estimation in manufacturing processes.

4. Using the Calculator

Tips: Enter all dimensions in meters. Default density is set to 2700 kg/m³ (pure aluminium). For alloys, adjust density accordingly.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density of aluminium?
A: Pure aluminium has a density of about 2700 kg/m³, but alloys may range from 2600-2800 kg/m³.

Q2: How do I measure OD and ID accurately?
A: Measure across the widest points of the coil for OD, and measure the core diameter for ID.

Q3: What if my coil has no core (ID = 0)?
A: For solid aluminium (no hole), set ID to 0 in the calculator.

Q4: Does this account for coil imperfections?
A: The calculation assumes perfect geometry. For very precise measurements, consider adding 1-2% for real-world variations.

Q5: Can I use this for other metals?
A: Yes, by changing the density value. For steel use ~7850 kg/m³, for copper use ~8960 kg/m³.
