A C3604 brass nozzle is used where conductivity, corrosion resistance and a clean machined finish matter without heat treatment. Below is the practical detail on C3604 brass nozzle supplied for electronics: high speed turning and milling of free-cutting brass and copper, the tolerance that is held, the finish applied and the documents issued with the parts.
Tolerance is applied where it does work rather than across the whole drawing. Critical features are held to ±0.02 mm, non-critical dimensions follow the general machining tolerance, and the difference is stated in the quotation rather than discovered later.

Manufacturing process
Work is carried out with high speed turning and milling of free-cutting brass and copper. Tooling, speeds and fixturing are recorded with the part number, so a repeat order starts from a proven process instead of a fresh setup.
Material is purchased against a certificate and checked on receipt, so the composition is known before any cutting starts. Work in progress is identified by part number and operation, and the finished parts are deburred, cleaned and protected before they leave the machine area.
Typical applications
Most of the work supplied in this category falls into the following examples.
- Plumbing and pneumatic fittings.
- Electrical terminals and contacts.
- Valve and pump components.
- Instrument and gauge bodies.
- Heat exchanger connectors.
Quality control and documentation
Critical features are measured on calibrated equipment in a controlled room, and the results are filed with the job so that a repeat order can be compared with the first.
Material certificates to EN 10204 3.1, dimensional reports and first article inspection reports are issued with the shipment where the application requires them. Calibration dates and measurement uncertainty are recorded alongside every result.
Ordering, lead time and packaging
Packaging is specified by the part: individual protection for finished surfaces, separation for assemblies, and export crating with a packing list for shipment.
Frequently asked questions
Why is brass preferred for fittings?
It machines freely, holds pressure tight faces and threads, resists dezincification in the right grade and needs no protective coating in normal service.
Can copper be machined to close tolerances?
Yes, but it demands sharp tooling, generous coolant and controlled speeds because it is soft and tends to smear rather than cut cleanly.
Can you supply material and inspection certificates?
Yes. Material certificates to EN 10204 3.1, full dimensional reports, first article inspection reports and, where required, PPAP or AS9102 documentation are issued with the shipment.
Drawings are reviewed for manufacturability before quotation, and any feature that adds cost without adding function is pointed out at that stage rather than after the parts are made.
