    Cu is the basis.
    According to GOST 23912-79, the permissible mass fraction of impurities (of all elements with a content of ≤) is calculated from the calculation for each 1% beryllium. As agreed by the manufacturer with the consumer, the ligature can be made with any mass fraction of beryllium from 4 to 11% inclusive, with deviations of ± 1.0%.
