CW501L / CZ101 is an alpha brass consisting of approximately 90% copper and 10% zinc. Also known as Gilding Metal the CW501L / CZ101 is primarily offered as a sheet grade due to its excellent cold working properties.

The make-up of CW501L / CZ101 means it is not generally susceptible to dezincification or stress corrosion and due to its formability and its attractive rich golden colour it is widely used for architectural and decorative applications. It is also readily enamelled, soldered and brazed.
