In cooperation with China's leading manufacturing units and renowned chemical research institutes, YANXA has built solid core competencies in supplying the following chemical and material categories:
Aluminum powder is a critical, multi-functional material utilized across a spectrum of cutting-edge sectors including additive manufacturing (3D printing), solar photovoltaics, thermite reactions, pigment formulation, and aerospace propulsion. Achieving maximum performance requires a deep control of powder morphology, particle size distribution (PSD), and surface chemistry.
The shape of the aluminum particle dictates its behavior. Spherical Aluminum Powders are predominantly produced via inert gas atomization. The spherical shape ensures excellent flowability and high packing density, which are essential for additive manufacturing (metal 3D printing) and solar metallization pastes. In contrast, Flake Aluminum Powders are manufactured via mechanical milling, often in the presence of lubricants. These flakes present high surface area and structural overlapping qualities, making them the standard choice for leafing and non-leafing metallic pigments, anti-corrosive coatings, and aerated autoclave concrete (AAC) production.
To produce spherical powders with narrow particle size distribution, YANXA utilizes advanced gas atomization technology. By using high-pressure inert gases (nitrogen or argon), the molten aluminum stream is disintegrated into microscopic droplets that solidify rapidly in flight. This process minimizes oxygen pickup, resulting in clean powder with an active aluminum content of over 99%. Precision control over gas-to-metal ratios and nozzle geometry allows us to customize particle sizes down to D50 of 5-10 microns for electronic paste applications, or larger distributions (e.g., 45-105 microns) tailored for powder metallurgy and thermal spraying.
| Powder Type | Production Technology | Key Morphological Feature | Primary Application Areas | Critical Spec Target |
|---|---|---|---|---|
| Spherical Al-Powder | Inert Gas Atomization | High sphericity, smooth surface | Additive manufacturing, solar cell paste | Active Al > 99%, low oxygen (<0.15%) |
| Flake Zn-Al Alloy | Mechanical Ball Milling | Platy structure, high aspect ratio | Anti-corrosion coatings, marine paints | Excellent leafing properties |
| Al-Mg Alloy Powder | Atomization / Crushing | Homogeneous alloy phase | Refractories, pyrotechnics, metallurgy | Precise Al:Mg ratio configuration |
The industry is transitioning toward sub-micron and nanoscale powders. Nano-aluminum offers explosive reaction kinetics and enhanced sintering capabilities, though it requires specialized organic passivation coatings to prevent premature oxidation. Simultaneously, the green transition demands zero-carbon metallurgy. YANXA is actively collaborating with research institutes to develop recycling-based clean melting practices and water-resistant passivated aluminum powders that allow safe formulation in water-borne coatings, drastically reducing VOC emissions.
Operating out of China’s highly integrated industrial clusters, YANXA leverages the structural advantages of "China Factory 4.0" to deliver reliable supply security and competitive pricing to international buyers. Our cooperative production plants deploy state-of-the-art automation and strict environmental protection measures to guarantee consistent output regardless of seasonal energy adjustments or raw material volatility.
Closed-loop inert gas recycling systems, real-time particle monitoring, and automated packaging systems ensure absolute batch-to-batch consistency and high production safety.
Direct relationships with primary aluminum liquid smelters eliminate middle-man costs and minimize oxidation variables during processing.
Advanced dust collection systems, safety venting structures, and modern waste treatment enable our operations to run continuously under strict global eco-standards.
Furthermore, China's vast logistics network enables containerized hazardous shipments to reach major coastal ports (like Shanghai, Qingdao, and Tianjin) within 24-48 hours. By utilizing optimized sea routes and established multimodal transport, we mitigate supply chain disruptions and lower freight overheads for overseas purchasers.
Specialty metal powders and raw chemical materials are the backbone of modern infrastructure, manufacturing, and green-energy sectors. YANXA’s product range is optimized to support several primary macroeconomic segments:
The photovoltaic industry relies heavily on aluminum paste to form the back surface field (Al-BSF) in silicon solar cells. This electrical contact layer must exhibit high conductivity and outstanding adhesion characteristics. Our spherical aluminum powders, engineered with tight PSD control and ultra-low trace iron impurities, are tailored to maximize the light-to-electricity conversion efficiency of solar panels.
For industrial structures, marine vessels, and automotive parts, corrosion is a multi-billion dollar challenge. Flake zinc-aluminum alloy powders and zinc flake powders form overlapping galvanic barrier layers in coatings. These barriers prevent moisture and corrosive chloride ions from reaching the underlying steel substrate, significantly extending the operational lifespan of critical infrastructure.
In steelmaking and glass manufacturing, refractories are exposed to extreme thermal shocks. Incorporating atomized spherical aluminum-magnesium (Al-Mg) alloy powder improves high-temperature resistance and slag erosion protection. During heating, the metal particles form spinel structures (MgAl2O4) in situ, closing pores and enhancing mechanical toughness.
Below is a technical breakdown of several high-demand chemical and raw material lines managed by YANXA, showcasing our commitment to transparent, detailed, and highly specialized product data.
Formaldehyde: A highly reactive, colorless chemical intermediate, easily polymerized, and readily soluble in water, alcohol, and ether. In air, it is rapidly oxidized to formic acid, behaving as a powerful reducing agent. Commercially supplied as Formalin (a 37% to 50% solution stabilized with methanol to prevent polymerization). Freezing point: -118℃; relative density: 0.815 at -20℃; flash point: 55℃.
Paraformaldehyde Powder 96%: A linear polymer of formaldehyde characterized by a white powdery solid state and a distinct, flammable formaldehyde odor. It is widely used in resin synthesis, agricultural chemicals, and organic synthesis where water content must be minimized.
