無線充電系列隔磁片
Magnetic Sheet for Wireless Charging
無線充電隔磁片以鐵基非晶／納米晶帶材為主要原材料製成， 非晶／納米晶隔磁材料具有高磁導率、高飽和磁通密度、無各向異性等特性， 無線充電效率可達 70% 以上，可製成 30–300 μm 的磁性薄片。 材料具有柔性，不易變形或碎裂。
Magnetic sheet for wireless charging is made of iron-based amorphous/nano-crystalline ribbons. The amorphous/nano-crystalline magnetic sheet features high permeability, high saturation induction and no anisotropy. Wireless charging efficiency can reach more than 70%. Magnetic sheets with a thickness of 30–300 μm can be produced. The flexible material helps prevent deformation and fracture.
