Weight of round bar: copper and alloys — theoretical mass table
Theoretical weight for typical sizes in kg/m. Material: Copper and alloys; shape: Round bar. Values are calculated from the grade density in the reference book without rolling tolerances, so the actual weight may differ within the tolerances.
