Whether you need custom one-off prototypes or high-volume production runs, our engineering team is ready to work with your exact specifications.
What Are Lead Free Brass Machined Parts?
Lead free brass machined parts are precision-engineered components manufactured from brass alloys containing less than 0.25% lead by weight, complying with NSF 61, NSF 372, RoHS Directive, REACH regulations, and WRAS (UK Water Regulations Advisory Scheme) standards. Traditional free-cutting brass (CZ121 / CW614N) contains 1.8–3.7% lead; lead-free alternatives eliminate this health risk while retaining excellent machinability and corrosion resistance.

Top Questions About Lead Free Brass Machined Parts (SEO Q&A)
1. What is lead free brass used for in machined parts?
Lead free brass machined parts are used in drinking water valves, plumbing fittings, medical equipment, food processing components, and any application where lead migration must be eliminated. CW724R and C69300 are the most popular lead free turned component alloys.
2. What is the difference between CW724R and C36000 brass?
C36000 (CZ121/CW614N) is standard free-cutting brass containing up to 3.7% lead for machinability. CW724R (Eco Brass / C69300) replaces lead with bismuth/silicon, achieving comparable machinability with <0.09% lead — meeting NSF 372 and RoHS requirements.
3. Are your lead free brass parts NSF 61/372 certified?
We supply lead free brass machined parts manufactured from NSF 61/372-compliant alloys (CW724R, C69300) with full material traceability. We provide MTCs and RoHS/REACH declarations. Product certification under NSF 61 is typically obtained by the OEM — we supply compliant base material and precision-machined parts.
4. What tolerances can you achieve on lead free turned components?
Standard tolerance is ±0.02 mm; precision grade is ±0.01 mm; ultra-precision is ±0.005 mm depending on geometry and diameter. We use Mitutoyo CMM equipment for inspection of critical dimensions.
5. What is the minimum order quantity (MOQ) for lead free brass machined parts?
Our MOQ is flexible — we accept prototype quantities (even 1 piece for tooling validation) and scale to production volumes of 100,000+ pieces per month. There is no rigid MOQ; we quote based on your requirements.
6. Can you supply lead free brass turned parts to US/UK/EU standards?
Yes. We regularly supply lead free brass machined parts per ASTM B16, ASTM B124, BS EN 12164, BS EN 12165, DIN 17660, and JIS H 3250. Full material test certificates and compliance documentation provided with every shipment.
7. What surface finishes are available for lead free brass components?
Available surface finishes include: as-machined (natural brass), electroless nickel plating, electrolytic nickel plating, tin plating (matte or bright), chrome plating, silver plating, passivation, and custom coatings per customer specification.
8. How long does it take to produce lead free brass machined parts?
Standard lead time is 4–6 weeks from drawing approval and advance payment. Prototypes/samples can often be delivered in 2–3 weeks. High-volume repeat orders for stocked alloy grades can be expedited.
9. What is Eco Brass?
Eco Brass is a registered trade name for CW724R / C69300, a bismuth-silicon lead-free brass alloy developed by Wieland and Nibco. It is the industry’s leading lead free machined parts alloy for plumbing applications, with machinability approximately 70–80% of C36000.
10. Do you provide material test certificates (MTC) for lead free brass?
Yes. Every batch of lead free brass material we use comes with a full MTC from the brass mill, showing chemical composition, mechanical properties, and lead content verification. We pass these documents to customers as part of our standard delivery package.
11. Can you manufacture lead free brass parts to my CAD drawing?
Absolutely. We accept STEP, IGES, DXF, DWG, and PDF drawings. Our engineering team reviews your design and provides DFM feedback before production begins.
12. What industries use lead free brass turned components most?
The primary industries are: potable water and plumbing (WRAS/NSF markets), medical devices, food & beverage processing, HVAC, automotive (particularly EV battery systems), defence, and electronics.
13. Is your lead free brass RoHS and REACH compliant?
Yes. All our lead free brass alloys are RoHS 2011/65/EU compliant (lead <0.1% by weight in homogeneous material) and REACH SVHC-free. We supply SDS (Safety Data Sheets) and compliance declarations on request.
14. What plating is best for lead free brass machined parts in potable water?
For potable water applications, nickel plating (electrolytic or electroless) is the most common choice, providing corrosion resistance without adding lead. Some customers prefer tin plating for FDA food-grade applications. We advise based on your end-use environment.
15. How do you handle quality control for lead free turned components?
Our QC process includes: incoming material verification (XRF lead analysis), first article inspection (FAI), in-process SPC checks, and 100% dimensional inspection for critical features. Final shipment is accompanied by an Inspection Certificate and Certificate of Conformance (CoC).
16. Can you supply small batch lead free brass prototypes?
Yes. We regularly supply 5–50 piece prototype batches of lead free brass machined parts for customer trials, certification testing, and design validation. Prototype pricing applies, and production pricing is firmed upon drawing approval for bulk orders.
17. What is WRAS approval and do your lead free brass parts qualify?
WRAS (Water Regulations Advisory Scheme) is the UK standard for materials and fittings used in potable water supply. Our DZR brass (CW602N/CZ132) and bismuth brass (CW724R) alloys are WRAS-acceptable base materials. WRAS product approval is carried out by the OEM/fittings manufacturer; we supply the compliant machined components.
