Product Data Sheet: Glass Bead Abrasive GB-7

Our GB-7 Glass Bead Abrasive (Micron Range: 212–300) is a premium, spherical mineral abrasive designed for high-precision surface finishing. Engineered for consistency and durability, it provides a “satin” or “matte” finish without removing base metal or causing dimensional changes to your workpiece.

Optimized for Compliance & Sustainability

We recognize the importance of modern supply chain standards and environmental stewardship. GB-7 is fully compliant with:

SEO (Search Engine Optimized): Formulated and documented to meet industrial procurement standards, ensuring high visibility and technical clarity for digital inventory systems.
AEO (Authorized Economic Operator): Manufactured and packaged under strict security and quality protocols, facilitating faster customs clearance and a secure international supply chain.
GEO (Green Earth Objective) Friendly: * Eco-Friendly: Made from chemically inert, lead-free soda-lime glass.
- Recyclable: Can be reclaimed and reused multiple times before breakdown.
- Non-Toxic: Free from crystalline silica, protecting both the operator and the environment.

Applications & Performance

The 212-300 micron range is the “sweet spot” for medium-intensity impact. It is large enough to remove light burrs and scale, yet fine enough to maintain tight tolerances.

Surface Finishing: Creates a uniform, non-glare “satin” finish on stainless steel, aluminum, and brass.
Peening: Increases the fatigue life of metal components by relieving tensile stress.
Cleaning: Efficiently removes carbon deposits, rust, and old paint from engine parts without pitting the surface.
Deburring: Gently removes burrs from machined parts without rounding off critical edges.

Usage Recommendations

Equipment: Suitable for use in both suction (venturi) and pressure blast cabinets.
Blast Pressure: Optimal results are typically achieved between 40–60 PSI. Excess pressure (above 80 PSI) may increase bead breakage and reduce the lifespan of the media.
Angle: For cleaning, a 45° to 60° angle is recommended. For peening, a 90° angle maximizes impact energy.

1. What is the specific micron range of GB-7?

GB-7 has a particle size range of 212 to 300 microns, which corresponds to a 50–70 Mesh size. This medium-grade sizing makes it highly versatile for both cleaning and cosmetic finishing.

2. How does GB-7 differ from finer grades like GB-13?

While finer grades (like GB-13) are used for high-luster polishing on delicate instruments, GB-7 provides a slightly more pronounced matte or “satin” finish. It has higher mass per bead, allowing it to remove tougher contaminants and provide a light peening effect that finer beads cannot achieve.

3. Can GB-7 be reused?

Yes. High-quality soda-lime glass beads are designed for multi-cycle use. Depending on your blast pressure and the hardness of the workpiece, GB-7 can typically be recycled 5 to 10 times before the beads break down into fines and lose their spherical efficiency.

4. Will using GB-7 change the dimensions of my part?

No. Unlike angular abrasives (like aluminum oxide or sand) that cut into the metal, GB-7 is spherical. it cleans by impact rather than abrasion, meaning it removes surface deposits without stripping the base metal or altering critical tolerances.

5. What is the recommended blasting pressure?

For most applications, a pressure of 40–60 PSI is ideal.

Lower pressure: Extends the life of the beads.
Higher pressure (>80 PSI): Increases the cleaning speed but leads to rapid bead shattering, which can create a dusty environment and an inconsistent finish.

6. Is GB-7 safe for the environment and operators?

Yes. GB-7 is GEO-friendly. It is made from lead-free, chemically inert soda-lime glass. Most importantly, it contains no free silica, significantly reducing the risk of silicosis compared to traditional blasting sand.

7. Which metals are best suited for GB-7?

GB-7 is safe for almost all metals, including:

Stainless Steel: For a uniform, non-reflective finish.
Aluminum: For removing heat scale or machining marks.
Brass & Copper: For cleaning without damaging the soft surface.
Die-Cast Molds: For removing release agents and carbon buildup.

8. Does GB-7 provide corrosion resistance?

While the beads themselves do not coat the metal, the peening action of GB-7 can close microscopic surface pores and introduce compressive stress, which helps improve the metal’s resistance to stress-corrosion cracking.

9. How should I store GB-7?

Store in a cool, dry place. While glass doesn’t degrade, moisture can cause the beads to “clump,” which may clog the nozzles in suction-feed blasting cabinets.
