Abstract  The erratic magnetic properties exhibited by the copper-beryllium alloy system have limited its use for ultra-low permeability applications. This work examines the factors controlling the magnetic properties and isolates the beta phase which, in combination with small quantities of iron, present as an impurity, is the major cause of the erratic behaviour. Methods of eliminating the beta phase are recommended and an improved non-magnetic alloy, based on beryllium-copper, has been developed. This shows mechanical properties of 80 tsi with 10% elongation whilst maintaining a low magnetic permeability of 1.0000 to 1.0002.。。。。。。。。。。。
