C22000 Red Brass pipe is an alloy made up of 90/10 copper zinc alloy (UNS C22000, EN CW501L), which contains 89.0 to 91.0% copper. It is also known as 90/10 commercial bronze. This is provided in seamless drawn tube, according to ASTM B135. It is highly ductile and can be cold worked easily. It is also resistant to atmospheric corrosion and therefore is suitable for decorative work, electrical components and forming applications. The use of C22000 includes Architectural trim, Electrical fittings, Builder’s hardware and precision forming applications. Its golden-red color makes it perfect for ornamental works. USA Piping Solution supplies C22000 tube with EN 10204 3.1 mill test certificates. Send your sizes to request a quote.

Frequently Asked Questions
What is a C22000 red brass pipe?
C22000 red brass pipe (or tube) is a 90/10 copper-zinc alloy (UNS C22000 / EN CW501L) containing 89.0 to 91.0% copper. It is known for its rich golden-red color, high ductility, and excellent corrosion resistance.
What is the composition of C22000?
C22000 consists of 89.0% to 91.0% Copper (Cu), 0.05% max Lead (Pb), 0.05% max Iron (Fe), and the remainder Zinc (Zn). Total Cu plus named elements must equal at least 99.8%.
Is C22000 the same as C23000 red brass?
No. C22000 is a 90/10 alloy (Commercial Bronze 90%). C23000 is an 85/15 alloy covered by ASTM B43 for red brass pipe. While both are called red brass in trade terminology, they differ in copper content and standard specifications.
Which standard covers C22000 tube?
Seamless C22000 brass tube is manufactured to ASTM B135 / B135M. ASTM B43 covers C23000 red brass pipe and does not apply to C22000.
What is the EN equivalent of C22000?
The European Standard equivalent of UNS C22000 is EN CW501L (also designated as CuZn10).
Is C22000 lead free?
Yes. C22000 has a maximum lead content of 0.05%, making it lead-free by composition (below the 0.25% limit). Potable water applications in North America still require finished-part NSF/ANSI 61 and 372 certification.
