Unimagnet provided UMWF series ferrite magnetic powder are used in manufacturing sintered magnets for higher energy products, typical application includes medium and higher speaker rings, NMR devices, magnettic seperators and automotive motors.
As an essential raw material of ferrite magnetic powder, iron oxide red acts a key role in the manufacture process of ferrite magnetic powder. For long time, Unimagnet has establish iternational co-operation with ASSI(US) and BaoSteel Group, and steady-going purchases high quality iron oxide red to guarantee stable purity , granularity,particle shape, bulk density and compactness of raw mateiral. Simultaneously, Unimagnet adopt constant and stable technics to ensure the ferrite magnetic powder with coherent magnetic performance, stable particle shape and narrow-dispersed size distribution.
