Modern vehicles contain many small brass parts: sensor housings, connectors, fuel and brake-line fittings, valve components, bushes and terminals. They are often invisible to the end user but critical to performance.
Why brass?
Brass machines accurately and economically, resists corrosion and conducts electricity well. Free-cutting grades such as CW614N allow high-volume turned production, while forged grades suit pressure-bearing fittings.
What automotive buyers typically ask for
- Tight, repeatable tolerances — held across the whole lot, not just the first-off sample.
- Traceability — lot numbers that link finished parts to material certificates and inspection records.
- Documentation — inspection reports and material certificates; some programmes also request control plans and capability data.
- Consistent plating or finish — especially for connectors and terminals.
- Packaging suited to assembly lines — counted quantities, labelling and protection of threads.
Design details that help
Knurls, shoulders and thread forms can be designed to resist loosening under vibration and thermal cycling. Marking critical-to-function dimensions on the drawing allows inspection effort to focus where it matters.
Start a conversation early
Automotive programmes often have specific supplier requirements. Share them at the enquiry stage — documentation level, annual volume, packaging and delivery pattern — so that we can confirm what we can support before you commit.
