Application and usage
Stamping of brass discs and rondelles
Brass strip serves as the starting material for precision-stamped discs, known as rondelles, which are later deep-drawn into cups. Its consistent thickness and clean surface ensure minimal waste and high accuracy in stamping processes.
Production of case and bullet cups
High-quality brass strip is essential in forming case and bullet cups through deep drawing. The choice of alloy (CuZn10 or CuZn30) enables optimal mechanical behavior depending on whether the cup is destined to become a bullet jacket or a cartridge case.
Further processing into cartridge cases and projectile components
Once formed into cups, the material undergoes further processing such as annealing, trimming, and forming. Brass strip sets the tone for final component precision by ensuring structural integrity at every step of the transformation chain.
Electromechanical and energy sector applications
Beyond ammunition, brass strip is used in the production of components for electromechanical systems, connectors, terminals, and heat exchangers. Its corrosion resistance and formability make it valuable in energy, electronics, and precision engineering industries.
