COPPER-BASED ALLOY Russian patent published in 2004 - IPC

FIELD: non-iron metallurgy, in particular copper-based alloys with various content of alloy additions and impurity elements.

SUBSTANCE: claimed alloy contents (mass %): tin 0.0005-0.002; zinc 0.001-0.004; lead 0.001-0.004; antimony 0.0005-0.002; bismuth 0.0005-0.001, yttrium 0.005-0.02; oxygen 0.01-0.038; sulfur 0.001-0.005; and balance: copper, in proviso that total content of lead and bismuth is ≤0.0045 %, and that of oxygen and sulfur is ≤0,04. Invention may be used in atomic and thermonuclear energetic.

EFFECT: copper alloy with improved structure stability, physical, chemical and other properties, which provides high maintainability and endurance of thermonuclear reactor safety system.
