The C36500 Low Lead Brass Tubes are available as hollow bars with heavy walls to be used in the making of parts requiring stiffness and machinability. C36500 is categorized as a leaded Muntz metal and it contains 58.0 to 61.0% copper, 0.25 to 0.7% lead and 0.25% maximum tin, with zinc as the remainder. The material features an alpha-beta brass composition, thus facilitating hot forging and fabrication of mechanical parts. Note that C36500 is not a common type of seamless brass tubing, thus care is required in ensuring that the product is ordered in the correct form, dimensions, and material specifications. USA Piping Solution supplies brass products for industrial applications, with material documentation and third-party inspection options available according to project requirements.

Frequently Asked Questions
What are C36500 low-lead brass tubes?
C36500 is a leaded Muntz metal brass alloy used in rod, bar, and hollow-bar forms for machining, forging, and industrial components.
What are the advantages of C36500 brass?
C36500 offers good hot-forging characteristics, moderate strength, and improved machinability compared with similar unleaded brass alloys.
Is C36500 brass considered lead-free?
No. C36500 typically contains 0.25% to 0.70% lead, so it is not considered lead-free.
What is the difference between C36500 and C36000 brass?
C36500 is a leaded Muntz metal with 58 to 61% copper and 0.25 to 0.7% lead. C36000 has 60 to 63% copper and 2.5 to 3.0% lead and is the free-cutting reference.
Is C36500 brass resistant to dezincification?
No. C36500 is classified as uninhibited brass and does not provide guaranteed resistance to dezincification.
Are C36500 brass tubes suitable for potable water applications?
Not automatically. Suitability depends on applicable drinking-water regulations, lead limits, product certification, and service conditions.
Is C36500 brass suitable for hot forging and precision machining?
Yes. C36500 offers good hot-forging characteristics and improved machinability, making it useful for producing industrial components.
