CZ114 Naval Brass Pipe | BS 2874 High Tensile Brass

Q: What is the CZ114 Naval Brass Pipe?

CZ114 is a high tensile brass grade specified under BS 2874 and commonly associated with the European designation CW721R. It is a duplex alpha beta copper zinc alloy containing controlled additions of aluminium, iron, manganese, tin and lead. These alloying additions provide high strength, good corrosion resistance, good machinability and very good hot working characteristics.

Q: What is the chemical composition of CZ114?

The BS 2874 CZ114 composition is approximately 57.0 to 59.0% copper, 0.8 to 1.8% manganese, 0.8 to 1.6% aluminium, 0.2 to 1.2% iron, 0.8 to 1.8% lead and 0.2 to 1.0% tin, with zinc as the remainder. The exact limits should be confirmed against the applicable edition of the governing material specification.

Q: What is the CZ114 equivalent grade?

CZ114 is commonly cross referenced with CW721R and the European alloy designation CuZn40Mn1Pb1AlFeSn. Some commercial sources also associate CZ114 with UNS C67500, but equivalence should be verified against the applicable product form and material specification before substitution.

Q: Is CZ114 the same as CZ115?

No. CZ114 and CZ115 are separate high tensile brass grades. CZ114 is associated with CW721R and contains aluminium, iron, manganese, tin and lead, while CZ115 is associated with CW722R and has a different alloy composition. The two grades should not be treated as interchangeable without checking the applicable specification and service requirements.

CZ114 Naval Brass Pipe is a type of brass alloy that is characterized by high resistance, strength, and stability while working hot. This alloy consists of numerous metals such as zinc, lead, copper, tin, manganese, iron, and aluminum and has a duplex structure comprising alpha and beta phases. CZ114 Naval Brass Pipe has a wide variety of engineering applications, for example, in gas valves, fastening items, pumps and other components. USA Piping Solution supplies CZ114 Naval Brass Pipe in the correct dimensions and quantities to meet customer specification requirements.

What is CZ114 high tensile brass?

CZ114 high tensile brass is a duplex alpha beta brass grade specified under BS 2874. Its aluminium, iron, and manganese additions increase strength compared with conventional brass grades.

What is the chemical composition of CZ114?

The CZ114 chemical composition includes 56.50 to 58.50 per cent copper, 0.20 to 0.80 per cent tin, 0.50 to 1.50 per cent lead, 0.30 to 1.00 per cent iron, up to 1.50 per cent aluminium, and 0.50 to 2.00 per cent manganese, with zinc as the remainder.

What is the CZ114 equivalent grade?

The principal European equivalent designation for CZ114 is CW721R. The alloy is also associated with CuZn39AlFeMn in European material references.

Is CZ114 the same as CW721R?

CZ114 and CW721R are commonly used as the British and European designations for the same high tensile brass grade. The applicable product standard should still be checked before substitution.

Is CZ114 the same as CZ115?

No. CZ115 is a separate high tensile brass grade associated with CW722R. Its restricted aluminium content distinguishes it from CZ114 and can make it more suitable for certain joining operations. See ourCZ134 Naval Brass Pipe page for another distinct naval brass grade sometimes confused with this one.
