Yanxatech System Industries Limited (hereinafter referred to as YANXA) is one of the growing suppliers in the field of specialty materials in China. Starting from a fledgling small business unit in 2008, YANXA has been driven with the passion of developing a broad international market in areas relating to the chemical and mechanical industries.
Thanks to our team's enduring, persistent work and our business partners' long-lasting support, YANXA has steadily and vigorously grown into an industry leader with excellence in delivering premium specialty chemicals, advanced high-purity metal powders, and high-performance gas systems. We cooperate with leading manufacturers and the most renowned research institutes in China to supply state-of-the-art materials to demanding global sectors, including aerospace, defense, precision electronics, and high-frequency communication systems.
Connecting China's top-tier advanced manufacturing capabilities with global industrial demands since 2008.
Carbonyl Iron Powder (CIP) represents the absolute pinnacle of high-purity micro-sized metal metallurgy. Produced via the precise thermal decomposition of iron pentacarbonyl [Fe(CO)₅], this material exhibits highly spherical particles, onion-skin microstructures, and exceptional physical-chemical stability. As a premier wholesale carbonyl iron powder manufacturer & factory, YANXA delivers state-of-the-art particulate products specifically engineered for complex, high-frequency, and extreme-performance applications.
Technical Distinction: Unlike standard reduced or atomized iron powders, carbonyl iron powder is distinguished by its incredibly small particle sizes (typically 1–8 µm), spherical morphology, and exceptional chemical purity (total iron content ≥ 99.8%). This makes it the standard-bearer for electromagnetic interference (EMI) shielding, metal injection molding (MIM), and soft magnetic composites (SMC).
The following parameters represent YANXA's reference grades. Customized specifications regarding particle size distribution (PSD), carbon content, and surface treatments are available upon request:
| Grade Classification | Average Particle Size (d50) | Iron (Fe) Content | Carbon (C) Content | Primary Industrial Applications |
|---|---|---|---|---|
| CIP-S (Spherical Standard) | 3.5 – 5.0 µm | ≥ 99.8% | 0.65 – 0.85% | Metal Injection Molding (MIM), Soft Magnetic Composites |
| CIP-R (Reduced Fine) | 2.0 – 4.0 µm | ≥ 99.9% | ≤ 0.05% | High-Frequency Inductors, EMI Shielding, Powders Metallurgy |
| CIP-U (Ultra-Fine Grade) | 1.0 – 2.0 µm | ≥ 99.7% | 0.70 – 0.90% | Absorbing Materials, Radar Coatings, Specialty Chemical Catalysts |
The global metal powder industry is shifting towards sub-micron and nanostructured domains. The historical roadmap of Carbonyl Iron Powder has focused on micron-scale optimization for core electronics. Looking ahead, YANXA's technological projection focuses on three core innovations:
Reducing primary particle sizes to the sub-micron level (500nm - 800nm) to minimize eddy current losses at frequencies exceeding 100 MHz, vital for next-generation telecommunication grids and radar absorbing coatings.
Implementing hybrid inorganic/organic coating technologies (such as silane coupling agents and nano-silica shells) to improve thermal oxidation limits and maximize electrical resistivity in Soft Magnetic Composites (SMCs).
Developing mixed morphology assemblies that combine high-aspect-ratio carbonyl iron flakes with spherical micro-particles to maximize packing densities and create highly compact electromagnetic devices.
YANXA partners with downstream industries to deliver tailored raw material configurations, solving structural, electromagnetic, and mechanical challenges across diverse sectors:
Global supply chains demand absolute regulatory transparency and environmental compliance. YANXA ensures all manufacturing practices and chemical distributions align with contemporary global frameworks:
Our operations comply with the European REACH Regulation (Registration, Evaluation, Authorization, and Restriction of Chemicals) and RoHS (Restriction of Hazardous Substances) directives. We maintain updated Safety Data Sheets (SDS) in accordance with the Globally Harmonized System (GHS). For metal powders and nitrates, we provide exhaustive conflict-free mineral declarations and ISO 14001 certification traces, guaranteeing that your raw material procurement satisfies internal ESG benchmarks and international import standards.
YANXA leverage China's advanced industrial infrastructure by partnering with premier ISO9001:2008 certified manufacturing centers. Our operations utilize integrated Factory 4.0 principles, including:
We accommodate the specific requirements of international procurement offices through flexible commercial terms, comprehensive technical documentation, and rigorous quality assurance processes. Every shipment is accompanied by a Certificate of Analysis (COA) specifying the purity, D10/D50/D90 PSD, and elemental impurities. Sample qualification protocols are expedited to minimize testing cycles for new R&D or mass-production lines.
In addition to our advanced metallurgy lines, YANXA's legacy portfolio comprises high-purity chemical intermediates and industrial gases. Below are the historical product specifications preserved for engineering reference:
