Aluminium Powder [Atomized, 45µm]

Aluminium Powder – Atomized, 45 µm
Type: Spherical atomized aluminum powder
CAS Number: 7429-90-5
Average Particle Size: ~45 µm
Purity: ≥99% Al
Appearance: Fine grey metallic powder

Description:
This atomized aluminum powder consists of finely dispersed, spherical particles with an average size of ~45 µm. Produced via gas atomization, the powder offers excellent flowability, uniform particle distribution, and high chemical reactivity, making it ideal for a range of industrial, metallurgical, and pyrotechnic applications.

Applications:

Metallurgy & Additive Manufacturing

• Used in metal injection molding (MIM) and powder metallurgy processes

• Suitable for aluminum-based alloys, sintering, and thermal spraying

• Serves as a base material for powder coating or metallic pigment production

Pyrotechnics & Propellants

• Acts as a high-energy fuel in flash powders, rocket fuels, and thermite compositions

• Offers controlled burn rates and bright combustion when paired with oxidizers

• Used in delay charges, igniters, and metal-based smoke formulations

Chemical Industry

• Serves as a reducing agent and reactive metal for lab-scale synthesis

• Involved in exothermic welding, reactive metal blends, and heat-releasing systems

Key Properties:

• Particle Shape: Spherical

• Surface Area: Moderate (~0.5–1.5 m²/g)

• Reactivity: Medium–high

• Flowability: Excellent for blending and mechanical dosing

• Insoluble in water; reacts with acids and alkalis

Handling & Safety:

• Highly flammable in powder form — avoid open flame, sparks, or static

• Store in a cool, dry, and inert atmosphere (e.g., argon or nitrogen for bulk)

• Use appropriate grounding, anti-static tools, and PPE when handling

• Avoid inhalation of fine dust

Packaging Sizes:
Available in 100 g, 500 g, 1 kg, and 5 kg anti-static, sealed containers. Bulk on request.
