Unlike a polymer coating, which will protect the string but may keep it from vibrating and resonating freely, electroplating enhances the string's vibration rather than deadening it. The strings are made from copper and zinc. The addition of zinc makes the strings less prone to corrosion. This is then combined with the electroplating, which will not wear off or break down but will actually become harder with time. These gold bronze Alchemy strings for acoustic guitars will give your sound a deep, balanced tone with rich harmonics, increased sustains and extra crisp high notes with great fullness and warmth.
