Type: AYZ
Ceramic Shots for Ultra-Fine Shot Peening
​CHEMCO AYZ high-density yttria-zirconia ceramic shots combine extreme hardness, high density, and exceptional toughness in a fine-particle format. Engineered for both intensive peening and surface finishing, they deliver the highest Almen intensities on metallic substrates while producing an ultra-smooth, satin-like finish.
Features
-
Intensified surface compression – Compared to conventional steel shots, AYZ transfers kinetic energy more efficiently, embedding deeper and more uniform compressive residual stresses right where they matter most.
-
Flawless finishing – The smooth, round morphology ensures gentle yet effective treatment, preserving the geometric integrity of even delicate parts.
-
Signature satin gloss – From consumer electronics to automotive trim and architectural surfaces, AYZ imparts a distinctive matte-sheen finish that elevates visual appeal.
