The pipe made of EN 12451 CuZn28Sn1As brass alloy is composed of copper and zinc and has very small quantities of tin, resulting in great resistance to dezincification than standard brass has. EN 12451 CuZn28Sn1As brass pipe has European standard designations of the copper alloy family and can also be called CW706R, therefore, if the buyer looks for this alloy with the help of either name, one shall understand that it is the same pipe. EN 12451 CuZn28Sn1As brass pipe is resistant to seawater, rivers, and steam for years without changing its surface. USA Piping Solution supplies EN 12451 CuZn28Sn1As Admiralty brass pipe with complete mill test documentation and reliable dispatch from the United States.

Frequently Asked Questions
What does the EN 12451 standard designate for Admiralty Brass?
EN 12451 is the European standard reference for seamless copper alloy tube used in heat exchangers, and CuZn28Sn1As is the specific designation within that standard for admiralty brass. When a specification calls for EN 12451 CuZn28Sn1As admiralty brass pipe, it is asking for tube produced and tested against this specific European chemistry and property range, as opposed to the American, British, French or Japanese equivalents of the same base alloy.
Is EN 12451 CuZn28Sn1As the same as ASTM C44300?
EN 12451 CuZn28Sn1As and ASTM C44300 describe the same base admiralty brass alloy and are treated as equivalent by most engineers. EN 12451 CuZn28Sn1As admiralty brass pipe can generally be substituted for C44300 material unless a project specifically requires European certification.
What does the CW706R material number mean?
CW706R is the material number assigned to EN 12451 CuZn28Sn1As admiralty brass pipe under the European numbering system. It refers to the exact same alloy as CuZn28Sn1As, so a buyer will see both terms used interchangeably on drawings and purchase orders for this material.
What is the difference between EN 12451 CuZn28Sn1As and NFA 51 102 CuZn29Sn1?
EN 12451 CuZn28Sn1As admiralty brass pipe and NFA 51 102 CuZn29Sn1 admiralty brass pipe describe the same base alloy family under two different national standards, European and French. The chemistry and mechanical properties are very close between the two, and most engineers treat them as interchangeable unless a project specifically calls for one standard over the other.
