Farmers Copper carries an extensive inventory of C36000 free-cutting brass round rod, hex rod, bar, and shapes of any specified cross-section manufactured to the ASTM B16 standard. Our C36000 brass has a lead substance of 2.5% to 3.7%, which allows the brass to be free-machined. This C36000 alloy is great for most processing techniques and is corrosion resistant.

According to ASTM International, this specification establishes the requirements for free-cutting brass rod, bar, wire, and shapes of any specified cross-section produced from Copper Alloy UNS No. C36000 suitable for high-speed screw machining applications and moderate thread rolling. The chemical composition, temper, tensile, Rockwell hardness, and shape requirements are detailed.

ASTM B16 Applications

Farmers Copper’s ASTM B16 free-cutting brass is utilized in high machining applications that require turning, drilling, and milling because of its machinability. C36000 free-cutting brass also has superior characteristics for soldering and brazing. This type of brass alloy is used for valve parts, faucet components, fasteners, plumbing fittings, and more.
