C26000 Cartridge Brass, also known as 70 30, is copper alloyed with zinc. C260 Cartridge Brass has a warm yellow tone and is most commonly found in tube, sheet and plate form. C260 is commonly called Cartridge Brass because it has traditionally been for ammunition cartridges and shells. 70 30 brass has a wide range of uses, including applications in architectural, electrical, consumer, construction and plumbing industries. Cartridge Brass, also known as Spinning Brass, is capable of undergoing severe forming and drawing
