| Low Brass |
A copper-zinc alloy with an alpha phase structure. The alloy has excellent cold-working properties and is generally resistant to dezincification and stress corrosion in most environments. Due to this combination of properties and its attractive colour, the alloy is widely used for decorative purposes and for miscellaneous formed and brazed components.
