C26000 70/30 Lead Free Brass Pipe Manufacturer

Q: What is C26000 70/30 brass used for?

C26000 70/30 brass is used for applications requiring good ductility, cold formability and corrosion resistance. Common applications include heat exchangers, condensers, plumbing components, hand pumps, general engineering components and products requiring deep drawing or forming. Its suitability for a specific service depends on the product form, temper, dimensions and applicable specification.

Q: Is C26000 the same as CuZn30 or CZ106?

C26000 is commonly cross-referenced with CuZn30 and CZ106 as designations for 70/30 brass. However, these designations belong to different standards and systems, so they should not automatically be treated as fully interchangeable. The applicable product standard, chemical requirements, dimensions, temper and certification should be checked before specifying one designation as an equivalent to another.

Q: Why is C26000 called lead-free brass?

C26000 is commonly described as a lead-free or low-lead brass because lead is not intentionally added as an alloying element. Its chemical composition permits lead up to a maximum of 0.07%, so the term does not mean that the material contains absolutely zero lead. For applications subject to specific lead-free regulations, the finished product must meet the applicable regulatory requirements.

Q: What is the difference between C26000 and C27000 brass?

C26000 is nominally a 70% copper and 30% zinc brass, while C27000 is nominally a 65% copper and 35% zinc brass. C26000 is generally valued for its high ductility and cold-forming capability, whereas C27000 provides a different balance of strength and formability. The actual mechanical properties depend on the product form and temper.

C26000 70/30 lead-free brass pipe is built from a copper-zinc alloy that holds the highest ductility found anywhere in the yellow brass series. This C26000 Cartridge Brass Pipe carries no intentional lead addition, which is exactly why buyers ask for it by name when a project calls for a clean, cold-formable brass with a fine surface finish. This pipe machines easily and cold forms even more easily, which is a combination most other brass grades cannot match at once. The seventy percent copper base gives C26000 70/30 lead free brass pipe a bright golden color along with real corrosion resistance in everyday plumbing and industrial water service, and that same copper content is what allows the alloy to be drawn, spun, and formed into shapes that a harder brass would simply crack under.

C26000 70/30 Lead Free Brass Pipe Equivalent Specifications

C26000 70/30 lead free brass pipe corresponds closely to several other national standards for the same base alloy. The table below lists one row per standard so the comparison stays clear. These designations help buyers sourcing C26000 Cartridge Brass Pipe match the required material designation with the applicable standard.

Standard	Designation
ASTM B135	C26000
BS 2871 Part 3	CZ106
EN 12451	CuZn30
DIN 1785	2.0265
NFA 51 102	CuZn30
JIS H3300	C2600
IS 4170 / 4413	CuZn30

Note: EN 12451 applies to the tube form of this alloy

C26000 70/30 Lead Free Brass Pipe Chemical Composition

The chemistry of C26000 70/30 lead free brass pipe is held within a tight band to guarantee the ductility and cold forming performance the grade is known for. The composition is shown below.

Element	Percentage
Copper (Cu)	68.5 to 71.5
Iron (Fe)	0.05 maximum
Lead (Pb)	0.07 maximum
Zinc (Zn)	Remainder (nominal 30.0)

The absence of any deliberate lead addition in C26000 70/30 lead free brass pipe is what earns the alloy its lead free classification, since the 0.07 percent maximum figure reflects trace impurity rather than a purposeful alloying addition.

C26000 70/30 Lead Free Brass Pipe Mechanical Properties

Mechanical properties for C26000 70/30 lead free brass pipe are stated below by temper, since the same alloy behaves very differently depending on how much cold work it has received. For ASTM B135 C26000 material, the supplied temper should therefore be considered when comparing mechanical performance.

Temper	Tensile Strength	Yield Strength	Elongation
Annealed (O)	330 MPa minimum	105 MPa minimum	45 percent minimum
Half Hard	385 MPa minimum	310 MPa minimum	20 percent minimum
Hard	455 MPa minimum	395 MPa minimum	8 percent minimum

C26000 70/30 lead free brass pipe in annealed temper offers the best combination of ductility for deep drawing and bending, while half-hard and hard tempers trade some of that ductility for higher strength where the pipe will not be reshaped after delivery.

Frequently Asked Questions

What is C26000 70/30 brass used for?

C26000 70/30 lead-free brass pipe is used across sugar factory condensers, heat exchangers, power generation plants, plumbing systems, hand pumps, and general engineering equipment, thanks to its ductility, machinability, and lead-free chemistry.

Is C26000 the same as CuZn30 or CZ106?

Yes. C26000, CuZn30, and CZ106 all describe the same base seventy-thirty brass alloy under the American, European, and British standard systems. C26000 70/30 lead-free brass pipe can generally be specified under any of these three names.

Why is C26000 called lead-free brass?

C26000 70/30 lead-free brass pipe carries no deliberate lead addition, unlike leaded brass grades where lead is added on purpose to improve machining speed. The 0.07 per cent maximum lead figure in the chemistry reflects trace impurities only, not an intentional alloying element.

What is the difference between C26000 and C27000 brass?

C26000 is the seventy-thirty grade with the highest ductility in the yellow brass series, while C27000 carries a higher zinc content of around sixty five thirty five and forms more readily in hot working. Buyers choose C26000 70/30 lead-free brass pipe when maximum cold formability is the priority.
