Magnetic fluid materials have broad application prospects and the competitiveness of Chinese enterprises is constantly improving

Magnetic fluid materials, also known as magnetic liquid materials, magnetic fluid materials, etc., refer to stable colloidal system materials composed of ultrafine magnetic particles highly dispersed in a carrier liquid through surfactants. Magnetic fluid materials combine the strong magnetism and conductivity characteristics of solid magnetic materials and the fluidity characteristics of liquid magnetic materials. They also have the advantages of high reliability, long service life, and good torque output. They are widely used in electronics, aviation, machinery, and environmental protection. It has broad application prospects in , medical, energy and other fields.

The core of magnetic fluid materials is ultrafine magnetic particles. Their shape and size are important factors affecting the performance of magnetic fluid materials, so their production requirements are high. At present, the common ultrafine magnetic particle materials mainly include iron oxide, nickel oxide, cobalt-iron alloy, ferric oxide, etc.; the main production methods include vacuum evaporation method, chemical co-precipitation method, discharge method, thermal decomposition method, etc. Among them, the chemical coprecipitation method has the advantages of simple operation and high yield, and is the most commonly used method for producing ultrafine magnetic particles.

Magnetic fluid materials are a new type of functional materials with a wide range of applications. In the medical field, magnetic fluid materials can be used in magnetic resonance imaging, enzyme immobilization, cell biology, immunoassays, affinity chromatography and other scenarios; in electronics, In the fields of machinery and other fields, magnetic fluid materials can be used as sealing materials for electronic component packaging, mechanical parts sealing and other scenarios. They have zero leakage, low usage, no pollution, and long life. In the field of environmental protection, magnetic fluid materials can be used for cleaning. Scenarios such as oil pollution in water bodies, removal of dyes from wastewater, adsorption of heavy metal elements or radioactive elements.

According to the “2023-2028 Magnetic Fluid Materials Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center, The global magnetic fluid sealing materials market size will reach US$270 million in 2022, a year-on-year growth of 5.5%. In the future, as research continues to deepen, more advantageous properties of magnetic fluid materials will be developed, and its application fields are expected to continue to expand. Mineral sorting, water-carrying fluids, and biomedicine are the main directions for future research on magnetic fluid materials, and the market development prospects are good.

Globally, the main manufacturers of magnetic fluid materials include American FerroLabs, American Elements, Germany’s ZF Group and other international companies, as well as Hunan Weige Magnetic Fluid, Hunan Xishan Magnetic Fluid Technology, Changzhou Yuanxiang Magnetic Fluid Technology, Zhuzhou Dajing Magnetic Fluid Technology, Hunan Henkel Magnetic Fluid Technology, Penglai Feiros Constant Magnetic Fluid, Hunan Xishan Magnetic Fluid Technology, Kunming Magnetic Fluid Technology and other Chinese companies.

Industry analysts said that from the perspective of the domestic market, my country’s magnetic fluid material research started relatively late. However, as local enterprises continue to upgrade their technologies and strengthen their competitiveness, they are gradually entering the field of high-end magnetic fluid application technology, showing a tendency to catch up from behind, and the market development potential is huge.
