CuZn37Pb1Sn1 Naval Brass (CW719R) Manufacturer

Q: Is CuZn37Pb1Sn1 the same as CW719R?

No. CuZn37Pb1Sn1 is associated with CW714R, not CW719R. CW719R corresponds to CuZn39Sn1 and is commonly cross referenced with CuZn38Sn1 and UNS C46400 naval brass. Therefore, CuZn37Pb1Sn1 and CW719R should not be treated as the same material designation.

Q: Does CuZn37Pb1Sn1 naval brass contain arsenic?

Arsenic is not a defining alloying element in the CuZn37Pb1Sn1 designation. The designation identifies a copper zinc alloy containing nominal additions of lead and tin. The exact permitted impurity and residual element limits depend on the applicable European product standard, so the material certificate should be checked for the supplied product.

Q: Where can I find full chemistry and mechanical properties for CuZn37Pb1Sn1?

The applicable European product standard should be used for the definitive chemical composition and mechanical requirements of CuZn37Pb1Sn1. The grade is associated with CW714R, and its mechanical properties vary with product form, size and delivery condition. A material datasheet or mill test certificate should therefore be checked for the specific CuZn37Pb1Sn1 product supplied.

Q: What is the difference between CuZn37Pb1Sn1 and CZ112 naval brass?

CuZn37Pb1Sn1 and CZ112 are different copper alloy designations. CuZn37Pb1Sn1 is associated with CW714R and contains controlled lead and tin additions. CZ112 is associated with CW712R and is a naval brass grade containing approximately 61 to 63% copper with tin as a principal alloying addition and controlled lead depending on the applicable product standard. They should not be treated as interchangeable grades.

CuZn37Pb1Sn1 naval brass pipe is a copper-zinc alloy containing controlled additions of tin and lead. It is identified by the European material number CW719R. The addition of tin improves resistance to corrosion in marine and water environments, while the controlled lead content improves machinability for components that require efficient cutting, turning and machining. CuZn37Pb1Sn1 naval brass is therefore used for marine hardware, valve components, pumps, screw machine products and general engineering applications where corrosion resistance and machinability are both important.

Frequently Asked Questions

Is CuZn37Pb1Sn1 the same as CW719R?

Yes. CuZn37Pb1Sn1 is the European chemical symbol, and CW719R is the European material number for the exact same naval brass alloy. Both names refer to one identical material stocked under the same product line.

Does CuZn37Pb1Sn1 naval brass contain arsenic?

No. CuZn37Pb1Sn1 naval brass does not contain arsenic. Arsenic addition is a defining feature of admiralty brass, a separate alloy family, not this leaded, tin-bearing naval brass grade.

Where can I find full chemistry and mechanical properties for this grade?

Full chemistry, physical properties, mechanical properties by temper, and pipe dimensions for CuZn37Pb1Sn1 naval brass are published on our CW719R naval brass pipe page, since the two names describe the same material.

What is the difference between CuZn37Pb1Sn1 and CZ112 naval brass?

CuZn37Pb1Sn1 carries a controlled lead addition, roughly 0.4 to 1.0 per cent, that improves machinability, while CZ112 carries little to no intentional lead and is closer in chemistry to the American C46400 grade.
