Product Description
Brass Cups, also known as cups, are the most critical semi-finished component in the ammunition production chain. They are created through a precise deep drawing process from brass discs, combining technical control and raw material quality to form a key intermediate shape: the cylindrical brass cup that becomes either a cartridge case or a bullet jacket.
Premium Plus manufactures cups from certified CuZn30 and CuZn10 brass, with strict attention to uniform wall thickness, surface smoothness, and dimensional accuracy. Each series is tailored to exact military and industrial calibers, with full traceability of material origin and quality.
Available types:
Case Cup – base for cartridge case production
Bullet Cup – base for forming the metal jacket of the projectile
