CZ108 CW508L Basis Brass is a 37% zinc containing brass commonly referred to as basis brass. Predominantly an alpha brass it is one of the most popular sheet and plate grades due to its hot and cold working capabilities.
CW508L / CZ108 is often used for general purpose applications and forming operations when very good bending properties are required. It also offers a very good general corrosion resistance in many natural atmospheres, a reasonable machinability and good cold heading properties. brass edging copper strip sheet, View brass strip sheet
