Frequently asked questions
How do you calculate the weight of bronze round bar?
Multiply the cross-section area in square inches by the length in inches and by the density, 0.322 lb per cubic inch for bronze (932 bearing bronze). 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 0.322.
How does bronze compare with steel by weight?
Bronze is 14% heavier than carbon steel for the same size: 0.322 lb per cubic inch against 0.2836. The same bar or plate in bronze weighs 1.14 times the steel figure.
