*Ferrite: Ferrite is an oldest magnet mauterial and also is most widely used at present It is also called black mangnet.Its maximum magnetic energy is low,Website:http://www.ceramic-metal-parts.com,but its excellent temperature proof,steady property,cheap pricedetermine its wide usage in the speakers,motors,sensors,medical devices. In order to suit the export,we have set up our own ferrite production base in JiaXing and Dongyang.The annual output has reached over 10,000 tons.*Ferrite Magnet Characteristics:Our GRADEGRADEBr Remanence(mT)Hcb Coercivity(kA/m)Hcj Intrinsic Coercivity(kA/m)(BH)max Max Energy Product(kJ/m³Reference GRADEY08TY8T200-235125-160210-2806.5-9.5C1,HFS/22,FB1AY22HY22H310-360220-250280-32020.0-24.0FB2B,FXD270Y25Y25360-400135-170140-20022.5-28.0HF24/16Y26HY26H-1360-390200-250225-25523.0-28.0HF24/23,FB3X,FXD330Y26JY26H-2360-380263-288318-35024.0-28.0C7,EB3G,FXD405Y27HY27H350-380225-240235-26025.0-29.0Y28Y28370-400175-210180-22026.0-30.0C5,HF26/16,HF28/16Y28HY28H-1380-400240-260250-28027.0-30.0HF26/24,FB3NY28JY28H-2360-380271-295282-30526.0-30.0C9,FXD410Y30HY30H-1380-400230-275235-29027.0-32.0C8,HF28/26,FB4B,FXD380Y30JY30H-2395-415275-300310-33527.0-32.5C12,HF28/28,FB4G,FB5HY32Y32400-420160-190165-19530.0-33.5C10,HF30/16,FB4A,FXD300Y32HY32H-1400-420190-230230-25031.5-35.0C8B,FB4DY32JY32H-2400-440224-240245-26031.0-34.0FB4X,FXD400Y33Y33410-430220-250220-25031.5-35.0Y33HY33H410-430250-270250-27531.5-35.0HF30/26,FB5B,FXD520Y34Y34420-440200-230205-23532.5-36.0C11,FB4N,FXD425Y35Y35430-450215-239217-24133.1-38.2FB5NY36Y36430-450247-271250-27435.1-38.3FB5BY38Y38440-460285-305294-31036.6-40.6FB6NY40Y40440-460330-354340-36037.5-41.8*Ferrite Physical Properties:Pelative Recoil Permeability1.05-1.3Density4.7-5.0g/cm³Curie Temp450℃Electric Resistivity≥10000Ω*mTemp Coeff of Br Br -0.2%/℃Temp Coeff of Hcj Hcj0.2%-0.5%/℃Viker Hardness480-580HvCompositioinMO.6Fe2O3(M means Ba，Sr or their mixtureLinear Expansion Coefficient7-15×10-6/℃Specific Heat0.2kCal/（kg*℃）Flexural Strength0.5-0.9×10³N/m³Compressive Strength＞9×108N/m³Tensile Strength0.2-0.5×108N/m³
