Brass Parts India is a specialized manufacturer and global exporter of C36000 Brass Machined Parts and C36000 CNC Turned Parts — supplying US OEMs, distributors, electrical manufacturers, plumbing product companies, and industrial buyers with consistent, high-quality free-machining brass components at competitive factory-direct prices. C36000 (Free-Cutting Brass) is the most widely used brass alloy in North America and is the recognized benchmark for machinability in non-ferrous metals globally.
What is C36000 Brass?
C36000 — also designated as UNS C36000, ASTM B16, and commonly called “Free-Cutting Brass” or “Architectural Bronze” — is a copper-zinc-lead alloy containing 60–63% copper, 35.5–38.5% zinc, and 2.5–3.7% lead. The lead particles distributed throughout the matrix act as microscopic chip-breakers and lubricants during cutting, giving C36000 a machinability rating of 100% — the highest of any copper alloy and the standard against which all other metals are measured. This means extremely high cutting speeds (up to 300 m/min on CNC lathes), minimal tool wear, excellent surface finish, and the lowest machining cost per part.

Frequently Asked Questions – C36000 Brass
Q1: What does C36000 brass stand for?
A: C36000 is the UNS (Unified Numbering System) designation for free-cutting brass — the most machinable standard brass alloy. The “C” prefix indicates a copper-based alloy, “3” indicates a brasses group (copper-zinc with other elements), and the full number identifies the specific composition. It is equivalent to CZ121/CW614N in Europe.
Q2: Is C36000 suitable for potable water fittings in the USA?
A: Standard C36000 is NOT compliant with California AB1953 or NSF 372 “lead-free” requirements (which mandate ≤0.25% weighted average lead). For US potable water applications we recommend our low-lead alternatives: C69300 (Eco Brass) or C87850 (silicon brass). We manufacture and export these lead-free alternatives as well — please ask about our lead-free plumbing range.
Q3: What thread forms can you produce on C36000 parts?
A: We can cut virtually any thread form: Metric (M1.6–M100), UNC, UNF, BSP (BSPP/BSPT), NPT, NPTF, ACME, trapezoidal, and custom thread profiles. Right-hand and left-hand threads available.
Q4: What is your quality inspection process?
A: 100% dimensional check on first-off and last-off pieces each production run. AQL 1.0/2.5 sampling on bulk output. CMM inspection for complex parts. Full PPAP documentation (Level 1–5) available for automotive and critical applications. All shipped with certificate of conformance.
Q5: Do you offer sample parts before committing to full production?
A: Yes. We offer pre-production samples (typically 10–50 pieces) for customer approval before full production release. Sample cost and lead time approximately 2–3 weeks. Sample cost credited against the production order.
