Product Description
The Brass Disc, also known as a brass rondelle, plays a key role in the production of ammunition components and industrial metallurgy. These precision-stamped discs are made from high-grade brass strips and designed as an optimal base for further transformation – primarily deep drawing into brass cups.
Premium Plus manufactures discs with tight dimensional tolerances, ensuring consistent thickness, clean edges, and ideal preparation for downstream mechanical processing. Discs are supplied in packaging suitable for industrial use, ready for immediate integration into automated or manual workflows.

Application and usage
Production of cups for cartridge cases and bullets
Brass discs are directly used as the base material for deep drawing into case cups and bullet cups. Their precise dimensions and clean edges make them ideal for forming components that demand structural integrity and uniformity.
Use in military and civilian defense manufacturing
Brass discs are widely used in both government defense programs and private-sector ammunition factories. They meet the strict standards required for high-volume and high-reliability applications in various calibers and configurations.
Core component for forming Cartridge Cases and Bullet Cups
As an essential transitional product between strip and cup, the disc enables the accurate transformation into finished components without compromising mechanical properties during drawing, annealing, or trimming.
Base material for further mechanical and thermal processing
Engineered for compatibility with forming, heat treatment, and finishing workflows, brass discs are ideal for integration into automated production lines and advanced manufacturing systems.
