Glass bead peening strengthens metal surfaces by inducing compressive stress and improving fatigue resistance in aerospace and automotive parts.
Shot peening with glass beads induces beneficial compressive stress on metal surfaces, reducing the risk of fatigue cracking and extending component life. Unlike aggressive abrasives, spherical glass media peens without removing significant material.
The process is standard in aerospace, automotive, and heavy machinery manufacturing where fatigue failure must be prevented.
How Glass Bead Peening Works
Round beads impact the surface at controlled pressure, creating a uniform dimple pattern. Each impact transfers compressive stress below the surface, counteracting tensile loads during operation.
Glass beads are non-metallic, so they do not embed iron contamination — critical for stainless steel and non-ferrous alloys.
Recommended Media
Fine, 1 mm, and 1.5 mm glass beads are common peening sizes. AF and AQ grades offer high consistency for precision components. Asian Glass Beads supplies media compatible with automated peening machines and manual blast cabinets.
