C33200 Brass Tube at a Glance
| Item | Specification |
| Alloy designation | UNS C33200 / CDA 332 |
| Product type | Seamless brass tube |
| Available shapes | Round, square and rectangular |
| Main standard | ASTM B135/B135M |
| Other references | ASME SB135 and AMS 4558 where applicable |
| Typical tempers | H55, H58, H80, O50 and O60, subject to size |
| Main advantage | Machinable brass tubing with excellent cold formability |
| Custom services | Cutting, drawing, straightening, polishing and inspection |
ASTM B135/B135M covers seamless round, rectangular and square brass tube. The standard identifies H55, H58 and H80 drawn tempers, together with O50 and O60 annealed tempers.
Chemical Composition
| Element | Composition |
| Copper, Cu | 65.0–68.0% |
| Lead, Pb | 1.5–2.5% |
| Iron, Fe | 0.07% max. |
| Zinc, Zn | Balance |
| Cu plus named elements | 99.6% min. |
C33200 contains intentionally added lead and must not be marketed as lead-free brass. For drinking-water or regulated applications, buyers should confirm the applicable local material and finished-product requirements before ordering.
Typical Mechanical and Physical Properties
| Property | Reference Value |
| Density | 8.53 g/cm³ |
| Electrical conductivity | 26% IACS |
| Machinability rating | 60 |
| H58 tensile strength | Approx. 448 MPa |
| H58 yield strength | Approx. 345 MPa |
| H58 elongation | Approx. 32% |
| H80 tensile strength | Approx. 517 MPa |
| H80 yield strength | Approx. 414 MPa |
| H80 elongation | Approx. 7% |
These are typical reference values rather than guaranteed design values. Final mechanical requirements depend on temper, tube dimensions and the governing purchase specification.
Why Choose C33200 Brass Tube?
Controlled lead content supports chip breaking during drilling, threading and turning. Unlike free-machining brass grades designed mainly for rods or bars, C33200 is specifically established for seamless tube, allowing manufacturers to combine tubular geometry with secondary machining.
The alloy offers excellent solderability, good brazing performance and excellent capacity for cold working. These characteristics support bending, flaring, piercing and machining when the correct temper is selected. Hot forming and several fusion-welding processes are generally less suitable.
Typical Applications
C33200 seamless brass tube is commonly used for:
Plumbing accessories and brass goods
Hydraulic control components
Pump cylinders and cylinder liners
Machined sleeves, bushes and spacers
Threaded fittings and connectors
Instrument and precision tubular components
Screw-machine products manufactured from tube
Custom OEM parts requiring soldering or bending
These applications benefit from the alloy's combination of machinability, moderate strength, cold formability, solderability and corrosion resistance.
C33200 Compared with Similar Brass Grades
| Grade | Main product form | Lead content | Selection guidance |
| C33000 | Seamless brass tube | 0.25–0.70% | Lower-lead tube option with a similar copper range |
| C33200 | Seamless brass tube | 1.5–2.5% | Suitable when tube machining and cold forming are both required |
| CW606N / C35300 family | Mainly rod, bar and profiles | Approx. 1.7–2.8% | Similar lead level but different copper range, standards and properties |
C33000 and C33200 are both recognized tube alloys, but they have different lead limits. CW606N is commonly supplied under European rod and bar standards and should not be listed as an automatic equivalent to C33200. Any substitution must be approved against the drawing, chemical limits, temper, product form and end-use requirements.
Manufacturing and Quality Control
Dongmeng Group controls C33200 tube production from material verification through final export packing. Inspection can include:
Spectrometer verification of Cu, Pb, Fe and Zn
Outside dimension and wall-thickness measurement
Straightness, ovality and surface-quality inspection
Tensile and hardness testing when specified
Eddy-current, hydrostatic or pneumatic testing when required
Lot identification and material test documentation
Third-party inspection according to the purchase order
ASTM B135/B135M includes mechanical and nondestructive testing requirements such as tensile, hardness, expansion, eddy-current, hydrostatic and pneumatic testing where applicable.
Tubes can be protected with suitable wrapping, bundles, wooden cases or pallets to reduce impact, moisture and surface damage during international transportation.
Frequently Asked Questions
Is C33200 a low-lead or lead-free brass?
No. C33200 is classified as high-leaded brass tube and contains 1.5%–2.5% lead.
What is the main standard for C33200?
ASTM B135/B135M is the primary specification for seamless round, square and rectangular C33200 brass tube.
Which temper is suitable for bending?
H55 light-drawn or an annealed temper may be considered when bending performance is important. Final temper selection should consider tube dimensions, wall thickness, bend radius and required strength.
Is CW606N equivalent to C33200?
Not directly. CW606N has different copper limits and is mainly associated with rod, bar and profile standards. Cross-standard substitution requires engineering approval.
