Explore our core selection of metal powders, specialty alloys, pure industrial gases, and chemical intermediates.
Within the spectrum of sub-micron and micro-fine metal powders, the 1.5 micron aluminum powder occupies a critical technical threshold. Characterized by its extremely high specific surface area, controlled particle size distribution (PSD), and highly reactive surface chemistry, this particular particle grade bridges the gap between nanoscale materials (which suffer from handling risks and rapid spontaneous oxidation) and larger industrial-grade powders (which lack the necessary reactivity and packing density).
Crucial Technical Insight: At 1.5 microns (D50 ≈ 1.5 µm), the active aluminum content (Al) remains exceptionally high (≥ 98.0% to 99.5%), while providing a reaction rate and burning velocity that cannot be matched by standard 10 or 20-micron alternatives. Achieving this requires high-precision inert gas atomization processes controlled under strict thermodynamic environments.
The manufacturing process of YANXA's 1.5 micron aluminum powder utilizes state-of-the-art closed-loop inert gas atomization systems. Molten high-purity aluminum (purity ≥ 99.99%) is fed into an atomizer nozzle where it is shattered by high-velocity jets of pure nitrogen gas (or helium/argon mixtures for specialty runs). Because aluminum in the sub-10 micron range is highly pyrophoric, oxygen levels throughout the entire milling, classifying, and collection cycle are monitored and maintained below 0.1% using online oxygen analyzers.
By controlling the gas-to-liquid ratio, nozzle geometry, and cooling rates, we achieve highly spherical morphology. Spherical particles are highly valued because they provide superior flowability (essential for powder bed 3D printing and precise mixing in polymer metrics) and optimal packaging density when blended with larger matrix grains.
For high-precision applications like aerospace solid propellants, energetic compositions, and solar metallization pastes, the particle size distribution must be strictly unimodal and narrow. Every batch of YANXA 1.5 Micron Aluminum Powder undergoes rigorous Quality Control (QC) screening including laser diffraction particle size analysis (e.g., Malvern Mastersizer 3000), helium pycnometry for density calculation, and scanning electron microscopy (SEM) for morphology verification.
Quantifying our manufacturing capabilities, engineering footprint, and product characteristics.
Uncovering the pivotal roles of micro-fine aluminum powders in advanced modern technologies.
Due to its thermodynamic properties and rapid ignition kinetics, 1.5 micron aluminum powder serves as a high-performance burning rate modifier in solid rocket motors and military explosive compositions, enhancing specific impulse.
In photovoltaic manufacturing, spherical micro-aluminum powders are key components for formulating local back surface field (Al-BSF) contact pastes, reducing resistivity and boosting solar cell conversion efficiency.
Micro-fine spherical particles allow for optimal distribution within print beds, enabling high-density sintering of complex metallic geometries in aerospace, medical, and automotive prototyping.
Yanxatech System Industries Limited (YANXA) has integrated Industry 4.0 principles to address the core challenges of global material procurement: price volatility, quality variance, and supply chain disruptions. In our partner facilities, fully automated feedback loops monitor particle geometry in real time. We utilize advanced electrostatic precipitators and intelligent classification cyclones to ensure that oversize particles are eliminated, preventing defects in final industrial applications.
By optimizing energy consumption patterns and maximizing feedstock yield, YANXA ensures highly cost-effective manufacturing without sacrificing chemical purity. This is critical for international buyers who must manage tight margins while meeting strict regulatory standards such as REACH, RoHS, and local military/industrial specifications.

At YANXA, we believe that quality, safety, and efficiency prevail over all other factors in our business operations. The chemical sector demands a heightened awareness of environmental and safety hazards. Sub-micron and micronized metal powders, including 1.5 micron aluminum powder, are classified as flammable solids. Under the UN GHS system, their transport, storage, and handling require specialized procedures to mitigate the risk of dust explosions.
To ensure human health and environmental protection, YANXA packs all energetic powders under argon or nitrogen gas shielding inside hermetically sealed steel drums. Furthermore, we provide detailed Safety Data Sheets (SDS), Certificates of Analysis (COA), and technical consultation on dust mitigation engineering and static grounding protocols to our international customers.
Since our founding as a small business unit in 2008, YANXA has grown into an international chemical supplier. Collaborating with top manufacturers and research institutes across China, we supply more than just aluminum powder. Our diverse portfolio includes:
