Ceramic Shot Peening MediaSaint-Gobain ZirPro Zirshot® is the industrial reference media for ceramic shot peening, enhancing the fatigue resistance of mechanical parts made of metallic alloys such as hard steel, titanium and aluminum. In shot forming, Zirshot also is used to shape and straighten slim hard alloys for aerospace structural components. Zirshot combines the high hardness (700HV) and toughness of ceramic materials with optimal spherical bead shape and tight size distribution, resulting in outstanding peening benefits: High energy transfer at the impact point on the metallic substrate Preservation of the integrity of the peened surface with smooth and uniform surface finishZirshot is available in standard size ranges.
