Low Core Loss Alloy Powder Core

Low Core Loss Alloy Powder Core

GMC has designed standard packaging for shipment to customers around the world.We recommend the cores remain in the original factory packaging and be sheltered from rain or high humidity since uncoated iron can eventually form surface tust.

G&M is able to customize the design to meet customers’ requirements.

Transport and storage(AS):

GMC has designed standard packaging for shipment to customers around the world.We recommend the cores remain in the original factory packaging and be sheltered from rain or high humidity since uncoated iron can eventually form surface tust.Magnetic powder cores tend to be heavier than many other products and special conside ration must be given to the weight of the carton.Do not stack more than 5 cartons high to avoid crushing the bottom cartons.Our normal packing box's weight is form 15 to 20kg.Please be aware the cores are quite dense and package size can be deceivingly heavy.Damage will occur to cores if they are dropped on a hard surface then a crack or chip can result on tne core coating.Special consideeration for electrostatic discharge is not necessary with magnetic powder cores since they have a 'distributed air gap structure' and will not retain an electrostatic charge.Finally,as with most magnetic material.magnetic powder cores need to be kept free of metal shacings,oil,solvents,dirt,dust and acides.
