Verified technical lots directly dispatched from our manufacturing facilities. Explore primary stock specifications ready for containerized international freight.
Understanding the engineering boundaries between mechanical chipping, rasping, and inert gas atomization across demanding industrial sectors.
Manufactured via closed-loop inert gas (Ar/He) atomization under negative pressure. Characterized by high sphericity (≥ 92%), superior flowability (Hall Flow ≤ 28 s/50g), and controlled tap density. Ideal for Laser Powder Bed Fusion (LPBF), thermal spraying, and high-performance metallic matrix composites.
Produced using computer-controlled cold milling and rasping of refined magnesium ingots (≥ 99.9% Mg). Yields irregular, angular morphology offering maximum specific surface area. The premier choice for hot metal desulfurization in steelmaking, pyrotechnic ignition rates, and Grignard reagent synthesis in organic chemistry.
Specialized powders encapsulated with fluoropolymer thin films, organosilanes, or mineral oils (0.5%–2.0%). This structural passivation suppresses natural hydrolytic hydrogen release (H2 evolution suppression > 98%), extending storage shelf-life in humid sea freight environments without sacrificing stoichiometric reaction energetics.

Leveraging China's world-leading raw dolomite and Pidgeon-process primary magnesium clusters to yield uncompromised supply continuity, tight pricing structures, and verifiable batch integrity.
Our direct partnerships across Shaanxi and Shanxi primary reduction hubs guarantee access to virgin 99.9% magnesium ingots. This insulates our factory partners from global commodity spot price shocks and gives wholesale buyers predictable quarterly contract pricing.
Milling and atomization cells operate continuously under certified dry nitrogen or argon blankets with real-time oxygen sensors maintaining O2 levels < 100 ppm. This prevents pre-oxidation skin defects, ensuring elevated active metallic magnesium assays upon site arrival.
Multi-deck ultra-fine ultrasonic sieving and cyclonic air classification allow custom-tailored particle distributions: narrow Gauss cuts, tailored D10/D50/D90 targets, and strict elimination of ultra-fine dust fractions below 10 μm for optimized worker safety handling.
Every single manufactured production lot is backed by rigorous wet titration, Inductively Coupled Plasma (ICP-OES) analysis for metallic trace elements (Fe, Si, Cu, Ni, Cl), and Laser Diffraction (Malvern Mastersizer) to verify PSD compliance prior to shipping container stuffing.
Magnesium powder reacts with moisture to emit flammable hydrogen gas. We engineer every link of our packaging and logistical chain to align with IMDG, ICAO, and localized port handling mandates.
Supplied in heavy-duty UN-approved 1A2 steel drums (50kg, 100kg, or 200kg) fitted with hermetic silicone gaskets and locking levers. Internal dual-layer anti-static polyethylene heat-sealed liner bags flushed with inert argon protect against vapor infiltration.
Full regulatory dossiers supplied for every ocean booking: GHS-compliant multilingual SDS, DGD (Dangerous Goods Declaration), authentic Factory Batch Certificate of Analysis (COA), and third-party inspection reports (e.g., SGS, CIQ) assessing self-heating properties under UN Manual test criteria.
Extensive experience clearing hazardous cargo across North American (EPA/DOT), European (EU REACH registration for metallic magnesium), and Asian gateways. Port-to-door deliveries managed strictly via licensed DG carrier alliances with temperature and moisture telematics tracking.
From metallurgical reaction kinetics to advanced electrochemical storage, magnesium powder acts as a pivotal functional agent across advanced industries.
Injected via co-injection lances with lime/calcium carbide into molten blast furnace iron. Magnesium possesses superior affinity for sulfur at 1350°C, generating insoluble MgS that floats into the slag layer, achieving ultra-low sulfur levels ([S] < 0.001%) in high-tensile steels.
Spherical Mg and Mg-rare earth powders (WE43, AZ91) enable the production of ultra-lightweight structural lattices (density ~1.74 g/cm³), achieving up to a 33% mass reduction over standard aluminum alloys in aerospace housings and satellite brackets.
Emerging as a leading clean energy substrate. High-purity magnesium powder reversibly stores hydrogen as magnesium hydride (MgH2) with exceptional theoretical storage capacity of 7.6 wt.% H2, opening low-pressure, solid-state green transport pathways.
Critical precursor for Grignard reagents (R-Mg-X) required in active pharmaceutical ingredient (API) synthesis, high-performance flares, energetic pyrotechnic formulations, and military countermeasures requiring high burn-rate actinic light emissions.
