Five C36000 brass mechanical parts — nuts, threaded bodies, bushings, sleeves, and hex turned parts. C36000's excellent machinability (rating 100) produces the cleanest thread form of any metal — self-lubricating thread quality due to the lead content enables smooth mating cycles over thousands of engagement repetitions without galling, which is a key reason brass is preferred over stainless for connector and instrument thread interfaces.

Complete range of C36000 brass mechanical parts: custom hex and round nuts (thread 4H/6H, across-flats h9, go/no-go inspected), precision threaded bodies (thread 6g/6H, optical profile inspection, Ra ≤0.4μm), brass bushings (H7 bore, OD/ID concentricity ≤0.005mm, Ra ≤0.4μm), brass sleeves and spacers (H7/h7 bore-OD, length tolerance ±0.01mm), and hex turned parts — standoffs, inserts, spacers (hex AF h9, thread 4H/6H, M2–M24). All thread features inspected with calibrated go/no-go gauges. C36000 thread self-lubricating quality: the lead particles in C36000 act as solid lubricant at the thread flank surface during engagement, producing smoother, more consistent torque-to-clamp-load relationships than bare stainless or carbon steel threads — the primary reason brass is specified for instrument, scientific, and connector threaded interfaces requiring consistent mating force.

Why Brass C36000 Parts Demand
No Compromise on Thread & Finish

🏆
Machinability 100 — The Reference Standard
C36000 machinability rating of 100 is the reference against which all other metals are measured — it is the most machinable metal commercially available. Cuts 3× faster than 12L14 steel, 5× faster than SS303, 2× faster than aluminium 6061. Produces Ra ≤0.4μm surface finish off the lathe. This translates to: lower cost for the same tolerance, shorter lead times, and more consistent dimensional results across large production batches.
Rating 100Best surface finish
🔩
Thread Quality — Self-Lubricating Lead Inclusions
The lead in C36000 acts as a solid lubricant at thread flank surfaces during engagement — producing smoother torque-to-clamp-load relationships than bare stainless or carbon steel threads. This is why brass is specified for instrument, scientific equipment, and connector threads requiring consistent mating force over thousands of cycles without galling. All threads inspected with calibrated go/no-go gauges. Optical comparator profile inspection for precision instrument threads.

DZR Brass — Dezincification Resistance
DZR (CW602N, ~0.05% As) resists dezincification in hot chlorinated water — required for UK WRAS approval, EU potable water compliance, and Australian AS/NZS 3520. Standard C36000 dezincifies in these conditions: zinc is selectively leached leaving a porous copper structure with no mechanical strength. We specify DZR for all potable water applications without needing to be asked — we advise on grade selection at DFM review.

Swiss-Type CNC — Ø0.5mm L/D 20:1
Swiss-type (sliding headstock) CNC lathes for contact pins and instrument threads at Ø0.5–Ø8mm with L/D > 10:1 — where conventional turning produces OD taper from workpiece deflection. C36000's machinability rating of 100 makes it the ideal material for Swiss-type turning at maximum cutting parameters: highest surface finish with minimum tool pressure and deflection. Contact pin OD h6, cylindricity ≤0.003mm, Ra ≤0.2μm — achievable in one Swiss-type CNC setup.

Gold Plating — XRF Verified for Connectors
Gold plating (0.1–0.5μm over 2–5μm nickel) XRF thickness-measured for signal connector contact pins and RF connector bodies on critical connector orders. A nominal 0.2μm gold specification can deliver 0.05μm actual thickness from process variation — insufficient to prevent nickel oxide formation at the contact interface. We measure and document the plating thickness on critical orders.

Plating & Finishing for Pièces en laiton

Brass plating selection is driven by the application's corrosion, solderability, and contact resistance requirements.

🔘
Nickel Plating (3–10μm)
Most common for brass parts. Corrosion resistance, harder than bare brass, solderable, and good adhesion base for subsequent gold or chrome. Bright or satin finish. Required for connector shells, valve bodies, and fittings in industrial environments. 3μm for indoor; 10μm for outdoor or humid.
Corps de valveConnector shells
🥈
Tin Plating (3–10μm)
For brass terminal bodies and connector pins requiring solderability — RoHS compliant alternative to lead-based solder coating. Prevents brass oxide formation that impedes soldering. Bright tin or matte tin. Applied over nickel strike for better adhesion and corrosion performance.
TerminalsPCB pins
🥇
Gold Flash (0.1–0.5μm / Ni)
Gold over 2–5μm nickel barrier for signal connector contact pins and precision terminals requiring minimum and stable contact resistance. Gold prevents nickel oxide at contact interface. XRF verified for critical connector orders. Standard for data and signal connectors in electronic instruments.

