Magnesium Metal Powder is a highly reactive, silvery-white metal powder produced via mechanical milling or inert-gas atomization. Engineered for industrial applications requiring rapid reduction, high-energy pyrotechnics, or precise alloying, our powder maintains strict control over active magnesium content and particle morphology to ensure predictable reaction rates in synthesis and metallurgy.
Key Features
High Chemical Reactivity: High active magnesium purity accelerates reduction and synthesis processes.
Controlled Particle Morphology: Available in spherical (gas-atomized) and irregular (mechanically milled) shapes to match specific fluidity and surface-area requirements.
Low Moisture & Oxide Content: Processed and packaged under strict inert atmosphere controls to minimize surface passivation.
Trace Impurity Control: Strict raw material selection keeps iron, copper, and nickel levels minimal to prevent side reactions.

Applications
Chemical Synthesis
Used as a reducing agent in Grignard reaction setups for pharmaceutical and fine chemical manufacturing.
Metallurgy
Acts as a desulfurizing agent in iron and steel production, and as an additive in high-strength aluminum alloy casting.
Pyrotechnics & Defense
Utilized in flare formulations, tracer ammunition, and incendiary compositions requiring high combustion temperature.
Quality Control & Manufacturing Capabilities
Production Assets: Equipped with automated inert-gas atomization lines and sealed ball-milling systems operating under strict argon purge to prevent oxidation.
Particle Analysis: Laser diffraction particle size analyzers (ISO 13320 compliant) verify particle size distribution (D10, D50, D90) for every production lot.
Traceability: Each batch is stamped with a unique lot number linking raw material ingot purity logs, milling logs, and final lab test results.
Certifications: Produced under ISO 9001:2015 quality management systems.

FAQ
Q: How is moisture controlled during storage and transit?
A: Drums are hermetically sealed under argon gas or dry air conditions with tamper-evident seals and inner PE liners tied securely to prevent atmospheric moisture ingress.
Q: Can you supply atomized spherical powder instead of milled irregular powder?
A: Yes. Specify your preferred morphology (gas-atomized spherical or mechanically milled irregular) during inquiry to match your flowability requirements.
Q: What is the shelf life under recommended storage?
A: 6 months from the manufacturing date if stored in a cool, dry, well-ventilated, fire-rated chemical warehouse away from moisture and acids.
