Aluminum fine powder consists of finely divided aluminum particles, typically metallic and silvery-white in appearance. It is produced by atomization or grinding of bulk aluminum and is valued for its high surface area, excellent conductivity, and lightweight metallic properties. Aluminum fine powder is extensively used in various industrial applications including metallurgy, pyrotechnics, coatings, additive manufacturing, and as a pigment. Due to its reactivity, it requires careful handling and storage. Its fine particulate nature makes it particularly useful where rapid oxidation or reaction is desired, such as in explosives or energetic materials. It is also employed in the manufacturing of paints, inks, and cosmetics to impart metallic luster.

- Container Type: Use airtight, non-reactive containers (e.g., steel drums) with inert atmosphere if possible
- Shelf Life: Stable if stored properly, away from moisture and contaminants
- Special Handling: Minimize dust generation; use grounding and bonding to prevent static discharge; PPE including respirators, gloves, and eye protection required
5. Regulatory & Compliance Attributes
- Regulatory Status: Subject to hazardous material regulations due to flammability and dust explosion risk
- Transportation: Classified as a hazardous material (flammable solid) for shipping
- Waste Disposal: Follow local hazardous waste regulations; avoid releasing dust into environment
6. Environmental & Health Impact
- Ecotoxicity: Low direct ecotoxicity but dust inhalation is hazardous to humans and animals
- Persistence: Does not biodegrade; remains as metallic aluminum in environment
- Carcinogenicity: Not classified as carcinogenic; inhalation of fine dust may cause respiratory irritation
- Biodegradability: Not biodegradable (inorganic metal powder)
- PPE: Use gloves, anti-static clothing, safety goggles, and NIOSH-approved respirators to avoid inhalation and skin contact.
- Dust Control: Employ local exhaust ventilation and dust collection systems to control airborne particles.
- Static Control: Use grounding and bonding procedures to prevent electrostatic sparks.
- Fire Prevention: Keep away from open flames, sparks, and other ignition sources.
- Hygiene: Avoid eating, drinking, or smoking during handling; wash hands thoroughly afterward.
First Aid Measures
- Inhalation: Move person to fresh air immediately; administer oxygen if breathing is difficult; seek medical attention for respiratory distress.
- Skin Contact: Wash skin thoroughly with soap and water; remove contaminated clothing; seek medical advice if irritation develops.
- Eye Contact: Rinse eyes with plenty of water for at least 15 minutes; seek medical care if irritation persists.
- Ingestion: Not expected to be a common route of exposure; rinse mouth and seek medical advice if ingested.
Firefighting Measures
- Fire Hazards: Aluminum powder is highly flammable and explosive in dust form; may ignite spontaneously in air or on contact with water releasing hydrogen gas.
- Extinguishing Media: Use Class D fire extinguishers, dry sand, or specialized metal fire extinguishing powders. Do NOT use water or COâ‚‚ as these may exacerbate the fire.
- Special Precautions: Firefighters must wear full protective gear and self-contained breathing apparatus (SCBA).
Preventive Actions: Avoid dust accumulation; control ignition sources in storage and handling areas.
