Fe-Si Core is made form 94%Fe and 6% Si. It has a saturation flux density of 16000Gs and permeability from 14 to 90.A true high temperature material, with no thermal aging, Fe-Si Core offers lower core losses than powdered iron cores and superior DC Bias performance. Fe-Si Core also has excellent temperature stability and high energy storage capability. Fe-Si Core is mainly used in PFC circuit, power inductor etc.It's widely used in the renewable energies such as solar / PV, wind energy and hybrid powered vehicles as well as telecommunications' power supplies, server power supplies, UPS, etc., serving as power factor correction choke (PFC choke), switching regulator inductor, high current power choke, power inductor for energy storage, output inductor for general industrial power supplies, in-line noise filter / EMI filter. Main features: High Saturation Flux Density (16,000 Gauss) Excellent DC-bias Characteristics Excellent Thermal Stability Without Aging Problem Stable quality and good conformity Main applications: Industrial Power Supply PV Inverter Uninterruptible Power Supply Craftsmanship Sendust core are formed by adding a certain amount of glass forming agent to the molten metal, and rapidly quenching and casting using a narrow ceramic nozzle under high temperature melting conditions. Amorphous alloys have the similar characteristics of glass structure, which not only make them have excellent mechanical properties, physical properties and chemical properties, but more importantly, the new technology of producing amorphous alloys using this rapid quenching method is less than the cold-rolled silicon steel sheet process. 6 to 8 processes can save energy consumption by 60% to 80%, which is an energy-saving, time-saving and efficient metallurgical method. Moreover, the amorphous alloy has low coercivity and high magnetic permeability, and its core loss is significantly lower than that of oriented cold-rolled silicon steel sheet, and its no-load loss can be reduced by about 75%. Therefore, the use of amorphous alloys instead of silicon steel sheets to manufacture transformer cores is one of the main means to save energy and reduce consumption in today’s power grid equipment.
