一、产品介绍（introduction）： 

公司年产高精度antainano^® 纳米晶带材3000吨。antainano^® 纳米晶带材主要由铁、硅、硼、铜、铌等元素组成，在10⁶℃/s的冷却速度下制备，经特定退火工艺处理后，获得具有超细尺寸晶粒（~10nm）的软磁合金材料。

此类新型金属功能材料的显著特点是：生产制造流程短，一步成型，节约能耗；其突出优点在于兼备了铁基非晶合金的高饱和磁感应强度（bs）和钴基非晶合金的高磁导率和低损耗，能够很好地满足高频低损耗的性能要求。主要用于制作高端共模电感、高频变压器、各类电流互感器以及高端磁放大器等产品；相关铁芯器件主要应用于新能源汽车电能管理系统、驱动系统、手机无线充电模块、轨道交通、除尘电源、光伏发电并网逆变器、数字电子产品、电网中的智能电表等，以满足电力电子技术向高频、大电流、小型化、节能等发展趋势的要求。  

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.

五、磁滞回线和偏磁特性（hysteresis loop and dc-bias property）： 

1.磁滞回线(hysteresis loop)

纳米晶带材的磁导率在一定范围可调，不同磁导率对应的抗饱和能力不同。目前安泰科技可提供以下磁导率变化范围的材料定制化pg电子平台的解决方案。

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.

相对磁导率：μ=1,500~300,000 relative permeability：μ=1,500~300,000

抗饱和磁场：hm=30~350 a/m saturated magnetic field：hm=30~350a/m

2.偏磁特性(bias magnetic property)

六、不同厚度带材性能比较（performance comparison of different ribbon thickness）：

1.损耗特性曲线-频率(loss-frequency characteristic)

同种成分的纳米晶合金带材,在中高频率下，带材越薄，损耗越低，进而降低器件的温升，避免烧损。

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.损耗特性曲线-bm(loss-bm characteristic)

同种成分的纳米晶合金带材，在相同bm下，带材越薄，损耗越低。

for antainano^® alloy ribbon with same composition,  the thinner ribbon has the lower core loss at the same bm.

3.磁导率频率特性曲线(permeability)

同种成分的纳米晶合金带材，带材越薄，高频磁导率越高，阻抗越高，可使器件获得更好的emc效果。

for antainano^® alloy ribbon with same composition,the thinner ribbon has the higher permeability and impendance at higher frequency, which results in good emc performance of components .
