Alpha Brasses
Based on their crystalline structures, some brasses are categorized as alpha brasses, in which majority is copper and the zinc content is about 37% or less. UNS C26000, aka cartridge brass, is a well-known example of this variety of alloy, and it is very ductile, malleable, and ideal for cold working. Other low zinc brasses are 70/30 brass and yellow brass, which are often used for hardware and ornamental projects.
