Abstract

1,231,243. Fe-Mu alloys. INSTITUT DR ING REINHARD STRAUMANN A.G. May 10, 1968 [May 13, 1967], No.22286/68. Heading C7A. A frequency controlling element (e.g. spring, tuning fork or electro-mechanical filter), has a temperature co-efficient of the frequency determining modulus of elasticity in the range of plus or minus 10 x 10<SP>-5</SP>/‹C. and is formed from an alloy consisting of:- The control element may exhibit a frequency which is independent of temperature or may protect heavily loaded components against destructive self-resonance.
