C34200 High Leaded Brass — FAQ

Practical FAQ on C34200 leaded brass composition, ASTM specs, properties and sourcing for high-machinability parts.

C34200 is a wrought high-leaded brass with Cu 62.0–65.0%, Zn balance, Pb 1.5–2.5%, and Fe ≤0.15%. The higher lead content maximizes machinability versus lower-leaded grades.
ASTM B135 covers C34200 tube, rod and wire; it is also available as flat products and rod. Tempers include O60, H01, H02, H04 and H06.
Ultimate tensile strength runs 338–586 MPa, yield 117–427 MPa, and elongation 3–52% depending on temper. Electrical conductivity is about 26% IACS and machinability rates 90 (C36000 = 100).
No. Pb 1.5–2.5% places it outside RoHS limits and it is not approved for potable-water contact. Typical uses are clock plates, gears, nuts, screw-machine parts and fittings where maximum machinability is needed.
Linsy supplies C34200 to ASTM with custom sizes and tempers, an MTR/MTC, SGS on request, and RoHS/REACH support. Typical lead time is 10–60 days with low MOQ and a 1-hour quoting response.
