1. What is Nickel Iron Alloy 4750 Strip?

Nickel Iron Alloy 4750 Strip is a precision nickel-iron magnetic alloy containing approximately 47.5% nickel and iron as the balance. It is engineered for controlled soft-magnetic performance.

2. What is Nickel Iron 4750 Strip used for?

It is commonly used in magnetic cores, transformers, inductors, relays, sensors, electromagnetic shielding, magnetic components, and precision electrical devices.

3. What makes 4750 Nickel-Iron Alloy magnetic?

The controlled nickel-to-iron composition gives the alloy useful soft-magnetic characteristics, while processing and heat treatment determine permeability, coercivity, hysteresis losses, and other final magnetic properties.

4. Can the magnetic properties be customized?

Yes. Magnetic performance can be influenced through composition, cold reduction, annealing, grain structure, and final heat treatment. Specific permeability, coercivity, saturation, or core-loss requirements can be incorporated into the purchasing specification.

5. Can the strip be supplied in custom dimensions?

Yes. REG Metals can source custom thicknesses, widths, slit widths, coil weights, tempers, edge conditions, surface finishes, and dimensional tolerances.

6. Does REG Metals provide a Certificate of Analysis?

Yes. A Certificate of Analysis (COA) can be supplied documenting nickel and iron composition, trace impurities, thickness, dimensions, mechanical properties, magnetic properties where specified, heat treatment, and lot/coil information.
