FAQ

Q

How about the shipping fees?

A The shipping cost depends on the way you choose to get the goods. Express is normally the most quickest but also the most expensive way. By sea, freight is the best solution for big amounts. Exactly freight rates we can only give you if we know the details of the amount, weight, and way. Please contact us for further information.
Q

Do you guarantee safe and secure delivery of products?

A Yes, we always use high-quality export packaging. We also use specialized hazard packing for dangerous goods and validated cold storage shippers for temperature-sensitive items. Specialist packaging and non-standard packing requirements may incur an additional charge.
Q

What is the product warranty?

A We warranty our materials and workmanship. Our commitment is to your satisfaction with our products. In warranty or not, it is the culture of our company to address and resolve all customer issues to everyone’s satisfaction
Q

What kinds of payment methods do you accept?

A You can make the payment to our bank account, Western Union or PayPal: 30% deposit in advance, 70% balance against the copy of B/L.
Q

What is the average lead time?

A For samples, the lead time is about 7 days. For mass production, the lead time is 20-30 days after receiving the deposit payment. The lead times become effective when (1) we have received your deposit, and (2) we have your final approval for your products. If our lead times do not work with your deadline, please go over your requirements with your sale. In all cases, we will try to accommodate your needs. In most cases, we can do so.
Q

Can you supply the relevant documentation?

A Yes, we can provide most documentation including Certificates of Analysis / Conformance; Insurance; Origin, and other export documents where required.
Q

Do you have a minimum order quantity?

A Yes, we require all international orders to have an ongoing minimum order quantity. If you are looking to resell but in much smaller quantities, we recommend you check out our website.
Q

What are your prices?

A Our prices are subject to change depending on supply and other market factors. We will send you an updated price list after your company contacts us for further information.
Q

What are the performance parameters of amorphous cores?

A

1. Saturated magnetic induction intensity (Bsat): Saturated magnetic induction intensity refers to the maximum value at which the magnetic induction intensity of a magnetic core material reaches saturation under the action of an external magnetic field. A higher saturation magnetic induction intensity means that the magnetic core material can store more magnetic energy and has a higher magnetic saturation ability.

2. Coercivity (Hc): Coercivity refers to the external magnetic field strength required to reduce the magnetic induction intensity of a magnetic core material to zero under the action of demagnetization. A higher coercivity means that the magnetic core material has a higher anti-magnetization ability and can maintain stable magnetic properties under the action of an external magnetic field.

3. Hysteresis loss (Pv): Hysteresis loss refers to the energy loss generated by magnetic core materials during magnetization and demagnetization processes. Lower hysteresis loss means that the magnetic core material has lower energy loss and can provide higher energy conversion efficiency.

Q

What is the application of amorphous cores?

A

1. Transformers and inductors: Amorphous cores are widely used in transformers and inductors. Its high saturation induction intensity and low hysteresis loss give it advantages in efficient energy conversion and electrical energy transmission. The low hysteresis loss of amorphous magnetic cores can reduce energy loss and improve system efficiency.

2. Power electronics applications: Amorphous cores are also widely used in the field of power electronics, such as switch-mode power supplies, frequency converters, motor drivers, etc. Amorphous cores can provide efficient electrical energy conversion, while also having lower temperature rise and thermal dissipation, which helps to improve the stability and efficiency of the system.

3. Sensors and detectors: Due to their high magnetic permeability and low hysteresis characteristics, amorphous cores are widely used in sensors and detectors. For example, used in magnetic sensors, current sensors, magnetic memory, and magnetic stripe read/write heads.

Q

What are the differences between nanocrystalline cores and
other soft magnetic materials?

A

1. Preparation process: The preparation of nanocrystalline cores usually adopts special processes, such as rapid solidification, sol-gel, and heat treatment. The preparation process of traditional soft magnetic materials is relatively simple. The preparation process of nanocrystalline cores requires higher technical requirements and cost investment.

2. Magnetic permeability( μ): Nanocrystalline cores typically have higher magnetic permeability, which means they can more effectively conduct and concentrate magnetic fields. In contrast, traditional soft magnetic materials have lower magnetic permeability. High magnetic permeability enables nanocrystalline cores to provide better performance in applications such as sensors and inductors.

3. Magnetic saturation induction intensity (Bs): Nanocrystalline cores typically have higher magnetic saturation induction intensity, which means they can store more magnetic energy. In contrast, traditional soft magnetic materials have lower magnetic saturation induction intensity. This gives nanocrystalline cores advantages in efficient energy conversion and energy storage applications.

Q

What are the advantages of nanocrystalline cores ?

A

1. High saturation magnetic induction intensity: Nanocrystalline cores have a high saturation magnetic induction intensity, which means they can store more magnetic energy. This enables nanocrystalline cores to have higher efficiency and smaller volumes in energy storage and conversion applications.

2. Low hysteresis loss: Nanocrystalline cores have low hysteresis loss, which means that the energy loss generated during magnetic field changes is relatively small. This means that in high-frequency applications, nanocrystalline cores can reduce energy loss and heat generation, and improve system efficiency and stability.

3. High-temperature stability: Nanocrystalline cores have good high-temperature stability and can maintain their magnetic performance in high-temperature environments. This gives nanocrystalline cores advantages in high-temperature applications, such as high-temperature power electronic devices and automotive electrification.

Q

What are the advantages of powder core?

A

1. High magnetic permeability and low core loss improve the efficiency of magnetic devices;

2. Excellent temperature stability ensures stable performance over a wide temperature range;

3. High saturation magnetic induction strength, suitable for high-performance applications.

Q

What is the difference between powder core and traditional core?

A

Powder cores have higher magnetic permeability and lower core losses compared to traditional silicon steel cores. They can also achieve more complex shape and size designs,suitable for high-frequency applications, and have better temperature stability

Q

What is the working temperature range of powder core?

A

The working temperature range of powder cores usually depends on the specific product and material composition. In general, powder cores can operate normally within the temperature range of -40 ° C to+200 ° C.
