Frequently asked questions
How do you calculate the weight of brass flat bar?
Multiply the cross-section area in square inches by the length in inches and by the density, 0.307 lb per cubic inch for brass (360). For this shape the area is: area = width x thickness. A foot of stock is 12 inches, so weight per foot is area x 12 x 0.307.
How does brass compare with steel by weight?
Brass is 8% heavier than carbon steel for the same size: 0.307 lb per cubic inch against 0.2836. The same bar or plate in brass weighs 1.08 times the steel figure.
