Magnalium (MgAl) [45µm]

Magnalium Powder – 45 µm
Chemical Composition: Magnesium (Mg) + Aluminum (Al) alloy
Typical Ratio: 50:50 or 60:40 (customizable)
Particle Size: ~45 µm average
Appearance: Fine grey metallic powder
CAS Numbers:

• Magnesium: 7439-95-4

• Aluminum: 7429-90-5

Description:
Magnalium is a metallic alloy of magnesium and aluminum, prized for its lightweight, high-reactivity, and spark-producing properties. The 45 µm grade is a fine, free-flowing powder that strikes a balance between burn rate and safety, making it ideal for energetic formulations where controlled ignition and powerful reactions are required.

Applications:

Pyrotechnics & Fireworks

• Commonly used in flash powders, strobe compositions, and whistle mixes

• Produces intense white flashes, brilliant sparks, or metallic flame effects

• Safer and more stable than pure magnesium, with reduced moisture sensitivity

• Essential for ignition compositions, delay charges, and fuse coatings

Propellants & Model Rocketry

• Used in composite propellant formulations to increase burn rate and energy output

• Contributes to bright exhaust or flame-enhancing effects

Chemical Reactivity

• Can be used as a reducing agent or component in thermite-style reactions

• Involved in heat-releasing blends or specialty metallurgical processes

Key Properties:

• Density: ~2.0–2.4 g/cm³

• Particle Shape: Irregular flakes/grains (depending on production)

• Reactivity: High, but more stable than pure Mg

• Burns at ~1,200–1,500 °C depending on oxidizer

• Water-reactive; emits hydrogen gas

Handling & Safety:

• Flammable solid – store in a cool, dry, and sealed container

• Avoid contact with moisture, oxidizers, and open flame

• Use non-sparking tools and handle in inert atmosphere for bulk processing

• Wear appropriate gloves, mask, and eye protection

Packaging Options:
Available in 250 g, 500 g, 1 kg, and 5 kg anti-static sealed bags or jars. Bulk pricing on request.
