We handle "ferrite sintered magnets." The main raw materials are inexpensive iron oxide and strontium carbonate or barium carbonate. In terms of magnetic properties, they have a high coercivity (Hcj) and are widely used in various applications. 【Features】 ■ High coercivity (Hcj) in terms of magnetic properties ■ Being a ceramic material, they are prone to cracking and chipping ■ The temperature coefficient of magnetic flux is -0.18%/°C, which is significantly larger than that of alnico magnets and samarium-cobalt magnets, requiring consideration for temperature effects *For more details, please refer to the PDF document or feel free to contact us.

Currently, traditional magnets are once again coming into the spotlight. One example of this research is the application of next-generation magnetic flux variable motor technology aimed at achieving higher efficiency in the fields of hybrid vehicles (HEVs) and electric vehicles (EVs). Traditionally, it has been considered good for magnets to have "strong and unchanging magnetic force," but this new approach is born from the idea that "easily changeable magnetic force" can also be a feature. Using this research as an example, I would like to introduce the future possibilities of magnets. [Case Study: Magnetic Flux Variable Motor] <Conventional Technology: Increased power consumption in high-speed rotation and low output> ■ Factor 1: Resistance loss due to weakened magnetic flux current ■ Factor 2: Forced reverse magnetic field 　→ Magnetic losses occur → Efficiency decreases 　　　　　　　↓ <New Concept Technology Research: Significantly reduce power consumption in high-speed rotation and low output> ■ Variable magnetic force technology that achieves reduction of magnetic losses → Changes the magnetic force of permanent magnets ■ Passing short pulses of electric current ⇒ Variable magnetic force of permanent magnets 　→ Significant reduction in magnetic losses → Increased efficiency ■ Research technology that eliminates the need for "weakened magnetic flux control," which is a challenge of conventional technology. *For more details, please refer to the PDF document or feel free to contact us.

Cast Alnico magnets have a high magnetic flux density (Br) and are materials that excel in heat resistance and temperature characteristics, making them widely used for many years. Sintered Alnico magnets have magnetic properties equivalent to cast magnets, yet they can achieve good surface finishes and dimensional accuracy for small, complex shapes without the need for polishing. Additionally, they provide uniformity of products in response to large-scale demand. 【Features】 ■ High magnetic flux density ■ Excellent heat resistance and temperature characteristics ■ Good surface finish and dimensional accuracy for small, complex shapes without polishing ■ Uniformity of products for large-scale demand *For more details, please request materials or view the PDF data from the download section.
