The study was carried out on the variation of the mechanical properties due to the treatment by cold-drawing and precipitation hardening process on the specimens of beryllium-copper alloy wire. The specimens (diameter 1mmφ) were straightened after cold drawing. The results obtained are as follows. (1) The use of the straightener to straighten the beryllium-copper alloy wire has deteriorated the mechanical properties of the wire. (2) The cold-drawing has caused the beryllium-copper alloy wire an increase in tensile strength, yield strength, spring limit, hardness, and fatigue strength, but has caused it a decrease in modulas of elasticity, elongation, and number of torsion. (3) Precipitation treatment improves static properties such as spring limit, yield strength, tensile strength, and hardness considerably, but it improves fatigue strength but sightly. (4) Such static properties in the beryllium copper alloy wire as tensile strength, yield strength, spring limit and Vickers hardness have rectilineal correlation with one another whatever the manufacturing condition is. Therefore the measurement of any one of these properties will give a clue to that of any others.
