Product overview
CW614N precision turned components
CW614N is the European material number for CuZn39Pb3, a leaded brass used extensively for free-machining applications. Turned components include bushings, threaded inserts, spacers, adapters, collars and small fasteners made to an engineering drawing. Brass Parts India accepts custom-part enquiries from electrical OEMs, EPC contractors, utilities and distributors. A usable specification combines the material number with a product standard, supply condition and dimensional requirements. The component drawing then controls the geometry and functional interfaces of the delivered part.
CuZn39Pb3 chemistry and purchasing identity
The chemical symbol CuZn39Pb3 describes the nominal alloy family rather than an exact batch analysis. Zinc is the balance after copper, lead and permitted minor elements are accounted for. EN 12164 is a relevant specification for free-machining rod, while other product forms use their applicable standards. A mill certificate should be checked against the ordered grade and edition. Chemical conformity alone does not establish the temper, tensile properties or dimensional tolerances needed for a specific stock size and finished component.
Precision shoulders and concentric turned surfaces
CW614N is useful for parts in which a bore, outside seat and shoulder must work together. The drawing should state the datum scheme and any runout, perpendicularity or positional requirement that controls assembly function. Excessively tight tolerances on nonfunctional surfaces can increase manufacturing effort without improving the product. A review should concentrate control on mating features, sealing interfaces and areas that determine alignment. Distinguishing these requirements helps both the producer and receiving inspector use the same practical definition of an acceptable component.
Insert geometry and repeat assembly
Threaded inserts and standoffs made from CW614N may incorporate external knurls, grooves or shoulders for retention. The correct configuration depends on the host material, installation method and available wall thickness. A larger knurl does not necessarily improve retention if it damages the surrounding material or reduces the insert wall. Thread quality, burr control and lead-in geometry influence assembly consistency. Qualification of torque-out, pull-out and repeated tightening should use production-representative parts in the actual mating material and installation process.
European drawings and legacy CZ121 references
CW614N is commonly cross-referenced to CZ121Pb3 and the older CuZn39Pb3 material naming system. This relationship helps interpret legacy drawings, but the original specification still matters. Some drawings state CZ121 without a lead variant, and that omission should be resolved before purchasing material. C38500 also appears in commercial comparison tables for this family, whereas C36000 belongs to a different comparison group. A material change should be documented and accepted, especially where an OEM maintains an approved material list.
Industrial supply and finish coordination
CW614N parts can be requested with natural brass surfaces or suitable plated finishes for the intended equipment. Surface preparation, coating thickness and coverage must be coordinated with thread and bore tolerances. A plated sleeve may fit differently from an uncoated approval sample even when both were machined to the same dimensions. State final dimensions after finishing and identify surfaces that need masking. Packing should protect small machined edges and keep distinct part numbers separated so that correct parts remain identifiable during incoming inspection and assembly.
Key features
- Custom component geometry based on controlled drawings and specifications.
- Material selection identified by grade, product standard and required condition.
- Turning, drilling, threading and secondary features reviewed for the part.
- Natural brass, electro-tinned or nickel finish options by agreement.
- Metric and imperial thread requirements supported by complete callouts.
- Inspection scope and repeat-order identification agreed before manufacture.
Drawing-controlled dimensions
Turned diameters, bores, shoulders and seating faces can be specified around the functional requirements of the assembly. Identify the datum from which each critical feature is measured, then define the fit or geometric control needed at the mating interface. Tolerances should be realistic for the part length, wall thickness and finishing route. Agree which dimensions are checked on every batch and which require additional sampling. This creates an inspection plan that supports assembly performance without treating every decorative or clearance surface as equally critical.
Internal and external thread options
Threaded brass components can be specified with metric or imperial threads to suit existing equipment. The parent product range lists ISO metric, BSW, BA, BSF, UNC, UNF and UNEF options. Each order should name the thread standard, pitch, tolerance class, engagement and any required relief. For plated parts, state whether gauging applies after coating. Blind holes also need a usable thread depth and drill-depth limit. A complete thread callout prevents confusion between nominal thread length and the portion that can carry the mating fastener.
Machined surface finish and edge control
Surface roughness should be stated where it affects sealing, sliding, contact or appearance. A smooth-looking surface is not a measurement, and a general finish note may not identify the critical location. Chamfers and radii help assembly but must not remove necessary thread engagement or sealing area. Cross holes, slots and internal intersections deserve specific burr checks. Define acceptable edge treatment on the drawing so that deburring removes loose material while preserving the designed geometry, especially around small contact pins and thin machined sleeves.
