Specification-driven supply featuring verified physical parameters, laser granulometry reports, and export compliance.
Understanding manufacturing kinetics, morphology differentiation, and metallurgical purity controls.
Utilizes ultra-high-pressure nitrogen or argon gas streams to atomize a superheated liquid lead stream. Yields highly spherical powder particles with minimal satellite formations, superior Hall flow rates, maximum packing density, and an exceptionally low specific surface area that minimizes surface oxidation.
Optimized for granular, tear-drop, and semi-spherical particle structures. This mechanical technique provides tailored apparent densities suited for sintered friction elements, chemical pyrotechnic initiators, and heavy-density ballast compounding where controlled packing friction is required.
Engineered for high-surface-area spongy powders and ultrafine sub-micron lead particulate. Often implemented for electrochemical batteries, active mass additives, and organic synthesis intermediates requiring accelerated surface reaction kinetics under inert nitrogen stabilization.

Discounts are automatically triggered at 5 MT, 20 MT (Full Container Load - FCL), and multi-container annual supply frameworks. Long-term hedging agreements (3–12 months) are available to protect purchasers against LME volatility.
Narrow cuts (e.g., D10 > 20µm and D90 < 45µm) involve specialized sonic classifying techniques that influence the yield curve. We quote fully factored yields so pricing is predictable from pilot trials to full-scale operations.
Because reactive surface oxides increase at finer mesh thresholds, our fine-powder tiers include vacuum-aluminum foil inner bags with high-purity nitrogen backfill to guarantee chemical stability throughout transoceanic transit.
The strategic benefits of raw smelter proximity, massive industrial infrastructure, and technical economies of scale.
Our manufacturing centers are situated directly adjacent to top primary lead smelting hubs in Henan and Hunan provinces. Direct molten ingot delivery cuts remelt energy consumption and guarantees uninterrupted base metal feedstock availability.
Equipped with closed-loop supersonic gas atomization towers, vacuum induction melting furnaces, and multi-deck electromagnetic air-swept classifiers. Our plants produce tightly controlled particle distributions that eliminate manual re-blending.
By leveraging domestic energy pipelines, highly automated continuous production lines, and high-volume local consumables, our conversion costs per metric ton run 28% to 42% lower than traditional North American or European powder mills.
Direct bonded warehousing and intermodal freight routes connect inland production hubs directly to Ningbo, Qingdao, and Shanghai deepwater ports, ensuring prompt DG maritime container dispatch with zero regional transshipment delays.
From medical radiation shielding to heavy friction composites, discover how precise material specifications drive end-product performance.
Spherical 325-mesh and 400-mesh lead powders are compound-blended into vinyl polymers, natural rubbers, polyurethane, and epoxies to produce flexible radiation shielding garments, mobile X-ray curtains, CT scanner collimator linings, and nuclear isotope storage containers.
Used as an intrinsic solid lubricant phase in metallic and semi-metallic friction composites for high-speed train braking pads, industrial mining winches, and aerospace gearboxes. The fine lead particles shear under intense frictional thermal spikes, preventing catastrophic brake rotor galling.
Next-generation ultra-lead-carbon batteries utilize high-purity ultrafine lead powder combined with capacitive carbonaceous active masses. This drastically suppresses negative plate sulfation during high-rate partial-state-of-charge (HRPSoC) micro-hybrid cycles.
High surface area irregular lead powder acts as a selective reducing agent in fine chemical synthesis, pharmaceutical intermediate preparation, and organometallic reaction steps, where steady metal dissolution kinetics are essential for yield selectivity.
Specialized micronized lead powders are formulated into energetic delay compositions and percussion primers. Controlled particle size distribution ensures a constant, reproducible burn velocity and highly predictable heat transfer characteristics.
Spherical Pb-Sn, Pb-Sb, and Pb-In powders are engineered for high-temperature semiconductor packaging and military-grade electronic assemblies, offering resilience against thermal fatigue cracking under harsh cyclic environments.
International certification, REACH compliance, UN-approved packaging, and documented cold-chain / dry-chain container transport.
We provide full REACH dossier data for European consignments, assisting clients with Authorized Representative (OR) coverage. For specialized industries enjoying RoHS exemptions (aerospace, high-reliability defense, radiation shielding), we supply formal exemption declarations and certified metallurgical origin certificates.
Lead powder consignments are packaged in strict compliance with UN Model Regulations (Class 9 UN 3077 environmentally hazardous substances or Class 6.1 toxic powders depending on particle mesh). We utilize UN-certified steel drums (1A2/Y1.5/...) with heavy-duty locking rings, multi-layer polyethylene inner liners, and desiccants.
