Quality Control

Brass Lots Inspected and
Documented

CMM inspection of a machined aluminium part
  • 01

    Incoming material

    Brass bar is checked against the mill certificate and heat number, so grade and lot are confirmed against your drawing before any cutting starts.

  • 02

    First article inspection

    One brass piece is checked feature by feature on the CMM, and you receive the FAI report. Production is released only on your sign-off.

  • 03

    In-process SPC

    During the run, operators sample parts to an AQL plan. Drift on a turned diameter or thread is caught at the machine, not at final inspection.

  • 04

    Final inspection

    Every lot, not a sample, gets a 100% dimensional and visual check. The material certificate and inspection record ship with it, with traceability from raw material to finished part. See how we inspect a precision-machined part.

FAQs

Brass Questions,
Answered.

Ask a Question
  • What file formats can I upload for a quote?

    A STEP or IGES model plus a 2D PDF or DWG drawing with GD&T is ideal. SolidWorks and ProE files are also accepted. Add quantity and turnaround for a quote within one business day. An NDA is available on request before quoting.

  • Is C36000 brass lead-free?

    No. C36000 is a leaded free-machining brass. If your part must be lead-free or meet a specific RoHS, REACH or potable-water requirement, state it on the drawing before quoting so the grade can be reviewed. The material certificate records grade and heat.

  • What tolerances can you hold in brass?

    Turned diameters hold ±0.01 mm and ground diameters ±0.005 mm. Roughness defaults to Ra 1.6 µm, with Ra 0.4 µm available when the drawing requires it. Critical features are confirmed at drawing review. See machining tolerances for how to specify them.

  • Can you handle prototypes and high volumes?

    Yes. Orders start at one piece, with fast prototypes in 3 days and production typically in 4–6 weeks. Runs scale to 100,000+ pieces across CNC machining, Swiss turning and general turned parts.

  • Which brass grades and finishes do you offer?

    C36000 free-machining brass and C37700 forging brass. Finishes include nickel, electroless nickel, chrome and tin plating on request, plus bead blast, polishing or as-machined.

  • Do you provide material certificates and inspection reports?

    A material certificate and inspection record ship with every lot. Parts are made under an ISO 9001:2015 quality system with traceability from raw material to finished part. FAI and PPAP packages are available on request.
