  1. Copper sheet single sheet (with/foil/row) theoretical weight (kg) 厚度 thickness (mm) * width (m) * length (m) * 8.9

  Brass series single sheet (with/foil/row) material Theoretical weight (kg) 厚度 Thickness (mm) * Width (m) * Length (m) * 8.6

  2. The theoretical weight per metre of copper series bar products (kg) ≈ diameter (mm) * diameter (mm) * 0.007

  Brass Series Bar Product Theoretical Weight per Meter (kg) ≈ Diameter (mm)* Diameter (mm)*0.0067

  Hexagonal Copper Series Bar Product Theoretical Weight per Kilogram (kg) ≈ Distance to Side (mm)* Distance to Side (mm)*0.008

  Hexagonal Brass Series Bar Product Theoretical Weight per Meter (kg) ≈ Distance to Side (mm) * Distance to Side (mm) * 0.0074

  3. Theoretical weight per metre of copper series pipe products (kg) ≈ (outer diameter - wall thickness) (mm) * wall thickness (mm) * 0.028

  Brass series pipe product theoretical weight per meter (kg) ≈ (outer diameter - wall thickness) (mm) * wall thickness (mm) * 0.027
