Anisotropic ferrite powder for mading high energy flexible rubber magnetic strip, hard magnet Y40, made from strontium ferrite
Unimagnet manufacture strontium ferrite powder which be considered as a environment friendly magnetic material, lead free and ROHS warranty. The strontium ferrite are using to produce various kind of hard and flexible magnets more and more widely, especailly in fridge door magnetic extrusion and acoustic magnetic sheeting. More than 28 years experience dedicated in ferrite industry since 1982, welcome your any interesting.
