汽车启动电机用高H_(CJ)永磁铁氧体材料

High H_(CJ) Permanent Ferrite Material Used in Starting Motor of Automobile

用在汽车启动电机上的永磁铁氧体材料需有高内禀矫顽力ＨＣＪ，通过配方调整，添加附加成分，采用合理的工艺，制得的永磁铁氧体内禀矫顽力达３８０ｋＡ／ｍ ，杜绝了低温退磁现象。

Starting motor of automobile needs high H CJ permanent ferrite materials.By adjusting the formula,adding additives,adopting reasonable technique,permanent ferrite magnets with intrinsic coercive force of 380kA/m were developed,which eliminates the demagnetization at low temperature,and have satisfied the needs of the starting motor of automobile.
