Brass tubes combine a warm gold finish with excellent formability, good corrosion resistance and easy machining and joining. They appear in plumbing, lighting, musical instruments, radiators, instrumentation, furniture and architectural trim. As a brass tubes manufacturer in India, we help buyers choose among the alloys, tempers and standards. Here is what to know before you order.
Brass is an alloy of copper and zinc. Raising zinc content increases strength and lowers cost but reduces corrosion resistance and cold ductility. Small additions of lead, tin, aluminium or arsenic tailor the alloy for machining, seawater or inhibited service. Seamless brass tubes are produced by extruding cast billets and drawing them to final size.
| Alloy | UNS / EN | Cu / Zn | Characteristics | Typical use |
|---|---|---|---|---|
| Commercial bronze | C22000 | 90 / 10 | Colour like bronze, excellent cold working | Jewellery, decorative, fasteners |
| Red brass | C23000 | 85 / 15 | Good corrosion resistance, very formable | Plumbing, pipe nipples, radiators |
| Cartridge brass | C26000 / CW505L | 70 / 30 | Best combination of strength and ductility | Deep drawing, general tubes, ammunition cases |
| Yellow brass | C27200 / CW507L | 63 / 37 | Strong, economical | General engineering, fittings |
| Admiralty brass | C44300 | 71 / 28 / 1 Sn | Inhibited against dezincification | Condenser and heat exchanger tubes |
| Naval brass | C46400 | 60 / 39 / 1 Sn | Seawater resistant | Marine hardware and tubes |
Besides round tube, brass tubes are available as square, rectangular and hexagonal sections for architectural railing, furniture, instrument housings and fittings. Round brass tube is commonly supplied from about 6 mm to 150 mm OD with walls from 0.5 mm upwards, in lengths of 3 m to 6 m and cut to order. Precision tube with tight OD and wall tolerances is used for instrumentation, nozzles and telescopic assemblies.
Brass bends and flares easily in the soft temper and can be silver brazed, soft soldered, threaded or press formed. Surface finishes include natural mill finish, polished, satin, lacquered and electroplated chrome or nickel. For potable water systems, check lead and dezincification requirements of the local regulations.
If your system is under pressure with a standard thread, see our guide to brass pipes; for cooling-water duty, see brass condenser tubes.
Melta Alloys manufactures seamless brass tubes, including Naval and Admiralty brass, at Umbergaon, Gujarat, using extrusion presses and precision tube mills. We hold tight control over composition with spectrometer analysis, test hardness and pressure integrity in-house, and export to 20+ countries with mill test certificates.

Copper tube is pure copper (99.9%); brass tube is a copper-zinc alloy. Brass is stronger and cheaper but less suitable for fluids that cause dezincification unless it is an inhibited alloy.
C26000 (cartridge brass, 70/30) is the best all-round grade for formable tubes; C23000 red brass is preferred for plumbing and C44300 for cooling-water heat exchangers.
