Permalloy Mesh for Magnetic Shield

Product Description:

Permalloy mesh is made of Permalloy, a nickel-iron (Ni-Fe) alloy known for its high magnetic permeability, low coercivity, and near-zero magnetostriction. These properties make it highly effective in magnetic shielding, sensors, inductors, and RF applications. It is a great solution in providing shielding from the variable frequency electric and magnetic waves. The square woven mesh acts as an equivalent sheet impedance operator. Its effectiveness in the plane wave shielding prevents the coupling effect between antennas in either side of the planar mesh. The extent of shielding provided is based on the geometry of enclosure, mesh size and wire radius.

Key Properties of Permalloy Mesh:

1. High Magnetic Permeability – Efficiently redirects magnetic fields, making it ideal for shielding.
2. Low Hysteresis Loss – Minimizes energy loss in alternating magnetic fields.
3. Soft Magnetic Material – Easy to magnetize and demagnetize.
4. Corrosion Resistance – Nickel content provides good durability in various environments.

Permalloy Magnetic Shielding Mesh Applications:

– Magnetic Shielding – Used in sensitive electronic devices (MRI machines, sensors) to block stray magnetic fields.

– RF & Microwave Devices – Helps in controlling electromagnetic interference (EMI).

– Transformers & Inductors – Enhances performance in high-frequency applications.

– Aerospace & Defense – Used in radar systems and communication equipment.

– Scientific Instruments – Shields particle detectors and precision measurement tools.

The magnetic shielding mesh is also rolled and can be utilized to replace standard reinforcement mesh to save money. It is specifically manufactured for easy handling even by an amateur.

Types of Permalloy Mesh:

– Woven Mesh – Made from thin Permalloy wires, offering flexibility.

– Expanded Mesh – Lightweight and used where structural rigidity is needed.
