This comprehensive guide provides everything you need to know about buying magnesium metal powder in India, from technical specifications to supplier evaluation, with expert insights from Pentaphos.com, a premier manufacturer and supplier.
What is Magnesium Metal Powder? Beyond Basic Dust
Magnesium powder isn’t merely “ground-up metal.” It’s an engineered material with carefully controlled characteristics that determine its performance in specific applications. Unlike granules, powder offers maximum surface area, resulting in faster reaction rates and more complete combustion—properties essential for many advanced applications.
Critical Powder Characteristics:
- Particle Size Distribution: The most important parameter, measured in microns or mesh size
- Particle Morphology: Spherical, irregular, or flake shapes behave differently
- Purity Level: Typically 99.0% to 99.9% for different applications
- Surface Condition: Passive oxide layer thickness affects reactivity
- Apparent Density: Impacts handling and volumetric dosing
Manufacturing Processes: How Premium Powder is Made
At Pentaphos, we employ multiple advanced techniques to produce powder with precise characteristics:
1. Atomization Process (For Spherical Powder)
- Molten magnesium is forced through a nozzle
- High-pressure gas (argon or nitrogen) disintegrates the stream into fine droplets
- Droplets solidify into spherical particles during free fall
- Produces: High-purity, spherical powder ideal for additive manufacturing and metallurgy
2. Mechanical Milling (For Irregular/Flake Powder)
- Pure magnesium chips or turnings are processed in controlled atmosphere mills
- Impact, attrition, or shearing forces reduce particle size
- Produces: Irregular-shaped powder with high surface area for pyrotechnics and chemical applications
3. Electrolytic Process (Ultra-High Purity)
- Specialized process for laboratory and electronics grade powder
- Produces: 99.99%+ purity for critical applications

Frequently Asked Questions (FAQ)
Q1: What is the difference between magnesium powder and magnesium grit/dust?
A: Powder refers to material intentionally manufactured to specific size ranges. Grit or dust is often a byproduct of machining and has uncontrolled size distribution and possible contamination.
Q2: Can we import magnesium powder, or is it better to buy domestically?
A: While import is possible, it involves complex hazardous material logistics, import duties, and long lead times. Domestic suppliers like Pentaphos offer better support, faster delivery, and understanding of local regulations.
Q3: What is the shelf life of magnesium powder?
A: When stored properly in sealed, moisture-proof containers under inert gas, our powder maintains specifications for 12-18 months. Fine and ultra-fine grades have shorter optimal shelf life (8-12 months).
Q4: Do you offer custom particle size distributions?
A: Yes, we can produce powder to your specific size distribution requirements (within safety limits) with minimum order quantities. This is common for specialized applications.
Q5: How is magnesium powder shipped within India?
A: We ship via road transport using DGTA-certified carriers. Packaging meets UN specifications. We handle all necessary documentation and comply with the Explosives Act and Hazardous Material transportation rules.
Q6: Can you supply powder for defense applications?
A: Yes, we are an approved supplier to several defense units and follow all necessary security protocols, documentation, and quality standards required for defense applications.
Q7: What is the minimum order quantity for experimental/research purposes?
A: We offer research quantities starting from 1 kg for genuine R&D institutions, with proper documentation of intended use.
Q8: How do I know if I need spherical vs. irregular powder?
A: Spherical powder flows better and packs more densely—ideal for additive manufacturing and filling molds. Irregular powder has higher surface area—better for chemical reactions and pyrotechnics. Our technical team can guide you.
Q9: What certifications does Pentaphos hold for powder manufacturing?
A: We are ISO 9001:2015 certified, comply with ISO 80079-34 for explosive atmosphere equipment, and follow guidelines of the Petroleum and Explosives Safety Organization (PESO) for applicable products.
