Ceramic Shot Peening Beads, CZ

Type: CZ

Ceramic Shots for Shot Peening



  • Highest Durability - Due to strong mechanical resistance and high toughness

  • Highest consistency from bead to bead in size distribution, sphericity, density and hardness

  • No Metallic Contamination and Lowest Dust Generation

  • Fine Shots efficient for multi peening steps

  • Lowest Machine Wear - Due to reduced shot throwing velocity needed to achieve the same peening intensities, and the extremely smooth beads' surface

  • Improved Part Life - Offering high level residual compressive stress close to the surface


CZ Beads can be used in these applications, just name a few:

  • Shot peening to extend fatigue life by stress relieving, peen-forming and peen-straightening

  • Intensive use in wheel turbine machines and on High Strength Steel (HSS) at the same intensity range as steel shots

CHEMCO is a world-class ceramic beads and balls producer. All our products' formulations contain more or less Zirconia (ZrO2), which is an advanced ceramic material with a title of "Ceramic Steel". This single material offers the traditional ceramics benefits of hardness, wear and corrosion resistance. We can supply various densities (Light, Medium & High) media with the complete range of sizes (0.01 - 70 mm), which suit different fine-grinding (milling & dispersion) as well as impact surface treatment applications. We've been proudly exporting our products from China to more than 45 different countries around the world!

CHEMCO has a depicted R&D department manned by committed scientists and technicians. As a team they constantly strive to explore and innovate the new value of products. The company has also established a complete quality control system and maintained an individual department controlling the products' quality. Equipped with a complete set of modern analysis instruments and always executing higher standard in the industry, our products quality can get effective assurance.

CHEMCO is ISO 9001:2015 certified by QA International
