Evaluation Kits, Meters & Probes (LK-110)

Evaluation Lab Kits, Meters & Probes

(9)
"Hands-On" evaluation and sampling begins here. Using our Lab Kits, Meters & Probes, shielding can be prototyped with everyday common hand-tools, or bench- top and model-shop equipment. Layers of material from a Lab Kit can be added until the unwanted field is reduced (attenuated) to the desired level. Your prototype then serves as a production model. After prototyping, contact Magnetic Shield Corporation for a fabrication or stock material quotation.

Our Lab Kits include a variety of MuMETAL®, Co-NETIC®, and NETIC® alloy samples for testing and evaluation. Three Lab Kit options are available.

NOTE:  A discount can be applied for purchasing quantity lab kit orders ...
MuMETAL® Stress Annealed Sheet (MU014-24-120)

MuMETAL® | Foil, Sheet, Plate, Coil, Bar | & Products


MuMETAL® is our most widely known brand. For decades, many engineers, metal suppliers and fabricators have referred to it as the industry standard. However, MuMETAL® is a registered trade name and exclusively available from Magnetic Shield Corporation. We offer several other magnetic shielding alloys used for similar but different applications, yet MuMETAL® is the most specified.

MuMETAL® alloy is available in many forms, but most shields are fabricated from our plate, foil or sheet stock in gauges from 0.002" to 0.098" thickness [0,05mm to 2,5mm].

NEW:  MuMETAL® Stress Annealed Plate, a sheet form offered in thicker gauges is now available...Learn More

NEW:  Our stock Perfection Annealed MuMETAL® Foil is now available with .002" thick pressure sensitive adhesive backing (1-sided), with a release coated liner. Or uncoated foil may be selected.

RECENT:  MuMETAL® Deep-draw Coil and Round Mu-bar lines used in fabrication of enclosures and parts fabrication are stocked and ready for shipment.

Co-NETIC® Sheet and Foil

Co-NETIC® Sheet & Foil


CO-NETIC® is a proprietary alloy developed by Magnetic Shield Corporation specifically to provide effective magnetic shielding.

We stock two different formulations:
  • Co-NETIC® AA is used primarily in low intensity fields where high attenuation is desired (high initial permeability & high shielding efficiency). Available as either Stress Annealed or Perfection Annealed Sheet and as Perfection Annealed Foil, Co-NETIC® AA alloy is used for most shielding applications.
  • Co-NETIC® B Alloy (Medium Permeability) is used in slightly stronger fields with attenuation characteristics set between high permeability Co-Netic® AA and high saturation Netic® S3-6. It is useful in certain applications where the very high attenuation of Co-Netic® AA is not required. Stress Annealed for ease of manufacturing. Must be final hydrogen annealed as a final process to maximize shielding properties.

NEW:  Co-NETIC® B Stress Annealed Plate, a sheet form offered in thicker gauges is now available. Conforms to ASTM A753 Alloy 2, and MIL-N 14411C Comp 3...Learn More

NETIC® Sheet & Foil

NETIC® Sheet & Foil


NETIC® is a proprietary brand that is often applied in fields of high intensity (strong fields) because of its high magnetic saturation characteristics.

We stock three different types:
  • NETIC® S3-6 is an Uncoated, high iron shielding alloy, and is prone to oxidation. Typically this alloy is painted or plated after shield fabrication.
  • NETIC® S3-6 ET is Electro-Tin Plated and can be used as is. Both products are available as Sheet or Foil, and contain the same chemical composition and shielding efficiency.
  • NETIC® S3-6 PST is our high iron shielding alloy with added Pressure Sensitive Tape.

For ultimate performance, NETIC® is commonly used in combination (in layers) with Co-NETIC® or MuMETAL®. If used in combination, the NETIC® layer is placed closest to the source of interference, with Co-NETIC® or MuMETAL® layer closest to the component being shielded. Used for either fabricated or flat shields, it may be re-annealed for better performance.

CY040-24-78.7 Sheet

CRYO-NETIC® Sheet


NEW: CRYO-NETIC® is our proprietary nickel-iron soft magnetic alloy that is ideal for shielding unwanted magnetic fields at extremely low temperatures, typically 77 Kelvin (liquid nitrogen) and 4 Kelvin (liquid helium). Many high energy physics research applications are conducted under cryogenic temperatures, but still require shielding. The permeability of our MuMETAL® and Co-NETIC® alloys begin to decline at -40 degrees, which is why we offer our CRYO-NETIC® magnetic shielding alloy for increasing permeability with decreasing temperature.  These Stress Annealed Sheets are of soft temper for ease of fabricating shields such as enclosures, cylinders, cans, channels or 3D boxes. Please contact our technical sales team for your custom shielding quote.

Stress Annealed Sheet is stocked in gauges 0.040" and 0.059" thickness [1,0mm to 1,50mm].

NOTE: Priced per sheet. Volume discounts available.

Shearing: Stock sheet sizes can be sheared to your custom dimension specifications by indicating length & width.

Wiring Samples

Magnetic Shielding for Wiring Applications


We offer several magnetic shielding products used in electrical/electronic wiring applications such as: power feeds, aerospace, vehicle controls, test and measurement devices, audio-level interconnections, communication equipment, and hand-held devices.

Shielding: To provide effective magnetic shielding for cable and conductors such as twisted pair; and avoid pickup of external fields or radiation of interfering, unwanted fields use AA CABLE SHIELD® and SPIRA-SHIELD Flexible Conduit.

Cable: Our INTER-8® Weave Cable replaces and provides substantial improvement over conventional twisted-pair cables. INTER-8® Weave Cable consists of four separate conductors braided into interlocking loops and is a field-proven design of Magnetic Shield Corporation.

Wire: We also offer our Co-NETIC® AA Wire, which is used in fabrication of magnetic shielding braided sleeving to certain customer specifications where our stock
AA CABLE SHIELD® may not be specified.
MuMETAL® Round Bar

MuMETAL® Round Bar

(10)
MuMETAL® Round Bar is primarily used for CNC machined or forged components like custom tubing, current sensors, high precision current transformer cores, ground fault circuit breaker (relay parts), or any other applications requiring precision machining, high permeability soft magnetic alloy, with a low coercive force and low losses, in the range from 0-100 kHz. Ask about prototyping and small to large production runs. Atmospherically controlled Perfection Annealing is required after machining, forming, forging, or welding to provide maximum shielding performance.

Our MuMETAL® Round Bar is stocked unannealed in a hard state, in diameters from 0.250" to 8.17" [6,35mm to 207,5mm]. ...
