The Guide to 3D Printing with Steel
Brass machining combines precision, strength, and beauty. This alloy’s gold-like appearance and excellent machinability make it ideal for countless industries—from electronics to automotive manufacturing.
If you’re planning a CNC project with brass, here’s what you need to know about its benefits, challenges, and machining processes.
Why Engineers Choose Brass
Brass offers a rare mix of durability, workability, and style. It’s one of the easiest metals to machine, which is why engineers rely on it for fast, high-quality production.
Easy to machine: Brass cuts cleanly, allowing precise shapes and smooth finishes with minimal tool wear.
Corrosion-resistant: Performs well in humid or wet environments, such as plumbing or marine fittings.
Electrically conductive: Common in connectors, switches, and terminals.
Visually appealing: Its warm gold tone makes it ideal for visible or decorative parts.

Standard Brass Alloys in CNC Production
Each brass alloy serves a specific purpose depending on the application:
C360 Free-Cutting Brass: Highly machinable and perfect for gears, fasteners, and valves.
C464 Naval Brass: Offers excellent resistance to saltwater—ideal for pumps and marine hardware.
C385 Engraving Brass: Provides a bright finish for decorative plates, handles, and nameplates.

Challenges When Machining Brass
Brass is forgiving but still requires precision to maintain quality.
Chip management: Long chips can build up; optimal speeds and cutting tools prevent jams.
Heat control: Brass disperses heat well, but coolants help extend tool life.
Surface finish: Proper feeds and tooling avoid marks or deformations.
Our engineers and partners ensure your parts meet the exact tolerances and finishes you expect.
CNC Processes Used for Brass Parts
Different CNC operations can shape brass efficiently:
Milling: A rotating tool removes material to form detailed features like threads or slots.
Turning: The part rotates while a stationary tool shapes cylindrical components.
Cutting: High-speed blades prepare blanks for milling or turning.
Engraving and Finishing: Brass’s malleability allows detailed engravings and mirror-like polishing.
