Expert in High-Performance Soft Magnetic Material Solutions
Changsha Tianjiu Metal Materials Co., Ltd. focuses on the research and development and production of soft magnetic powder20year, providing core raw materials for soft magnetic materials with high permeability, low loss, and strong stability, empowering innovation and upgrading in the fields of electronics, power, new energy, and automotive electronics.
What are soft magnetic materials?
Soft magnetic materials are magnetic functional materials with low coercivity and high permeability. They can quickly respond to changes in external magnetic fields and efficiently complete the conversion of electrical energy to magnetic energy, widely used in the manufacture of electromagnetic components.
Core Characteristics:
- High Permeability: Fast magnetization, improved device efficiency
- Low Loss: Reduced eddy current and hysteresis loss, energy saving and consumption reduction
- Wide Frequency Adaptability: CoverskHztoMHzhigh-frequency scenarios
- Temperature Stability:-50℃~200℃ stable operation
Common Classifications:
- Metallic soft magnetic materials (iron silicon, iron nickel, iron-based amorphous)
- Ferrite soft magnetic materials (manganese zinc, nickel zinc)
- Composite soft magnetic materials (prepared by powder metallurgy)
The Core Role of Soft Magnetic Powder
Soft Magnetic Powder—The cornerstone of high-performance soft magnetic materials
Soft magnetic powder is the core raw material for preparing soft magnetic composite materials (SMC). Through insulation coating and precision pressing processes, it can significantly reduce eddy current loss and meet the needs of high-frequency and miniaturized devices.
