Standard Copper Density Table
| Material | Density |
|---|---|
| Pure Copper | 8.96 g/cm³ |
| Electrolytic Copper | 8.93 g/cm³ |
| Copper Alloy | 8.50 – 8.90 g/cm³ |
| Brass | 8.40 – 8.73 g/cm³ |
| Bronze | 8.70 – 8.90 g/cm³ |
How to Calculate Copper Round Bar Weight
Copper round bars are commonly used in electrical and machining industries.
Formula
Weight = (π ÷ 4) × Diameter² × Length × Density
Example
Suppose:
- Diameter = 50 mm
- Length = 2000 mm
- Density = 8.96
Calculation
Weight = (3.1416 ÷ 4) × 50² × 2000 × 8.96 ÷ 1000000
Result
≈ 35.19 KG
How to Calculate Copper Sheet Weight
Copper sheets and plates are widely used in fabrication and electrical panels.
Formula
Weight = Length × Width × Thickness × Density
Example
- Length = 2000 mm
- Width = 1000 mm
- Thickness = 5 mm
Calculation
Weight = 2000 × 1000 × 5 × 8.96 ÷ 1000000
Result
≈ 89.60 KG
How to Calculate Copper Pipe Weight
Copper pipes are commonly used in HVAC and plumbing industries.
Formula
Weight = π × (OD − Thickness) × Thickness × Length × Density
Example
- OD = 40 mm
- Thickness = 2 mm
- Length = 3000 mm
Calculation
Weight = 3.1416 × (40 − 2) × 2 × 3000 × 8.96 ÷ 1000000
Result
≈ 6.41 KG
How to Calculate Copper Flat Bar Weight
Copper flat bars are used in switchgear panels and electrical busbars.
Formula
Weight = Length × Width × Thickness × Density
Example
- Length = 1000 mm
- Width = 50 mm
- Thickness = 10 mm
Calculation
Weight = 1000 × 50 × 10 × 8.96 ÷ 1000000
Result
≈ 4.48 KG
How to Calculate Copper Busbar Weight
Copper busbars are widely used in electrical distribution systems.
Formula
Weight = Length × Width × Thickness × Density
Example
- Length = 1500 mm
- Width = 100 mm
- Thickness = 12 mm
Result
≈ 16.12 KG
