C48600 brass hollow bars are naval brass that is leaded in nature. They are made from an alloy of copper and zinc and are used in manufacturing wear parts that are used in marine and industrial applications. The composition of the material includes 59-62 percent copper, 1.0-2.5 percent lead, and additions of tin and arsenic, which help resist corrosion and dezincification. It has a machinability factor of about 70 compared to C36000, which has a value of 100. Applications of C48600 brass hollow bars include marine hardware, valve stems, pump parts, and industrial bushings. USA Piping Solution provides you with C48600 hollow bars in your required sizes.

Frequently Asked Questions
1. What are C48600 brass hollow bars?
C48600 brass hollow bars are leaded naval brass stock used to manufacture machined components requiring corrosion resistance and good machinability.
2. What is the machinability rating of C48600 brass?
C48600 has a reported machinability rating of approximately 70, compared with 100 for free-machining brass C36000.
3. Is C48600 brass lead-free?
No. C48600 contains approximately 1.0-2.5% lead, so it is a leaded brass alloy.
4. What is the difference between C48600 and C46400 naval brass?
C48600 contains lead to improve machinability, while C46400 generally has no intentional lead addition and offers good marine corrosion resistance.
5. Is C48600 brass resistant to dezincification?
CDA lists C48600 as a dezincification-resistant brass: arsenic (0.02 to 0.25%) inhibits dezincification and tin helps. Confirm with an ISO 6509-1 test where the application requires it.
6. Is C48600 brass suitable for marine applications?
Yes. Its tin and arsenic additions support corrosion resistance in seawater environments, making it suitable for marine hardware, valves, and pump components.
