Introduction
Seraj Aluminum Powder is a 99 %-pure, finely milled metal powder manufactured in Mashhad, Iran. Its controlled particle size and reactivity make it a sought-after gas-forming additive in autoclaved aerated concrete (AAC) as well as a functional pigment and reducing agent across multiple industries. Whether you produce lightweight blocks, specialty coatings, or metallurgical alloys, Seraj delivers consistent expansion performance, bright metallic luster, and dependable supply for export markets.(samarcapital.co, آداک فلز کاوه)
Why Aluminum Powder Matters in AAC Production
When meets the alkaline slurry of cement, lime, and water, it reacts to release hydrogen gas. The bubbles double the mix volume, creating millions of uniform air pores that give AAC blocks their low density, thermal insulation, and sound attenuation.(CHAL)
Key Reaction
2 Al + 3 Ca(OH)₂ + 6 H₂O → 3 CaO·Al₂O₃·6 H₂O + 3 H₂↑
Precise dosing and uniform particle size are critical—too coarse and gas generation lags, too fine and excessive foaming weakens the cake. Seraj’s narrow D50 distribution (15–25 µm) keeps expansion predictable while minimizing waste.(aac-worldwide.com)

Core Applications
1. Autoclaved Aerated Concrete (AAC)
- Uniform cell structure for blocks and panels
- Density range 450 – 600 kg/m³
- Meets IS 2185-3 & EN 771-4 gas-forming requirements
2. Protective & Metallic Coatings
- Flake grades give silver brilliance to anti-corrosion paints and printing inks.
- Improves barrier effect and UV reflectance.
3. Metallurgy & Pyrotechnics
- Serves as a reducing agent in thermic reactions.
- Used in exothermic welding and specialized propellant formulations.
Competitive Advantages
- Local Raw Material, Stable Cost — Proximity to Iranian smelters keeps feedstock secure and pricing competitive.(samarcapital.co)
- High Reactivity, Low Dusting — Controlled atomization and phosphated surface reduce fines and explosion risk during handling.
- Export-Ready Packaging — 25 kg laminated kraft bags or 200 kg UN-certified drums, palletized and shrink-wrapped for sea freight.
- Short Lead Time — 1 billion IRR credit line enables three-month production cycles with 13.5 % projected ROI, ensuring steady output for international buyers.(samarcapital.co)
Handling & Safety
Aluminum powder is classified as a flammable solid (UN 1396). Store in a cool, dry, well-ventilated area away from acids and oxidizers. Always ground transfer equipment to prevent static discharge and consult the product SDS before use.
