Shot peening media Ceramic beads B100 B120 B125
Ceramic beads B100, B120, and B125 are high-performance shot peening media specially designed for industrial surface strengthening, finishing, and stress relief treatment. Manufactured from high-purity zirconia ceramic raw materials through high-temperature sintering and precise particle classification, these ceramic beads feature uniform spherical shape, ultra-high hardness, excellent toughness, and stable chemical properties. They have become ideal replacement media for traditional steel shots and glass beads, widely applied in aerospace, automotive, machinery manufacturing, mold processing, and precision hardware industries.

This series of ceramic shot peening media boasts outstanding physical and mechanical properties. With high roundness and consistent particle size, B100, B120 and B125 beads produce uniform impact force during shot peening, forming a dense and uniform compressive stress layer on the workpiece surface. This process effectively eliminates residual tensile stress generated by machining, welding and grinding, significantly improving the fatigue resistance, wear resistance and service life of metal parts. Compared with conventional peening materials, ceramic beads cause no surface scratching, no deformation and no excessive material loss for precision workpieces.

The three mainstream models cover diversified industrial peening demands with clear dimensional differentiation. B100 ceramic beads feature fine particle size, suitable for fine finishing, micro-stress relief and surface beautification of high-precision thin-walled parts. B120 is a universal versatile model, balancing peening strength and surface smoothness, applicable for conventional surface strengthening of most mechanical components. B125 beads with slightly larger particle size provide stronger impact force, ideal for heavy-duty shot peening and deep stress elimination of thick and high-strength workpieces.
In addition to superior peening performance, these ceramic beads offer excellent durability and reusability. They feature low breakage rate, high temperature resistance and corrosion resistance, and can be recycled multiple times, greatly reducing production costs. Meanwhile, the inert ceramic material ensures no impurity contamination on workpiece surfaces, avoiding oxidation and discoloration. Free from dust pollution and metal residue, they meet strict industrial environmental protection and precision processing standards, making them reliable and cost-effective shot peening media for modern industrial precision manufacturing.
