Our MuMETAL® Cans provide excellent low frequency magnetic field attenuation with low coercive forces and are used in many industries for protecting critical devices from magnetic interference, electromagnetic radiation and cross-talk signals.  Products using MuMETAL® magnetic shielding cans include high-end audio amplifiers, current transformers, specialty transformers and other distinct electrical/electronic & printed circuit board (PCB) components. Our cans are easily integrated into circuits so this shielding method may be found in audio, automotive, automation, power supply and power generation sectors.

There are many mild-steel Can manufacturers in the USA, but none carry inventory of MuMETAL® like we do or have the ability to anneal for magnetic performance.  With our extensive stock of MuMETAL®, forming tooling and heat treatment processes, we are most economical in delivery of deep-drawn cans and other enclosures. Other Can manufacturers purchase our high permeability (µ) 80% nickel-iron MuMETAL® alloy, Co-NETIC® B or NETIC® and outsource the soft magnetics annealing process needed for high quality magnetic shielding manufacturing.  Why not order finished cans from the source?  Magnetic Shield Corporation is the source for MuMETAL® Cans.

We offer a wide range of 5-sided magnetic shielding cans stamped or formed from our proprietary MuMETAL® shielding alloy or other shielding alloys.  Manufactured in either ROUND or RECTANGULAR shapes (sizes approximately 3/8” to 3” diameter or width), and deep-drawn up to a 3:1 depth ratio and pinch-trimmed when necessary, our standard stock range and custom sizes are available in shielding material thicknesses from 0.014’’ to 0.062’’ [0,36mm to 1,57mm thick]; and made from various MuMETAL®, Co-NETIC® B or NETIC® shielding alloys depending on your exact shielding requirements. Inside and outside flanged lids are available for most of our stock range cans upon request.

We also produce specific form tooling and custom size production cans for many of our clients. Manufacturing new tooling normally takes approximately six weeks before supply of the first prototypes for approval but we can produce hand-made prototypes of a new design in 2-3 weeks to verify the product prior to any tool cost being incurred.

All of our shielding enclosures can be supplied with either inside or outside tight fitting Lids, creating a 6-sided shielding enclosure. MuMETAL® Cans are not automatically supplied with Lids, if you require them for your application, please specify this at the time of placing your inquiry.  All of our Lids and Cans may be further machined to include holes/slots configured for your wiring requirements.

Typically, our high permeability (µ) 80% nickel-iron MuMETAL® cans are shipped as is since our AA Perfection Annealing method provides a bright nickel appearance after anneal.  We do offer other finishes including plating, electro-polish, powder coating and paint.

Larger size Cans, and thicker material alloys can be specified; small quantity orders to large run Can production, may be fabricated using traditional methods, including Spinning, CNC forming and TIG welding.
