ER120 - The original ceramic bead
RIMAX - A dependable milling solution
Rimax is a durable zirconium silicate bead recognized as the standard in many milling processes. It is recommended when large bead sizes are required or in aggressive environments such as in basket mills. Rimax is the product of choice in most traditional applications.
RIMAX also exists in a higher density version, RIMAX HD, with improved wear performance and durability in severe conditions.

ER120 - Zirconia and Silica Composite Material
Manufactured by the fusion of oxides, ER120 combines the benefits of ceramic zirconia and glass. When cooling to room temperature, the melt solidifies with a specific composite material structure made of a zirconia monoclinic phase dispersed in a glassy silica phase.
