Formula: Cu 63/Zn 37
Form: Coil
Material: Brass
Commodity: Alloys
Brass Coil (Cu63/Zn37) is a copper-zinc alloy foil offered in Goodfellow's extensive range of metal foils. The material exhibits good ductility and corrosion resistance along with attractive golden color. Typical applications for brass foil include decorative parts, shims, spacers, and EMI shielding. The Cu63/Zn37 brass composition provides a versatile combination of formability, strength, and cost-effectiveness. As part of Goodfellow's metal foils inventory, brass coil enables rapid prototyping and development of parts requiring thin, flexible metallic sheets.
