Ceramic shot peening beads service life 20 times longer than glass beads
Shot peening is a cold working process used to produce a compressive residual stress layer and modify mechanical properties of metals and composites, enhancing the fatigue resistance of mechanical parts made of metallic alloys such as hard steel, titanium and aluminum, also to shape and straighten slim hard alloys for aerospace structural components.
In the shot peening process, the surface is hammered with small round shot media (steel shot, glass beads and ceramic beads).
Ceramic beads are zirconia based shot peening media, manufactured by electro-fusion at high temperatures, are high wear and fracture-resistant.
Ceramic beads are available in a shot-peening grade and a surface finishing grade.

Special sizes available against clients’ requirement.
• High consistency from bead to bead leading uniform finishes to the tightest tolerances.
• Precision hardening of the part to increase strength and wear and fatigue resistance.
• High toughness, High durability, Long working life in shot peening
• Smooth spherical surface, low abrasion loss, can reduce wear and tear on peening machines.
- Used for surface strengthening treatment of precision casting parts such as aircraft turbine blades and shafts, ordnance, and various spring gear hydraulic parts to eliminate internal stress.
- Used in the automotive industry for strengthening treatment to the surface of Shock absorber spring to improve its anti-fatigue performance
- Shot peening of gears, machined tools and other metal /alloy parts to eliminate stress and increase surface strength
