CW614N vs CW617N – Understanding the Difference
Both CW614N and CW617N are leaded free-machining brasses under the European EN 12164/12168 standard, but they have distinct compositions and application strengths:
| Property | CW614N (CuZn39Pb3) | CW617N (CuZn40Pb2) |
|---|---|---|
| Copper % | 57–59% | 57–59% |
| Lead % | 2.5–3.5% | 1.6–2.5% |
| Zinc % | Balance (~39%) | Balance (~40%) |
| Machinability Rating | 100% (benchmark) | 90–95% |
| Corrosion Resistance | Good | Good–Very Good |
| Tensile Strength | 380–450 N/mm² | 380–430 N/mm² |
| Best For | Maximum speed CNC/screw machine work | Fittings, valves, higher corrosion environments |
| UK/BS Equivalent | CZ121 | CZ122 |
| US Equivalent | C36000 | C37700 |

CW614N Brass Machined Parts – Products
CW614N CNC Turned Parts and Screw Machine Components
CW614N is the ultimate free-machining brass — 100% machinability rating means the highest cutting speeds, longest tool life, and best surface finish of any brass alloy. Brass Parts India produces high volumes of CW614N CNC turned components including bushings, spacers, standoffs, terminals, connectors, ferrules, valve stems, nozzles, and custom shapes. Tolerances to ±0.01 mm. Quantities from 1,000 to 10 million pieces.
CW614N Electrical Hardware and Terminal Components
Terminal screws, earth bolts, cable gland bodies, socket pins, plug contacts, relay components, and switchgear hardware. CW614N’s good electrical conductivity (~26% IACS) and ease of machining make it the preferred material for electrical connector and switchgear manufacturers worldwide.
CW614N Threaded Inserts and Moulding Inserts
Brass threaded inserts for plastic injection moulding and compression moulding — knurled, flanged, and heat-set types. Used in electronics enclosures, automotive trims, appliance bodies, and structural composite panels.
CW617N Brass Machined Parts – Products
CW617N Plumbing and Gas Fittings
CW617N (lower lead content, slightly higher zinc) is the preferred grade for plumbing compression fittings, push-fit connectors, gas fittings, valve bodies, and radiator connections where higher corrosion resistance and dezincification resistance (when treated) are required. Manufactured to BS EN 1254, ASTM B140, DIN 3384, and ANSI standards.
CW617N Valve Components and Ball Valve Bodies
Precision-machined CW617N valve stems, ball valve bodies, gate valve components, check valve parts, and needle valve seats. Available in 1/4″ BSP to 4″ BSP and NPT thread forms. Tested for pressure integrity per customer specifications.
CW617N HVAC and Refrigeration Fittings
Flare fittings, sweat fittings, SAE 45° and 37° JIC fittings for copper tube HVAC systems. CW617N resists the mild corrosion encountered in refrigerant and chilled water systems. Compatible with R-22, R-410A, and other refrigerants per ASHRAE standards.
CW617N Hydraulic and Pneumatic Components
Push-in fittings, push-to-connect couplings, manifold blocks, orifice plugs, and quick-release connectors in CW617N brass. Manufactured to Parker Hannifin, SMC, and Festo interface standards on request.

Frequently Asked Questions – CW614N and CW617N Brass
Q1: When should I specify CW614N vs CW617N?
A: Use CW614N when maximum machinability and production speed are the primary criteria — electrical components, high-volume screw machine parts, inserts. Choose CW617N when slightly better corrosion resistance or dezincification resistance is needed — plumbing fittings, valve bodies, gas components. For most general engineering applications either grade is suitable.
Q2: Are CW614N parts RoHS compliant?
A: CW614N contains up to 3.5% lead, which is technically above the RoHS 0.1% threshold for most product categories. However, it benefits from a RoHS exemption (Annex III, Exemption 6c) for “lead as an alloying element in brass up to 4% by weight.” This exemption covers many applications including electrical connectors and fittings. We provide RoHS compliance letters citing the applicable exemption. For fully lead-free requirements, we offer CW625N, CW626N, or silicon brass alternatives.
Q3: What is the minimum order quantity for CW614N/CW617N parts?
A: Prototype/sample: 50–100 pieces. Production runs: typically 1,000 pieces minimum per part number. High-volume standard components: no minimum. We accommodate blanket purchase orders with scheduled monthly releases.
Q4: Can you match existing supplier samples?
A: Yes. Send us a sample part or detailed drawing and we will produce first articles for your approval before full production. First article inspection reports (FAIR/PPAP Level 3) available.
