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.
Q: Which kinds of certificate would you have?
A: ISO9001, IATF 16949, RoHs, UL, MSDS and so on.
Q: What is your terms of payment ?
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