Notre Avantage

Pourquoi les ingénieurs spécifient nos Pièces en laiton

DZR
DZR Specified — Not Left to Chance
We specify DZR (CW602N) for potable water fitting applications without needing to be asked. Most suppliers assume C36000 is acceptable for all plumbing applications — it is not in hot chlorinated water. We advise on grade selection at DFM review. The correct grade costs marginally more; a field failure in a potable water system costs significantly more.
100
Machinability 100 — C36000 Always
We never substitute a slower-machining brass grade to reduce material cost when the application specifies or permits C36000. Lower machinability means slower cutting, more tool wear, worse surface finish, and less consistent dimensional results. C36000's machinability rating of 100 delivers the lowest cost-per-part for brass CNC work — not a different grade that is cheaper as a billet but costs more to machine.
Au
Gold Plating XRF Verified on RF Orders
Gold plating thickness measured by XRF for RF connector and signal contact pin orders. A 0.2μm nominal gold specification on a connector pin can vary from 0.05μm to 0.5μm across a plating batch without XRF measurement — the 0.05μm parts will fail contact resistance specification in service. We verify thickness per batch and document the measurement in the plating certificate.
G/N
Thread 100% Go/No-Go — Every Part
All threaded brass parts inspected with calibrated go/no-go gauges — 100% per piece, not sampled per batch. A batch with one out-of-tolerance thread that a sampling plan missed is an assembly problem at the customer. Thread gauge inspection is one of the lowest-cost quality operations in machining — there is no reason to sample it instead of 100% inspecting.
Foire aux questions

Brass CNC Parts — Questions fréquentes

Technical questions about brass grades, dezincification, plating, thread standards, and connector pin specifications.

C36000 (CuZn36Pb3, free-machining brass) is standard for fittings, connectors, terminals, nuts, and all threaded parts — machinability rating 100, best surface finish, self-lubricating thread quality. DZR (CW602N) for potable water fittings where dezincification is a risk. C377 Naval Brass for marine and brackish water applications. C172 BeCu for spring contact elements. C932 Bronze for high-load bushings requiring better wear life than brass. We advise on grade selection at DFM review — potable water applications always receive DZR without special request.
Nickel (3–10μm): most common — corrosion resistance, hard surface, base for gold/chrome. Tin (3–10μm): solderability on terminals and connector pins, RoHS. Gold flash (0.1–0.5μm/Ni): minimum contact resistance for signal connector pins — XRF verified on RF connector orders. Silver (5–15μm): RF connector contact surfaces, skin-effect optimised. Hard chrome (10–30μm): valve spool wear resistance. Zinc + chromate: general corrosion protection for hex and structural parts. All plating with plating certificate.
Dezincification is selective leaching of zinc from brass in hot chlorinated water — leaving a porous copper structure with no mechanical strength. Standard C36000 is susceptible. DZR (CW602N, ~0.05% As) resists dezincification — required for: potable water fittings in UK (WRAS), EU, and Australia; hot water systems above 50°C; garden irrigation fittings; and marine fittings in salt water. C36000 is acceptable for gas, air, oil, instrument air, and all non-potable-water applications. We specify DZR automatically for all potable water applications at DFM review.
Metric: 6H/6g standard; 4H/4h for precision instrument threads — optical comparator profile inspection. NPT (ANSI B1.20.1) for North American markets. BSPP/G (parallel) and BSPT/R (tapered) to BS 21/ISO 7 for UK, EU, and Australian markets. All threads inspected 100% with calibrated go/no-go gauges. Thread run-out to OD axis: ≤0.05mm standard; ≤0.01mm for precision instrument bodies. Miniature threads M1.0–M2.0 on Swiss-type CNC.
Yes — C36000 is the standard connector and contact pin material. Contact pin: OD h6, cylindricity ≤0,003mm, Ra ≤0.2μm. Gold (0.1–0.5μm/Ni) standard for signal contact pins. Swiss-type CNC for Ø0.5–Ø8mm at L/D > 10:1. RF connector body: OD h7; inner/outer bore concentricity ≤0,005 mm; silver plated to IEC 61169. Connector shell: OD h7, thread 6g, nickel or chrome plated. Bulk to 50,000 pieces in ESD packaging.
Brass C36000: machinability 100 (vs ~50 SS303), lower cost, self-lubricating thread, adequate corrosion resistance in gas, air, oil, and non-chloride water. Use brass for: gas, air, nitrogen, hydraulic mineral oil, instrument air, potable water (DZR grade), and electrical connectors. Use SS316L instead: chlorinated water exposure, marine salt water immersion, chemical processing, food contact, pharmaceutical contact, and temperatures above 200°C. Brass costs ~40–60% less than SS316L for equivalent precision parts — specify brass wherever environment permits.
Standard CNC turning: minimum practical OD ~Ø2mm. Swiss-type CNC (走芯机): minimum OD Ø0.5mm, L/D > 20:1 — C36000 is the ideal material for Swiss-type turning (machinability 100 > 12L14 at 83 for Swiss-type speeds). Contact pin OD h6, cylindricity ≤0.003mm, Ra ≤0.2μm, gold or tin plated. Tip geometry machined in same operation — pointed, flat, crown, or spherical radius.
