When should I choose brass? | Choose brass when your part requires excellent machinability, stable threads, corrosion resistance, electrical conductivity, decorative appearance or repeatable turned-part production. |
| Which brass grade should I choose? | C360 brass is commonly used for precision machined parts because of excellent machinability. C260, C464 or lead-free brass may be reviewed based on forming, corrosion, regulatory or application requirements. |
Is brass good for CNC turning? | Yes. Brass is widely used for CNC turned parts such as inserts, fittings, sleeves, bushings, pins, connectors and threaded components. |
Can you machine brass threaded inserts? | Yes. Brass threaded inserts, press-fit inserts, knurled inserts, heat-set inserts and custom threaded brass components can be reviewed based on drawing requirements. |
| Can brass parts be plated? | Yes. Nickel plating, tin plating, gold plating, chrome plating, clear coating, polishing and brushing can be reviewed based on appearance, conductivity, corrosion resistance and assembly needs. |
| Can you support RoHS or lead-free brass requirements? | Yes. If your project has RoHS, lead-free, potable water or regulatory requirements, material grade and certification expectations should be defined before quoting. |
Brass Capability
Brass CNC Machining Capability
Brass machining capability depends on material grade, part geometry, thread depth, OD/ID requirements, burr control, plating requirements, cosmetic surfaces and inspection method. Baosheng reviews CAD models and 2D drawings before machining to identify thread quality, knurling, plating allowance, burr-sensitive features and dimensional inspection requirements.

Material Fit
When to Choose Brass CNC Machining
Brass CNC machining is often selected when a part needs excellent machinability, stable threads, corrosion resistance, electrical conductivity, decorative appearance or repeatable production quality. It is commonly used for threaded inserts, fittings, bushings, sleeves, connectors, electrical hardware, valve components, decorative parts, sensor components and precision turned parts.
For maximum electrical or thermal conductivity, consider copper CNC machining. Lightweight structural parts may be better suited for aluminum CNC machining. High-strength or corrosion-critical parts may require stainless steel CNC machining or titanium CNC machining.
Choose brass when
You need stable threads, inserts, fittings, connectors, corrosion resistance, appearance or repeatable turned parts.
Review copper when
Maximum conductivity is more important than machinability, thread stability or decorative appearance.
Review lead-free brass when
RoHS, potable water or regulatory requirements are part of the drawing or customer specification.
Define plating early
Nickel, tin, gold, chrome or anti-tarnish requirements can affect thread fit, press-fit diameter and contact surfaces.
Grade Selection
Brass Grade Selection for CNC Machined Parts
The best brass grade depends on machinability, corrosion environment, lead content requirements, electrical performance, cosmetic surface, plating, cost and application. C360 brass is commonly selected for precision machined parts because it machines efficiently and supports clean threads. Lead-free brass should be reviewed when RoHS, potable water or regulatory requirements apply.
| Brass Grade | Typical Use | Notes |
|---|---|---|
| C360 Brass | Inserts, fittings, bushings, connectors, precision turned parts and general machined brass parts. | Common free-machining brass with excellent machinability and good thread quality. |
| C260 Brass | Electrical components, formed parts, decorative components and selected machined parts. | Often used where formability and appearance matter; machining suitability should be reviewed. |
| C464 Naval Brass | Marine-style hardware, corrosion-resistant brass components and selected fittings. | Used when better corrosion resistance is needed in selected environments. |
| C385 Brass | Architectural hardware, decorative components and selected visible brass parts. | Often considered for decorative or architectural applications. |
| Lead-Free Brass | Potable water, regulatory-sensitive or RoHS-related components when required. | Use when drawing, application or regulation requires lead-free brass. Availability and machining behavior should be reviewed. |
| Bronze Alternative | Bushings, bearings, wear components and higher-load sliding applications. | Consider bronze when wear resistance or bearing performance is more important than machinability. |
Process Selection
Brass CNC Machining Processes
Brass is one of the most machinable engineering metals, but production quality still depends on process planning. Thread quality, knurling, burr control, plating allowance, OD/ID consistency, surface finish and cosmetic handling should be reviewed before production.

Finishing
Surface Finishing for Brass CNC Parts
Brass surface finishing should be reviewed before machining because polishing, brushing, nickel plating, tin plating, gold plating, chrome plating and clear coating can affect appearance, plating thickness, thread fit, conductivity, solderability and inspection requirements. For connector parts, inserts or decorative brass components, cosmetic surfaces and plating requirements should be defined early.
If plating is required, thread tolerance, press-fit dimensions, electrical contact surfaces and masking requirements should be reviewed before production.
