Product Overview

C34000 brass is a free-machining copper-zinc alloy containing controlled lead additions to improve machinability while maintaining good formability and corrosion resistance. It is manufactured to ASTM B36, ASTM B134, and related standards for decorative and industrial fabrication applications.

Produced through rolling, drawing, and precision forming processes, C34000 brass offers smooth machining characteristics, reliable dimensional stability, and an attractive golden appearance. Its balanced mechanical properties make it suitable for both decorative and functional components.

C34000 brass is extensively used in engraving plates, decorative trim, nameplates, architectural hardware, electrical fittings, and industrial fabricated parts where appearance and machinability are important. It is widely applied across construction, signage, electronics, and manufacturing industries.

C34000 Low Leaded Brass — FAQ

Practical FAQ on C34000 leaded brass composition, ASTM specs, properties and sourcing for screw-machine and forming parts.

C34000 is a wrought leaded brass with Cu 62.0–65.0%, Zn balance, Pb 0.8–1.5%, and Fe ≤0.15%. It balances moderate formability with enough lead for good machinability, sitting between low- and medium-leaded brass families.
ASTM B135 covers C34000 tube, rod and wire; it is supplied as drawn tube, rod and wire. Common tempers are O60, H01, H02 and H04, selected by the strength and ductility the part needs.
Ultimate tensile strength is roughly 340–650 MPa, yield 103–414 MPa, and elongation up to ~52% in soft temper. Conductivity is about 26% IACS and density ~8.5 g/cm³. Machinability rates around 60–70 (C36000 = 100).
No. With 0.8–1.5% lead it is outside RoHS limits and is not approved for drinking-water contact. It is used for screw-machine parts, couplings, nuts, rivets and general fittings where leaded machinability is acceptable.
Yes. Linsy supplies C34000 to ASTM in custom diameters, tempers and lengths with an MTR/MTC, SGS on request, and RoHS/REACH support. Lead time is typically 10–60 days, with low MOQ and a 1-hour quote response.
