Colloidal Silica Grades for Aluminum Alloy Polishing Slurry
Aluminum alloy polishing slurry uses controlled silica particles with application-specific liquid chemistry to balance material removal, surface roughness, brightness and defect control. Grade selection must reflect the alloy series, temper, initial surface, polishing stage, pad and machine conditions.
| Model | Particle Size | SiO₂ Content | Na₂O Content | pH | Shelf Life |
|---|---|---|---|---|---|
| LS30 | 30–40 nm | 30–50% | ≤0.4% | 9.5–10.5 | ≥12 months |
| LS50 | 50–60 nm | 30–50% | ≤0.4% | 9.5–10.5 | ≥12 months |
| LS80 | 80–90 nm | 30–50% | ≤0.4% | 9.5–10.5 | ≥12 months |
| LS100 | 100–110 nm | 30–50% | ≤0.4% | 9.5–10.5 | ≥12 months |
| LS120 | 110–120 nm | 30–50% | ≤0.4% | 9.5–10.5 | ≥12 months |
| LS150 | 140–160 nm | 30–50% | ≤0.4% | 9.5–10.5 | ≥12 months |
| LS180 | 170–190 nm | 30–50% | ≤0.4% | 9.5–10.5 | ≥12 months |
The LS grades are abrasive candidates for aluminum-alloy polishing slurry development, not universal finished compounds. Confirm particle distribution, oversized particles, pH, corrosion behavior and polishing performance on the actual alloy.
Match Particle Size to Removal and Surface-Finish Targets
LS30 and LS50
Finer LS options for final-polishing trials prioritizing low roughness and reduced scratch risk under compatible chemistry.
LS80, LS100 and LS120
Intermediate particle ranges for balancing aluminum removal, surface roughness, brightness and defect control.
LS150 and LS180
Larger candidates for stock-removal trials, subject to strict control of scratches, embedded particles and surface defects.
pH 3–11
The pH can be reviewed after alloy compatibility, corrosion risk, target value and tolerance are defined.
Information Needed for Aluminum Alloy Polishing
Connect the abrasive specification with the alloy, polishing stage, equipment and required surface quality.
- Aluminum substrate: identify alloy series and temper, dimensions, initial roughness, coating or anodized condition.
- Polishing stage: specify stock removal, intermediate polishing, final polishing or another process step.
- Particle specification: provide nominal size, distribution, oversized-particle limit, agglomerate limit and test method.
- Slurry chemistry: state SiO₂ content, target pH, additives, dilution water and permitted sodium level.
- Performance targets: define removal rate, roughness, flatness, gloss or brightness, scratches, pits and corrosion limits.
- Order details: include equipment, pad, trial quantity, annual demand, packaging and destination country.

Packaging Options
Available polyethylene packaging sizes are 25 kg, 250 kg and 1000 kg.
Storage Temperature
Store at 0–40°C and protect from freezing. Temperatures below 0°C can cause irreversible gelation.
Direct Sunlight
Avoid prolonged exposure to direct sunlight during storage and transportation.
Container Closure
Keep containers closed to limit water evaporation and precipitation of solid silica particles.
Aluminum Alloy Polishing Slurry Questions
Which colloidal silica grades can be evaluated for aluminum alloy polishing slurry?
The standard grades are LS30, LS50, LS80, LS100, LS120, LS150 and LS180.
What particle-size range is available for polishing trials?
The published grade ranges start at 30–40 nm and extend to 170–190 nm.

Aluminum Alloy Polishing Slurry Applications
LS grades can be evaluated as abrasive candidates for aluminum alloy polishing. Qualification requires alloy-specific tests for removal rate, roughness, brightness, scratches, pits, corrosion and slurry stability.
Machined Aluminum Parts
Evaluated for precision-finished machined parts after particle distribution, pH, removal and corrosion behavior are qualified.
Automotive Aluminum Components
Candidate slurries can be tested for decorative or functional aluminum components with defined finish and defect targets.
Aerospace Aluminum Components
Can be assessed for compatible precision components after alloy, dimensional and surface-integrity requirements are defined.
Aluminum Mold Surfaces
Can be evaluated for molds requiring controlled roughness, gloss and resistance to scratches or pits.
Pre-Anodizing Surface Preparation
Selected particle ranges may be tested for surface preparation before anodizing, subject to downstream compatibility.
Custom Aluminum Slurries
Supports development around a defined alloy, LS grade, oversized-particle limit, additives and controlled pH.
