Under advanced production control, continuous casting in a high-frequency electric furnace, 19 processes of cold rolling, annealing twice, drawing with a diamond die, and skin-pass treatment are performed to use high-quality "high-purity silver wire" with not only high silver purity but also no gaps at the crystal grain boundaries.
The 0.2mm 5N pure silver single wire manufactured under such advanced production control is twisted into 7 strands to secure sufficient cross-sectional area (0.2sq). Conductor resistance is suppressed to the maximum extent.
The shell tip attached to the terminal uses highly springy phosphor bronze as the base material to improve adhesion with the contact pin. In addition, rhodium plating is used on the surface to prevent oxidation.
