This document provides basic and fundamental information on the magneticpermeability and electrical conductivity characteristics of metals and alloys.The handbook is not intend

5、ed to be referenced in purchase specificationsexcept for informational purposes, nor shall it supersede any specificationrequirements.k. Every effort has been made to reflect the latest information on themagnetic permeability and electrical conductivity characteristics of themetals and alloys listed

6、 It is the intent to review this handbookperiodically to ensure its completeness and accuracy.5. This handbook provides design engineers and equipment a75anufacturers withgeneral information on magneci.c permeability and electrical conductivitycharacteristics of metals and alloys used in the manufa

7、cture of equipment chatwill be used in maenetic sensitive areas aboard Naval shiDs The a75etals andalloys included are primarily those having low (less than 2.O) relativemagnetic permeability in the mill annealed condicion. However, ocher metalsand alloys with higher magnetic permeability are also i

8、ncluded because theiruse in equipment is dictated by consideration of other properties that are notalways available in low magnetic permeability materials6. The values given herein should be considered as “typical” They areintended to show the relative effect of cold-working operations on thecharact

9、eristics cited.7. The numeric values for properties listed in this handbook, that werederived from specifications , standards , handbooks , a“d ocher publications ,reflect the values in issues in effect on the date of the approval of thishandbook. Because of che revisions of or amendments to these d
