LONDONDERRY, NH— The MμShield Company, Inc, a leading supplier of high permeability magnetic shielding, announced that it has partnered with The AT Wall Company, of Warwick, Rhode Island to develop MμShield high permeability magnetic shielding seamless tubing. The product is a result of extensive research and development, and is superior for applications that require precision machined magnetic shield components or where long lengths of small diameter tubing are needed. Typical applications include aircraft instrumentation, medical and surgical equipment, oil exploration, and imaging equipment.

"AT Wall was able to use its deep drawing capabilities to take plate supplied by MμShield, cup it and then draw it into tubing. Being able to supply the product in tubing form greatly reduces the cost of manufacturing for MμShield and its customers as it reduces scrap." said Donna Parker, AT Wall’s director of sales.

The MμShield seamless tubing’s shielding capability is 20-30 percent better than a formed and welded product, depending on the welding method used. The seamless tube offers complete shielding homogeneity and attenuation uniformity throughout the walls and length of the tube. The MμShield product can also decrease machining times significantly and save on material costs, important for applications with tight tolerances on machined details and roundness.

When compared to machining product from solid bar or fabricated cylinders, the MμShield seamless tubing is a sure choice. It can hold both outside and inside diameters to .002” along with wall thicknesses within .002”. MμShield seamless tubing is available with wall thicknesses from .005” through .250”. Sizes range from outside diameters of .080” to 2.625” Lengths are up to 20'. MμShield seamless tubing meets the standards of ASTM A753-08, standard specification for wrought nickel-iron soft magnetic alloys.

A.T. Wall Company is a subsidiary of ATW Companies, which also includes Judson A. Smith Company, located in Boyertown, PA, and Parmatech Corporation, located in Petaluma, CA.
