Choosing the right type of aluminum powder is crucial in various industrial applications. This news article, based on actual manufacturing standards and industry experience, explains the differences between different types of aluminum powder, their key parameters, and practical selection steps.
Aluminium powder—also written as aluminum powder—is produced by atomizing molten aluminium into fine particles. It is widely used in coatings, AAC blocks, fireworks, metallurgy, 3D printing, and chemical reactions.
Its performance depends on:
Particle size
Particle shape (spherical, irregular, flake)
Surface coating (e.g., SiO₂-coated)
Reactivity & purity
Leafing vs. non-leafing behavior
Industry reports (Grand View Research 2024) show increasing demand driven by construction, additive manufacturing, and advanced coatings.
SiO₂ coated aluminium powder utilizes a silicate coating process to significantly enhance oxidation resistance and storage stability. This product is particularly suitable for industries requiring safer handling and extended shelf life.
Key advantages:
High anti-oxidation performance
Stable during transportation
Suitable for water-based or high-humidity environments
Common uses:
Chemical reactions
Pigment production
Safety-focused coatings
Leafing aluminium powder forms a reflective metallic layer on the surface of a coating. This effect is achieved by treating aluminium flakes with hydrophobic additives.
You should choose leafing aluminium powder if you need:
High metallic brightness
Mirror-like decorative effects
Surface reflectivity
Applications include:
Metallic paints
Marine reflective coatings
Protective finishes
Aluminium powder for AAC reacts with lime and water to produce hydrogen gas, forming tiny bubbles inside concrete blocks.
Why AAC manufacturers rely on this material:
Consistent bubble formation
Stable expansion rate
High purity and controlled reaction speed
Check particle fineness (affects gas release rate)
Confirm purity level (reduces impurities and improves block strength)
Verify reactivity test data from the supplier
Silver Rocket provides AAC-grade powders with optimized reaction profiles for efficient and uniform aeration.
Spherical aluminium powder is produced through gas atomization. Its round shape gives excellent flowability and packing density.
Best used for:
3D printing metal powders
Powder metallurgy
Conductive materials
Thermal sprays
Advantages:
High electrical/thermal conductivity
Low impurity level
Uniform flow in automated systems
To help you select the right material, here is a quick comparison based on industrial needs:
| Type of Aluminium Powder | Shape / Structure | Best for | Key Benefits |
|---|---|---|---|
| SiO₂ coated aluminium powder | Irregular | Chemicals, water-based coatings | Oxidation resistance |
| Leafing aluminium powder | Flake (treated) | Decorative coatings | High gloss & leafing effect |
| Aluminium powder for AAC | Fine powder | AAC blocks | Controlled gas release |
| Spherical aluminium powder | Round | 3D printing, metallurgy | Flowability & density |
Pigment powder is flake-shaped for metallic effects; standard aluminium powder is mostly spherical or irregular for reactions or structural use.
Yes. Silver Rocket offers custom particle sizes, coatings, reactivity levels, and packaging options for industrial users.
Identify your application → select particle shape → confirm purity → request supplier test reports.
It must be stored in cool, dry environments. SiO₂ coated versions improve safety and shelf stability.
Selecting the correct aluminium powder—whether aluminum pigment powder, leafing aluminium powder, SiO₂ coated aluminium powder, or spherical aluminium powder—is essential for achieving consistent performance and safety in your production process. Understanding particle shape, purity, and application requirements ensures you get the best results.
