Brass spooled wire (Cu63/Zn37) is a copper zinc alloy wire from Goodfellow's range of spoolable wires. This material offers both good ductility and strength, making it suitable for forming into springs or other shapes. Applications for brass wire include low-current electrical connections, screens and filters, jewelry, and musical instrument strings that produce a bright, resonant tone. With its versatile properties, brass wire finds use across industrial, commercial, and artistic fields.
