The copper-zinc alloy used in making BS 2871 Part 3 CZ 111 admiralty brass includes just a tiny amount of tin, which makes the tube highly resistant to dezincification. The British standard definition of this type of alloy makes BS 2871 Part 3 CZ 111 immediately recognizable to users of the standard. Due to the fixed chemical composition and hardness used in the production of this alloy-type tubes, users can reliably expect the same successful attributes that this alloy has. The tube is also resistant to both seawater and freshwater, which is one of the reasons it is currently widely used in numerous industrial applications. USA Piping Solution supplies BS 2871 Part 3 CZ 111 Admiralty brass tubes with complete mill test documentation and reliable dispatch from the United States.

Frequently Asked Questions
What does the BS 2871 Part 3 standard designate for Admiralty Brass?
BS 2871 Part 3 is the British national standard reference for copper alloy tube, and CZ111 is the specific designation within that standard for admiralty brass. When a specification calls for BS 2871 Part 3 CZ 111 admiralty brass tubes, it is asking for tubes produced and tested against this specific British chemistry and property range, as opposed to the American, French, European, or Japanese equivalents of the same base alloy.
Is BS 2871 Part 3 CZ111 the same as ASTM C44300?
BS 2871 Part 3 CZ111 and ASTM C44300 describe the same base Admiralty brass alloy and are treated as equivalent by most engineers. BS 2871 Part 3 CZ 111 Admiralty brass tubes can generally be substituted for C44300 material unless a project specifically requires British certification.
What is the difference between half-hard, quarter-hard, and soft-tempered?
Half-hard BS 2871 Part 3 CZ 111 Admiralty brass tubes offer higher strength for straight-run applications, while quarter-hard and soft temper offer greater ductility for tube that will be expanded, bent, or coiled during installation. The right choice depends on how the tube will be handled after it arrives on site.
What end finishes are available for BS 2871 CZ111 Admiralty brass tubes?
BS 2871 Part 3 CZ 111 Admiralty brass tubes are available with plain, beveled or threaded ends. USA Piping Solution can confirm which end finish suits your installation method at the time of the quote.
