CZ112 naval brass pipe is an alloy made of copper, zinc and tin, and constructed following the British Standard BS 2874 specifications. It has been successfully used in marine and industrial applications ever since its inception, and for a simple reason: it serves a dual purpose of providing great toughness and appealing resistance to seawater corrosion. CZ112 naval brass pipe contains a significant amount of tin that makes it much more resistant to dezincification than regular alloy made of brass, and it also has no or very little lead, which makes its chemistry similar to that of the American C46400 grade, as compared to other leaded varieties of brass available on the market.
USA Piping Solution manufactures and supplies CZ112 naval brass pipe with full mill test documentation, dispatched from the United States.

Applications of CZ112 Naval Brass Pipe
CZ112 Naval Brass Pipe is selected for applications where strength, corrosion resistance and dependable performance are important.
- Marine Hardware: CZ112 naval brass is suitable for marine components and hardware exposed to moisture and demanding service environments
- Fasteners: strength and corrosion resistance support use in selected marine and industrial fasteners
- Engineering Components: the alloy can be used for machined and formed components where reliable mechanical performance is required
- Industrial Equipment: CZ112 naval brass pipe can be considered for industrial components requiring a durable copper zinc alloy
Frequently Asked Questions
What does the CZ112 designation mean under BS 2874?
CZ112 is the British Standard reference for a naval brass alloy with little to no intentional lead addition, closely matching the American C46400 grade in chemistry and mechanical behaviour.
Is CZ112 the same as C46400?
CZ112 and C46400 are treated as equivalent by most engineers, since both describe the same base naval brass chemistry under the British and American standard systems. CZ112 naval brass pipe can generally be substituted for C46400 material unless a project specifically requires British certification.
What is the difference between CZ112 and CW719R naval brass?
CZ112 carries little to no intentional lead, while CW719R (CuZn37Pb1Sn1) carries a controlled lead addition, roughly 0.4 to 1.0 per cent, that improves machinability. Choose CZ112 for a lower-lead naval brass and CW719R when faster machining matters more than minimising lead content.
Can CZ112 naval brass pipe be welded?
Yes. CZ112 naval brass pipe generally offers good weldability, though proper technique should be followed to avoid affecting the alloy's corrosion-resistant surface layer near the weld.
