FAQ

Q: Are you trading company or manufacturer ?

A: We are an integrated manufacturer of magnetic components, encompassing research and development, production, and sales. We provide customers with one-stop energy-saving, high-efficiency electronic component technology solutions.

Q: Can I get samples?

A: Samples order testing is supported, which help customers understand the performance and quality of core's products more intuitively.

Q:.How long is the sample lead time?

A: For ready samples, it's about 2-3 days. If you require your own size, it takes about 7 days.

Q: How long is the production lead time?

A: Generally it is 5-10 days if the products are in stock. Or 15-30 days if the goods are not in stock, depending on order quantity and production schedule.

A: Total amount ≤ USD5000, 100% pay in advance. Total amount > USD5000, 30% T/T in advance ,balance pay off before shipment. 
    The L/C is accept for big order, it can be negotiable. 

FAQ for Materials

Q: What Effect Does Heating The Magnetic Material Have?

A: Magnetic materials properties are temperature dependent. When temperature rises the magnetic interaction in the materials reduces due to thermal energy enhancement. When thermal energy overcomes the magnetic energy , magnetic property will reduce drastically or become zero.

Q: What is 1K107 Nanocrystalline Alloy material? Where can it be used?

A: 1K107 Nanocrystalline Alloy is an industry reference material, with different characteristics than proprietary alloys. When the specification or the application calls for a magnetically soft or high permeability material, 1K107 Nanocrystalline Alloy can frequently be successfully applied.

Q: Why must 1K107 Nanocrystalline Alloy  be final annealed to develop magnetic shielding performance?

A: To obtain optimum magnetic properties, annealing MuMetal® alloy following fabrication is essential. This should be done in a furnace that allows for careful control of the annealing temperature and cooling rate. Optimum properties are reached in a pure hydrogen atmosphere.
Q.5. Why does MuMetal or Co-Netic not be used at cryogenic temperature?

Q: What are the limitations on using 1K107 Nanocrystalline Alloy material?

A: The main limitation of the material is its high core loss at 50 Hz when compared with other soft magnetic materials.

Q: Why is coating required for parts made from 1K107 Nanocrystalline Alloy material?

A: SiFe materials are more prone to corrosion hence, to avoid corrosion, rusting or oxidation, coating is highly recommended for SiFe materials based components
