C27450 DZR lead free brass hollow bars are bored yellow brass stock, used to create precision-machined fittings, connectors and fluid-handling parts. This is a low-lead copper-zinc alloy that has a maximum of 0.25% lead content and 60-65% copper content. With a machinability rating of about 70 versus 100 for C36000, it's more efficient for turning, boring and threading. But, dezincification resistance property is not intrinsic to C27450 and should be determined by appropriate testing and verified by documentation. USA Piping Solution has a stock of C27450 hollow bars that are cut to your requirements for your project and guaranteed to meet the tolerances required.

Frequently Asked Questions
1. What are C27450 DZR lead free brass hollow bars?
C27450 DZR lead free brass hollow bars are low-lead copper-zinc bored bars used to manufacture precision-machined fittings and industrial components.
2. Is C27450 brass lead-free?
C27450 contains a maximum of 0.25% lead. It meets the US lead-free definition for wetted surfaces when applicable requirements are satisfied.
3. Is C27450 brass resistant to dezincification?
No, not inherently. Its DZR performance should be verified through appropriate testing, such as ISO 6509-1.
4. What is the machinability rating of C27450 brass?
C27450 has a reported machinability rating of approximately 70, compared with 100 for free-machining brass C36000.
5. What is the difference between C27450 and C69300 Eco Brass?
C27450 is a low-lead copper-zinc brass, while C69300 is a silicon brass designed to provide intrinsic dezincification resistance with very low lead content.
