1. High Magnetic Permeability

Our Permalloy Soft Magnetic Alloy Rod Ni79mo4 is designed with high magnetic permeability, meaning that it is capable of conducting magnetic energy efficiently. This characteristic makes it an excellent choice for applications that require high magnetic flux density, allowing it to work effectively with electromagnetic fields.

2. Low Coercivity

Another essential feature of our product is its low coercivity, which refers to the amount of magnetic field strength required to demagnetize the material. Our alloy rod requires relatively low fields to demagnetize, making it ideal for applications requiring rapid switching.

3. Low Hysteresis Loss

Our Permalloy Soft Magnetic Alloy Rod Ni79mo4 has low hysteresis loss, which refers to the energy loss that occurs when the magnetization of the material changes. This feature makes our product more efficient, allowing it to conserve energy and minimize heat production during operation.

4. High Saturation Induction

Our alloy rod has a high saturation induction, meaning it can carry a high magnetic field without becoming magnetized. This feature is critical for applications that require high magnetic energy storage, such as transformers and inductors.

5. Excellent Corrosion Resistance

Our product is manufactured with materials that are resistant to corrosion, making it ideal for use in environments prone to corrosion. This feature ensures that our product remains durable, efficient and does not degrade over time, even when exposed to harsh conditions.
