C24000 Red Brass Pipe is an 80/20 zinc-copper alloy, also called Low Brass 80%. The alloy has excellent formability properties and high ductility, which make it ideal for use in making parts of intricate shapes having reddish golden coloration, with atmospheric corrosion resistance. C24000 pipe can be used in architectural trimming, decorative hardware, flexible metal hose, electrical fittings, and musical instrument components. The formability of the alloy makes it bendable and drawable through various other cold working processes. C24000 is not available in ASTM B135 or ASTM B43, and thus it is supplied as per mill or customer specification or EN 12449. USA Piping Solution supplies C24000 tube with EN 10204 3.1 mill test certificates. Send your sizes to request a quote.

Frequently Asked Questions
What is C24000 red brass pipe?
C24000 red brass pipe (or low brass tube) is an 80/20 copper-zinc alloy (UNS C24000 / EN CW503L) containing 78.5 to 81.5% copper. It is recognized for its golden-red color, exceptional cold ductility, and corrosion resistance.
What is the composition of C24000?
C24000 consists of 78.5% to 81.5% Copper (Cu), 0.05% max Lead (Pb), 0.05% max Iron (Fe), and remainder Zinc (Zn).
Is C24000 the same as C23000 red brass?
No. C24000 is an 80/20 alloy (Low Brass 80%), whereas C23000 is an 85/15 alloy (Red Brass 85%). Standard red brass pipe under ASTM B43 is specifically C23000.
What is the EN equivalent of C24000?
The European Standard equivalent for UNS C24000 is EN CW503L (also designated as CuZn20). The legacy British specification is BS CZ103.
Which standard covers C24000 tube?
C24000 is not listed in ASTM B135 or ASTM B43. Seamless C24000 tubing is manufactured to custom customer specifications, mill standards, or EN 12449.
Is C24000 lead free?
Yes. C24000 restricts lead to 0.05% maximum, making it lead-free by composition (below the 0.25% limit). Finished potable-water products in the US need NSF/ANSI 61 and 372 certification.
