C330 Low Lead Brass Pipes are copper zinc alloy products for industrial use, suitable for moderate strength, they have machinability rate of 60, excellent cold formability. C330 is also known as C33000 and CDA 330. It is alloyed with 0.25-0.7% lead for easy machining. They are furnished in accordance with ASTM B135 which covers the specifications for seamless brass mechanical tubes. Pipe is a term used in trade. C330 is manufactured in seamless tube, to ASTM B135, so specify the outside diameter (OD), wall thickness and temper when ordering. USA Piping Solution has a large selection of brass piping for industrial use, with material test certificates and third party inspections provided upon request.

Frequently Asked Questions
What are C330 low lead brass pipes?
C330 low lead brass pipes are copper-zinc alloy products containing a controlled amount of lead to improve machinability and fabrication.
What are the advantages of C330 brass?
C330 brass offers good cold workability, moderate strength, and useful machinability for manufacturing industrial components.
Is C330 brass considered lead-free?
No. C330 brass contains lead, typically specified at approximately 0.25% to 0.70%, so it should not be considered lead-free.
What is the difference between C330 and C36000 brass?
C330 has 0.25% to 0.7% lead and a machinability rating of 60. C36000 has 2.5% to 3.0% lead and is the free-cutting reference at 100.
Is C330 brass resistant to corrosion?
C330 resists general atmospheric corrosion but is not a dezincification-resistant brass, so it is not suited to aggressive water or seawater. Check water chemistry, temperature, and service conditions.
Are C330 brass pipes suitable for potable water applications?
Not automatically. The alloy and finished product must meet applicable drinking-water lead limits and certification requirements.
How is C330 low lead brass fabricated and machined?
C330 brass can be cold-worked, drawn, bent, and machined using suitable tooling and process parameters, depending on its temper and product form.
ASTM B135 compliance. Material test certificates and third party inspections provided upon request.
