Frequently asked questions

How do you calculate the weight of copper round bar?

Multiply the cross-section area in square inches by the length in inches and by the density, 0.323 lb per cubic inch for copper (110). For this shape the area is: area = pi / 4 x d squared. A foot of stock is 12 inches, so weight per foot is area x 12 x 0.323.

How does copper compare with steel by weight?

Copper is 14% heavier than carbon steel for the same size: 0.323 lb per cubic inch against 0.2836. The same bar or plate in copper weighs 1.14 times the steel figure.
