Industrial Mineral Supply #12 Glass Beads – Extra Fine 140-230 Mesh for Blasting Cabinets (10 LBS)

Industrial Mineral Supply #12 Glass Beads — Extra Fine Blasting Media

Our #12 Glass Beads deliver a balanced blend of cleaning, finishing, and peening performance. Packaged as a 10 lb (4.54 kg) bag, this media is suitable for blast cabinets or handheld sand blasting guns where controlled impact and surface integrity matter. The round beads flow smoothly and offer a bright, consistent finish on metal surfaces.

What you can achieve in practice

• Cleaning and prep: The beads clean and prep metal surfaces without altering tolerances or introducing ferrous pollutants, helping parts stay true to spec.
• Finishing: They help blend machining marks and seal pores, producing a smoother overall appearance that resembles a glass bead peen effect.
• Peening: Glass bead peening can reduce tensile stress in metal parts, potentially contributing to improved fatigue performance under cyclic loading.
• Environmental edge: The media contains no free silica and supports recycling, which can reduce waste when you recycle the beads multiple times.
• Operational efficiency: Optimal cleaning efficiency is achieved with a nozzle angle of roughly 45°–60°, supporting consistent results across parts with varying geometries.

Real-world use cases

Ideal for maintenance and fabrication workflows where small components require a clean, uniform surface prior to coating, plating, or assembly. The glass beads deliver a bright, satin-like finish on bolts, brackets, housings, and other metal parts without introducing harsh abrasives into tolerances.
