Brass Turning Parts

Nuote Metals manufactures Brass Turning Parts to your drawings, from prototype to production, at our ISO 9001:2015 certified factory in China.

Brass is ideal for precision turning. It machines faster than steel, produces a smoother finish, and offers natural corrosion resistance and conductivity. But the real difference between suppliers is tolerance control and the ability to hold it across millions of parts.

Why Brass for CNC Turning?

Brass (copper-zinc alloy) offers properties that make it ideal for turned components:

• Excellent machinability: Low cutting resistance, high speeds, superior surface finish.

• Corrosion resistance: Resists rust and tarnishes slowly. No plating needed for many indoor uses.

• Conductivity: Effective electrical and thermal conduction—ideal for connectors and pins.

• Non-magnetic: Essential for electronics and sensitive instruments.

• Strength and ductility: Holds threads well and resists deformation.

Common brass alloys we machine:

• C36000 (Free-cutting brass): Most machinable. Best for high-volume parts.

• C26000 (Cartridge brass): Higher strength, excellent ductility. Best for structural connectors.

• C11000 (ETP copper): For maximum conductivity when brass is not sufficient.

Our CNC Turning Capabilities

Nuote Metals operates multi-axis CNC lathes with live tooling and bar feeders. We produce complex geometries—cross-holes, threads, grooves, knurls—in a single setup, reducing lead time and improving consistency.

Prototype to production: We machine single prototypes for validation, then scale to production with the same tooling and process controls—ensuring the approved part is the part you receive.

Applications – Where Brass Turning Parts Are Used

Electronics & communications: Connector pins, RF shielding components, grounding contacts.

Automotive: Sensor housings, fuel system fittings, electrical terminals.

Plumbing & fluid control: Valve cores, stems, threaded adapters, faucet cartridges.

Instrumentation: Gauge components, optical mounts, precision adjusters.

Industrial equipment: Pneumatic fittings, hydraulic connectors, machine tool parts.

A specific example: A European sensor manufacturer required a C36000 brass housing with a 0.008mm bore tolerance and Ra 0.4μm internal finish. Our turning department produced the part in a single setup on a multi-axis lathe, holding the bore tolerance across a 50,000-piece run. The customer eliminated a secondary honing operation and reduced unit cost by 18%.

Quality Control – How We Hold ±0.005mm

Tolerance claims mean nothing without process control. Every Brass Turning Part ships under a documented quality system:

Incoming material verification:

Mill test certificates for every brass coil—alloy, temper, and impurity levels verified.

In-house hardness and conductivity checks.

In-process monitoring:

First Article Inspection (FAI) for every new part number.

Statistical Process Control (SPC) on critical dimensions.

Tool wear monitoring and scheduled tool changes to prevent drift.

Final inspection:

CMM inspection for complex geometries.

Optical comparators for profile and thread verification.

Surface roughness testers for Ra validation.

Full dimensional report with every shipment.

Certifications: ISO 9001:2015. RoHS and REACH compliance available. Material certificates and inspection reports accompany every order.

How to Request a Quote for Brass Turning Parts

Send us your drawing (STEP, IGES, PDF, or DWG) with:

• Material and temper (or allow us to recommend)
• Tolerance requirements for critical dimensions
