90/10 Red Brass Tubes are produced from a high-copper alloy that is made with about 90% copper and 10% zinc, known as UNS C22000 and Commercial Bronze 90%. The tubes can be used for applications which require detailed shapes, golden-red colourful tube surface, high ductility and good cold forming ability and can withstand atmospheric corrosion. These applications include architectural trim, decorative hardware, electrical parts, watch parts and deep-drawn products. The alloy is easily bent, spun, flattened and stamped. Seamless tube is available to ASTM B135/B135M. USA Piping Solution offers 90/10 red brass tube that comes in the form of EN 10204 3.1 mill test certificates. Please email your sizes and get a quote.

Frequently Asked Questions
What are 90/10 red brass tubes?
90/10 red brass tubes are seamless copper-zinc alloy tubes (UNS C22000 / EN CW501L) composed of 90% copper and 10% zinc. They offer a rich golden-red finish, high cold formability, and good corrosion resistance.
Is 90/10 red brass the same as C22000?
Yes. UNS C22000 is the official designation for 90/10 red brass, also known as Commercial Bronze 90% and EN CW501L.
Which standard covers 90/10 red brass tube?
Seamless 90/10 red brass tubing is manufactured and certified to ASTM B135 / B135M. Standard red brass pipe under ASTM B43 covers C23000 (85/15) only.
What tempers are available?
Per ASTM B135, 90/10 tube is available in annealed tempers (O50, O60) for bending and expanding, and drawn tempers (H55, H58, H80) for rigid structural uses.
Is 90/10 red brass machinable?
90/10 red brass has a machinability rating of 30% relative to Free-Cutting Brass (C36000 = 100%). It is selected primarily for cold forming, swaging, and bending rather than high-speed machining.
Is 90/10 red brass lead free?
Yes. 90/10 red brass limits lead content to 0.05% maximum, making it a lead-free composition (below the 0.25% maximum requirement).
Material documentation and third-party inspection options available according to project requirements.
