What Is Lead? Engineering Overview
Lead (Pb) is a dense, malleable, corrosion-resistant metal widely used in radiation shielding, ballast, roofing, and acoustic applications. With a density of 11.34 g/cm³, it provides exceptional weight-to-volume ratio.
Lead Density Explained
Standard density: 11,340 kg/m³, 706.5 lb/ft³, 11.34 g/cm³. Density determines weight for a given volume. Our calculator uses these references, adjustable for alloys (e.g., lead-antimony).
Weight Calculation Formulas
Rectangular block: Volume = L×W×H; Weight = Volume × Density.
Cylinder: π×r²×L.
Pipe: π×(R² - r²)×L.
Sphere: (4/3)×π×r³.
Sheet: same as block.
Practical Examples
Example: Lead sheet 1m × 1m × 5mm => Vol=0.005 m³ => mass=0.005×11340=56.7 kg => 125 lbs.
