Brass Materials & Surface Finishing
Common brass materials for CNC machining — plus customer‑specified grades upon request.
Brass 360
Commonly machined free‑cutting brass for efficient CNC production.
- Excellent machinability
- Good strength
Fittings, bushings, Musical instruments,connectors, precision turned components.
Brass 260
Versatile alloy with good formability and corrosion resistance.
- Good formability
- Decorative finish
Decorative components, electrical parts, general mechanical components.
Other Brass Alloys
Machmaster can review customer‑specified brass grades based on mechanical requirements, machinability, application, and surface finish.
Specify the required brass grade on the drawing or purchase specification.
Finishing options according to appearance and functional requirements.
As Machined
The part is left as-is from CNC machining, offering a cost-effective solution with visible tool marks and a standard roughness of 3.2 μm (126 μin), plus deburring for safe handling.
Bead Blasting
Bead blasting produces a uniform matte finish by removing surface imperfections. Commonly used to improve appearance before anodizing, plating, or coating.
This dry finishing process applies powder to metal parts, then cures it into a tough, uniform coating. It offers excellent durability and is available in many colors and textures.
Polishing removes surface flaws and creates a reflective, smooth finish. It’s used to improve aesthetics, reduce friction, and prepare parts for secondary coatings.
Brushing applies a fine, directional texture using abrasive belts or pads. Often used for decorative metal finishes or to visually mask minor surface defects.
Brass Alloy Properties Overview
| Material | CNC Process | Ultimate Tensile Strength | Elongation | Hardness (HRB) |
|---|---|---|---|---|
| Brass C260 | Milling | 62 ksi | 30% | 70 HRB |
| Brass C360 | Turning | 58 ksi | 25% | 78 HRB |

FAQ: Brass CNC Machining
What Types Of Brass Do You Machine?
We commonly work with brass grades like C360 and C260. If you need other types, such as naval brass or European equivalents, we can evaluate them based on your project requirements.
Is Brass Easy To Machine Compared To Other Metals?
Yes. Brass, especially C360, is one of the most machinable metals, ideal for high-speed CNC turning and milling with minimal tool wear.
Do You Offer Surface Finishing For Brass Parts?
Yes. We provide polishing, sandblasting, plating (such as nickel or chrome), and custom finishes to enhance appearance and protect against corrosion.
What Industries Commonly Use CNC Brass Parts?
Brass parts are widely used in electronics, plumbing, automotive, decorative hardware, musical instruments, and precision engineering.
Can You Support Prototypes And Low-Volume Orders?
Absolutely. We offer flexible production, from single-piece prototyping to large-scale runs, all with consistent quality and tight tolerances.
How Fast Can I Get My Brass Parts?
Lead times vary by part complexity and quantity. Standard prototyping can be delivered in 5–7 working days. We also offer expedited services.