Natural brass, tin and nickel finishes
The finish families on the parent range include natural brass, electro-tinned and nickel surfaces. Select a coating for its intended function and compatibility with the mating material. Specify coating thickness, areas to be masked, appearance criteria and any adhesion or corrosion test required by the equipment specification. Coatings alter dimensions and may affect thread fit, solderability or electrical contact behaviour. Approve the finished condition using representative samples, rather than assuming that an uncoated dimensional report proves conformity of the plated production part.
Part identification and repeat-order control
Stable repeat supply starts with a consistent part number and drawing revision. Include the ordered material, approved finish, batch quantity and packaging requirements on the purchase order. If marking the component is impractical, agree an appropriate label and batch identification method. Keep similar variants separated, particularly when they differ only in bore size, thread pitch or plating. For distributors, a clear stock description should distinguish the alloy from the component type. This reduces the chance that visually similar hardware is issued against the wrong customer specification.

Application names indicate where enquiries arise; they do not establish a rating for every part in the range. Define installation loads, operating temperature, corrosion exposure and maintenance needs. Where a component enters regulated equipment, specify the relevant approval and testing requirements before design release. For replacement supply, verify the original drawing and equipment requirements rather than selecting solely by the appearance of a sample.
Manufacturing process
1. Drawing review and stock selection
Manufacture begins by reviewing the drawing revision, material standard, dimensions, finish and order quantity. The review identifies critical datums, thread requirements and inspection records. Stock form and condition are selected for the approved production route. For a forged component, the blank design additionally needs draft, radii, parting-line placement and machining allowance. Any material substitution should be resolved before stock is released to production.
2. Forming and precision machining
Turning produces the principal diameters, shoulders and faces from suitable stock. Drilling, boring and threading create internal features, and secondary operations add flats, cross holes or slots. The sequence is chosen to maintain the relationship between functional surfaces. Slender sections, deep holes and interrupted cuts need appropriate support and tooling. Process settings are established for the actual part rather than copied from a generic alloy description.
3. Finishing, inspection and packing
Deburring and cleaning remove loose edges and machining residue before final inspection or the agreed surface treatment. When plating is required, final dimensions and thread fit should be verified in the finished condition. The inspection scope follows the order requirements. Packaging then protects surfaces and maintains part identification through dispatch, receiving inspection and storage. Special cleanliness or individually separated packing should be stated at enquiry stage.

Frequently asked questions
Is CW614N the same as CuZn39Pb3?
CW614N is the European material number associated with CuZn39Pb3. CZ121Pb3 is a common legacy cross-reference. The ordered product standard and temper still govern acceptance, so a commercial grade comparison cannot replace a review of the purchase specification.
What information is needed for a quotation?
Send a dimensioned drawing, material standard, quantity, finish and delivery destination. Include the drawing revision, critical tolerances, required inspection documents and intended application. If only a sample is available, identify which characteristics must be reverse-engineered and which material requirements are already known.
Is the listed rate per part or per kilogram?
The displayed rate is US$ 13.90/kg. A kilogram rate is different from a unit price. Provide the finished-part weight and order quantity so the quotation can state the applicable weight basis, tooling, finishing, packing, freight and taxes clearly before purchase.
Can I order a custom thread or non-standard geometry?
Submit the complete thread callout and component drawing for review. Custom shoulders, slots, cross holes, knurls and bores need dimensional and inspection requirements. Manufacturing feasibility depends on the geometry, stock form and quantity; acceptance is confirmed in the quotation.
Are international equivalents automatically interchangeable?
No. A cross-reference is a starting point for material review. Compare the ordered standards, composition limits, temper, product form and mechanical properties. A substitute should be accepted in writing before production, especially when the part belongs to a controlled OEM design.
Can these parts be used in electrical equipment?
They can be considered for suitable electrical component designs. Current rating, temperature rise, conductor retention, contact resistance and insulation clearances are properties of the complete assembly. The equipment designer must establish those requirements and validate the finished configuration where necessary.
Are these alloys lead-free or automatically compliant?
These are leaded brass families. Do not describe them as lead-free. Regulatory conformity depends on the application, destination, applicable rules and any valid exemption. Request current material and compliance documentation for the specific order; a generic alloy designation is not a compliance certificate.
What tolerances and surface roughness are available?
Dimensions and roughness are agreed against the drawing after manufacturing review. There is no universal tolerance or finish applicable to every component in this range. Identify functional surfaces and final dimensions after plating so inspection measures the condition the assembly actually requires.
Can inspection reports or material certificates be supplied?
Specify the required records at enquiry stage, including material certification, dimensional reports and any special tests. The quotation should confirm the agreed scope and document format. A raw-material certificate and a finished-part inspection report cover different aspects of conformity.
How do I arrange repeat orders?
Quote the approved part number, drawing revision, material, finish and previous order reference. State the next batch quantity and delivery requirement. Any design, material or finish change should be reviewed before release so the next batch remains compatible with the approved assembly.
