Material: Gilding Metal
Commodity: Alloys
Temper:
As Drawn
Gilding Metal Alloy Spooled Wire (Cu85/Zn15) is a copper-zinc alloy wire prized for its exceptional ductility, corrosion resistance, and excellent cold-working properties. With 85% copper and 15% zinc, it offers a unique combination of conductivity and formability, making it ideal for precision forming and decorative applications. Industries use this alloy in electrical connectors, ammunition casings, and fine metalwork where consistent mechanical performance is essential. Specific applications include precision wire for electrical discharge machining (EDM), coiled feedstock for intricate stamping operations, and decorative elements requiring high polish retention. In research and manufacturing, this spooled wire serves as a key material for studying brass deformation mechanics, optimizing EDM wire performance, and developing corrosion-resistant alloy coatings. Its balance of strength, conductivity, and workability ensures its continued value in both scientific advancements and high-performance industrial uses.
