A Legacy of Metallurgical Excellence
Pioneering the future of additive manufacturing with decades of material science expertise.
Established in 1997, Hunan Ningxiang Jiweixin Metal Powder Co., Ltd. is a globally recognized hi-tech enterprise dedicated to the R&D and production of spherical Aluminium powder, Aluminium-based alloy powders, and advanced metal composites. In December 2009, our technological capabilities were further amplified when the company was jointly acquired by the prestigious Toyo Aluminium K.K Group and Shanghai Matsuo Co., Ltd.
Located in the Ningxiang State-level Economic Development Zone, Hunan Province, China, our state-of-the-art manufacturing facilities produce materials that drive innovation across multiple sectors. Beyond 3D printing materials, our extensive portfolio serves critical applications including aluminium metal matrix composites, high-end metallic pigments, thermal and electric conductive materials, solar energy Aluminium paste, negative electrode materials for lithium batteries, powder metallurgy, sputtering targets, and corrosion-resistant metallic coatings.
Why Our Foundation Matters for 3D Printing
Metal Additive Manufacturing (AM) demands absolute precision at the microscopic level. Our decades of experience in synthesizing complex chemical catalysts, refractory materials, and aerospace-grade aluminium nitride directly translate into the unparalleled quality of our AlSi10Mg powder. We don't just blend metals; we engineer microstructures that guarantee flawless laser fusion, ensuring your final printed parts meet the most stringent global standards.
The Perfect Balance: Understanding AlSi10Mg
Why has this specific alloy become the gold standard in Selective Laser Melting (SLM) and Direct Metal Laser Sintering (DMLS)?
The Role of Silicon (Si)
AlSi10Mg contains approximately 10% Silicon. This near-eutectic composition significantly lowers the melting point and drastically reduces the shrinkage rate during the rapid cooling phase of laser melting. This means virtually zero hot-tearing or cracking, allowing for the successful printing of highly complex, thin-walled geometries.
The Power of Magnesium (Mg)
The addition of a small amount of Magnesium (around 0.3-0.5%) transforms the alloy. Magnesium enables age-hardening (precipitation hardening). After standard heat treatments, Mg2Si precipitates form within the aluminium matrix, exponentially increasing the tensile and yield strength without severely compromising the material's natural lightweight properties.
Exceptional Post-Print Properties
Once printed, AlSi10Mg parts exhibit a phenomenal combination of low density, outstanding mechanical strength, excellent thermal conductivity, and superb corrosion resistance. It bridges the gap between traditional die-casting aluminium and the futuristic demands of topological optimization.
Transforming Global Industries
We invite partners across the Automotive, Aerospace, and Tooling sectors to explore the infinite possibilities of 3D printing with our premium powders.
Automotive & EV Revolution
In the race for electric vehicle (EV) supremacy, lightweighting is critical. AlSi10Mg is extensively used to manufacture topologically optimized brackets, complex internal fluid channels, heat exchangers, and motor housings. It achieves significant weight reduction while maintaining structural integrity, accelerating R&D iterations and boosting EV battery range.
Aerospace & Defense
Aerospace engineering demands the ultimate buy-to-fly ratio and extreme reliability. Our powder meets stringent aviation standards, enabling the fabrication of weight-critical components such as waveguides, sensor housings, and intricate hydraulic routing manifolds. The stable mechanical properties ensure performance even in the most demanding atmospheric conditions.
Tooling & Injection Molding
Revolutionize your manufacturing cycle times. By utilizing AlSi10Mg for mold inserts, engineers can design complex conformal cooling channels that perfectly follow the geometry of the molded part. This drastically shortens the cooling cycle, reduces part warpage, and significantly elevates injection molding efficiency and end-product quality.
Our Core Manufacturing Advantages
As a direct manufacturer, we provide more than just powder. We provide peace of mind, consistency, and a partnership geared towards your success.
1. Unwavering Supply Stability
In a volatile global market, supply chain security is paramount. As a primary production enterprise backed by the Toyo Aluminium K.K Group, we possess massive, scalable manufacturing capacity. We eliminate the middleman, ensuring that whether you need 10 kilograms for prototyping or 10 tons for serial mass production, your supply lines remain uninterrupted. Our robust logistics network guarantees on-time delivery to global partners.
2. 100% Traceability & Batch-to-Batch Consistency
Variability is the enemy of additive manufacturing. Our production operates under a rigorous ISO 9001 certified quality management system. Every single batch of AlSi10Mg powder is digitally tracked from raw aluminium ingot selection to advanced gas atomization, and finally to vacuum-sealed packaging. We guarantee tight control over particle size distribution (PSD), morphology, and chemical composition, ensuring that Part A printed today is identical to Part A printed five years from now.
3. Tailored Customization & Joint R&D
Innovation doesn't fit in a standard box. While we offer mainstream particle size specifications (such as 15-53µm and 20-63µm compatible with EOS, SLM Solutions, BLT, and Farsoon), we excel in bespoke solutions. Need a specialized alloy tweak for enhanced thermal resistance? Require a unique particle size distribution for a proprietary binder jetting or directed energy deposition (DED) system? Our R&D team engages in joint application development to conquer your most complex geometric and metallurgical challenges.
Technical Specifications & Performance
Engineered via advanced gas atomization technology, our powder exhibits extremely high sphericity and exceptional flowability. We strictly control the ultra-low oxygen content to prevent balling effects and slag inclusions during printing, guaranteeing high density and superior static mechanical properties.
| Mechanical Property | Typical Value (Heat Treated) | Standard Reference |
|---|---|---|
| Tensile Strength (Rm) | ≥ 460 MPa | Meets ASTM F3318 Requirements |
| Yield Strength (Rp0.2) | ≥ 270 MPa | Meets DIN EN 1706 Standards |
| Elongation at Break (A) | 8 – 12% | Perfect Balance of Strength & Toughness |
