Brass Turned Parts

Jamnagar Brass Components is an experienced manufacturer of OEM brass turned parts for the automotive industry, supplying Tier 1 and Tier 2 suppliers and aftermarket component manufacturers across the USA, Germany, and Japan. Our CNC turning and multi-spindle automatic screw machine capabilities allow us to produce high-volume, precision-tolerance automotive brass components at competitive India-based pricing.

Automotive Brass Components We Manufacture

We produce a wide range of automotive brass turned parts including fuel system connectors and fittings, carburetor main jets, emulsion tubes, and needle jets, sensor housings and thermostat bodies, valve stems and valve seat inserts, fluid nipples and banjo connectors, oil and fuel filter components, power steering and brake system fittings, air conditioning refrigerant fittings, and transmission fluid connectors.

Brass Alloys for Automotive Applications

The primary alloy we use is CZ121 / C36000 free-machining brass for non-potable fluid systems. For fuel and coolant contact applications requiring lead-free compliance, we offer ECO Brass (CW510L) and CW602N DZR brass, both of which meet RoHS and California Prop 65 requirements. We can provide full REACH and RoHS compliance documentation.

Quality and Automotive Compliance

Our quality management system is certified to ISO 9001:2015, and we support customers requiring IATF 16949 aligned documentation. We provide PPAP documentation, FMEA, control plans, and MSA studies to support OEM supplier qualification. Dimensional inspection is performed using calibrated CMM equipment with full inspection reports provided per batch.

Production Volumes and Lead Times

We support prototype quantities through to high-volume production runs of hundreds of thousands of pieces. Standard lead times from order to shipment are 4 to 6 weeks for tooled components, with expedited production available for urgent requirements.

Frequently Asked Questions — Brass Turned Parts for Automotive

Q1: What automotive applications use brass turned parts?

Brass turned parts are widely used in automotive applications including fuel system fittings, carburetor jets and emulsion tubes, brake hydraulic fittings, coolant system connectors, electrical contacts and terminals, air conditioning fittings, dashboard and instrument panel inserts, gear shift bushings, and sensor housings. Brass is preferred for its corrosion resistance, machinability, and dimensional stability.

Q2: What brass alloys are used for automotive turned parts?

CZ121/C36000 free-machining brass (3% lead) is the most common alloy for automotive turned parts due to its excellent machinability and dimensional consistency. For fuel system and potable water applications, low-lead alloys (C69300, NSF 372 compliant) are specified. DZR brass (CW602N) is used for coolant fittings. Naval brass C46400 is used for higher corrosion resistance requirements.

Q3: What tolerances are achievable for brass automotive turned parts?

CNC turned brass automotive parts routinely hold ±0.025 mm (±0.001 inch) on critical diameters and thread pitches. Precision Swiss-type CNC turning achieves ±0.005 mm on small parts (below 20 mm diameter). Thread tolerances per ISO 965 (metric) or ASME B1.1 (UNC/UNF) are maintained with 100% gauge verification on all threaded features.

Q4: Can you supply brass parts to IATF 16949 automotive quality requirements?

We supply brass automotive components with full PPAP (Production Part Approval Process) documentation including dimensional reports, material certification, process flow, control plans, and MSA studies as required by OEM customers. Our ISO 9001:2015 quality system supports IATF 16949 requirements. PPAP Level 3 submission documentation is standard for new automotive programs.

Q5: What surface finishes are available for brass automotive turned parts?

Available surface finishes include as-machined (Ra 0.8–3.2 µm), bright polished (Ra 0.1–0.4 µm), electroless nickel plating (3–15 µm), bright tin plating (5–10 µm), chrome plating (decorative), zinc/chromate plating for corrosion protection, and clear lacquer for tarnish prevention. All plating is done on post-machining dimensions to maintain drawing tolerances.

Q6: What volume capability do you have for brass automotive turned parts?

Jamnagar Brass Components operates multiple CNC multi-spindle automatic lathes and Swiss CNC turning centres, supporting production volumes from 1,000 to over 1,000,000 pieces per year per part number. We support both new model introduction (NPI) prototype quantities and full-scale series production, with SPC monitoring for high-volume automotive parts.

Q7: How do you ensure traceability for automotive brass turned parts?

Full material traceability is maintained from raw material heat/lot number through to finished part shipment. Each production batch is linked to material test certificates, CNC machine program version, in-process inspection records, and final inspection report. Lot identification on packaging allows full traceability recall within our ISO 9001:2015 system.

Q8: What packaging options are available for automotive brass turned parts?

Packaging options include bulk loose in polythene-lined boxes (standard for non-critical surfaces), individual polythene bags (for plated or polished parts), compartmentalised trays or blister packs (for assembly line kitting), and custom returnable packaging to OEM specifications. Anti-tarnish VCI (Vapour Corrosion Inhibitor) paper or bags are included for export shipments.

Q9: Can you supply brass automotive turned parts to drawing?

Yes. We work directly from customer drawings in PDF, DXF, DWG, STEP, or IGES format. Our engineering team reviews drawings for manufacturability and provides DFM (Design for Manufacturability) feedback before quoting. First Article Inspection (FAI) with dimensional report and material certification is standard for all new part numbers.

Q10: What is the typical lead time and minimum order for brass automotive turned parts?

First article lead time: 2–4 weeks from approved drawings. Production lead time for series orders: 3–5 weeks including material procurement, machining, inspection, and export packing. Minimum order: 500 pieces for standard configurations; 1,000 pieces for plated parts. Air freight to USA/Europe takes 3–5 business days; sea freight takes 18–25 days.
