Electromagnetic material

Nippon koshuha’s high performance material supports advanced technology.

The advance of automization and electronic control in industrial / household use equipment are remarkable. The magnetic property and corrosion resistance are strongly requested from the solenoid valve and the solenoid used for them. Nippon Koshuha is offering GDM series and KTAS series as an electromagnetic material for high corrosion resistance.
