Superior Peening performance
Peening with Zirshot ceramic shots offers:
- High level of compressive stress near the surface
- Smooth surface finish that minimizes crack initiation
- Very low material abrasion that maintains accuracy of fine geometries
- High rebound that allows homogeneous coverage of intricate geometries
- Very low levels of particle embedment
- No need for decontamination post-treatments for non-ferrous alloys
- Cost savings on the downstream processes (coating, polishing)


Guaranteed quality and versatility
Because quality of the peening media is a critical parameter that directly impacts the service life of treated components, ZirPro manufactures shot peening media using tightly controlled procedures and specifications, enabling Zirshot to conform to the most stringent aerospace and automotive ceramic shot peening standards.
