Brass is a copper alloy in which the main alloying element is zinc. The generic term “brass” covers a wide range of materials suitable for many different types of applications.
Characteristics of Brass
Good corrosion resistance
Good machinability & formability
Toughness at all temperatures
Good spark resistance
Low magnetic permeability
Contain 10 - 20% zinc and are used for architectural metal work, paper making, jewellery strip and applications requiring suitability for brazing and enameling.
Contain 30% zinc, have the maximum ductility of the copper-zinc range and are used for deep drawing.
Contains 36% zinc and is the most usual composition used for brass sheet.
Free machining brass
Contains 39% zinc and is the standard alloy against which machinability of other alloys has been judged.
