Frequently Asked Questions: GB-11 Glass Bead Abrasives

1. What is the primary function of GB-11 (53-106 Micron) Glass Beads?

The primary function is impact treatment, specifically used for cleaning, finishing, and light peening. Because the size is strictly controlled between 53 and 106 microns, it provides a consistent satin finish without removing the base metal of the workpiece.

2. Why is “Roundness ≥ 80%” important for industrial blasting?

Roundness ensures that the energy of the impact is distributed evenly. If beads are broken or angular, they “cut” the surface rather than “peening” it. A high roundness percentage ensures the integrity of the substrate and increases the fatigue life of metal parts.

3. Are Glass Beads safer than sand for abrasive blasting?

Yes. Unlike sand, glass beads are made from soda-lime glass which contains no free silica. This significantly reduces the risk of silicosis. They are also chemically inert and do not contaminate the surface being treated.

4. How does the 53-106 Micron range affect the surface profile?

This specific range (often referred to as Grade 11 or Fine) creates a very low surface roughness ($R_a$). It is ideal for medical devices and aerospace components where maintaining strict dimensional tolerances is mandatory.

5. Can GB-11 Glass Beads be recycled?

Yes, glass beads are highly recyclable. Due to their soda-lime composition and spherical shape, they can be reused multiple times in a closed-loop system (like a blast cabinet) before the beads eventually break down into fines.

Glass Bead Abrasive | GB-11 | 53-106 Microns (0.002″–0.004″)

Achieve a superior, uniform finish with our GB-11 Glass Bead Abrasive. Engineered for precision and consistency, this media is the industry standard for applications requiring a smooth, satin appearance without removing base material.

With a controlled size range of 53 to 106 microns and a high roundness rating of ≥ 80%, our GB-11 beads provide a gentle yet effective impact, making them ideal for delicate components and high-tolerance aerospace or medical parts.

Technical Specifications

  • Grade: GB-11

  • Micron Size: 53 – 106 μm

  • Diameter (Inches): 0.002″ – 0.004″

  • Roundness: ≥ 80% (True Spheres)

  • Material: Soda-Lime Glass (Chemically Inert)

  • Appearance: Clear, Odorless, Fine Powder-like Spheres

Key Performance Benefits

  • Non-Aggressive Finishing: Unlike crushed glass or aluminum oxide, these spherical beads clean surfaces without changing dimensional tolerances.

  • Stress Relief (Peening): The high roundness (≥ 80%) ensures even compressive stress across the metal surface, enhancing fatigue strength and preventing stress corrosion cracking.

  • Environmentally Friendly: 100% recyclable, chemically inert, and free of lead or crystalline silica, ensuring a safer workspace.

  • Consistent Surface Profile: The narrow 53-106 micron range delivers a predictable, repeatable satin finish every time.

Common Applications

  • Cleaning: Removing scale, rust, and light carbon deposits from engine parts and molds.

  • Finishing: Creating a decorative, glare-free “satin” finish on stainless steel, aluminum, and brass.

  • Deburring: Removing small burrs from precision-machined components.

  • Pre-Coating Prep: Cleaning surfaces before plating or painting to ensure maximum adhesion.

Compatibility

Our GB-11 Glass Beads are designed for use in:

  • Suction / Induction Blast Cabinets

  • Pressure Blast Systems

  • Wet Blasting Equipment

Pro Tip: When using GB-11, maintain a lower blast pressure (40–60 PSI) to maximize the life of the media and prevent bead shattering, ensuring your finish remains consistent across large batches.
