                納米晶帶材 Nanocrystalline Ribbons

                高飽和磁感、高磁導率 High saturation magnetic flux density and high Permeability,低損耗 Low core loss,低矯頑力 Low coercive force,低磁伸 Low magnetostriction



                公司年產高精度Antainano? 納米晶帶材3000噸。Antainano? 納米晶帶材主要由鐵、硅、硼、銅、鈮等元素組成,在106℃/s的冷卻速度下制備,經特定退火工藝處理后,獲得具有超細尺寸晶粒(~10nm)的軟磁合金材料。


                The annual production of high-precision Antainano? ribbon is more than 3000 tons. With the composition of Fe、Si、B、Cu、Nb and other elements, through specific annealing process at cooling rate of 106℃/s, the soft magnetic alloy material with superfine grain size (~10nm) is obtained. 

                This new type of metallic functional material is characterized by short production process, one step forming and energy-saving consumption. It owns both features of high saturation magnetization (Bs) of Fe- based Antaimo? alloy and high permeability of cobalt-based Antaimo? alloy, thus it can well meet the performance requirements of high frequency and low loss.

                This material is mainly applied in the production of high-end common mode chokes, high frequency transformer, all kinds of current transformers and high-end magnetic amplifier, etc. Related cores and components are mainly used in new energy vehicle power management system, drive system, wireless charging module for mobile phone, rail transit, the precipitation power, grid-connected photovoltaic inverter, digital electronic products, and smart meters in the power grid, etc to meet the requirement of high frequency, huge current, smallness and energy-saving.

                1.磁滯回線(Hysteresis Loop)


                Antainano? ribbon permeability can be adjusted in a certain range. The DC-immune property of cores changes with varied permeability. At present, Antainano? can provide customized material solving method for permeability range as below.


                相對磁導率:μ=1,500~300,000 Relative permeability:μ=1,500~300,000

                抗飽和磁場:Hm=30~350 A/m Saturated magnetic field:Hm=30~350A/m

                2.偏磁特性(Bias Magnetic Property)


                六、不同厚度帶材性能比較(Performance Comparison of Different Ribbon Thickness)

                1.損耗特性曲線-頻率(Loss-Frequency Characteristic)


                For Antainano? alloy ribbon with same composition, the thinner ribbon is, the lower core loss is. Moreover, the temperature rise of components could be reduced in high frequency to avoid burning.


                2.損耗特性曲線-Bm(Loss-Bm Characteristic)


                For Antainano? alloy ribbon with same composition,  the thinner ribbon has the lower core loss at the same Bm.
