Brass CNC Machining
Well rounded properties make brass a versatile metal for CNC machined components.
What is Brass?
Brass is an alloying consisting of both copper and zinc. The gold material is a weather- and corrosion- resistant metal with tensile strength similar to mild steel. It's also an easy to machine material, so feedrates can remain high and coolant need is minimal.
Types of Brass for CNC Machining
- Brass C260
Brass C260, or cartridge brass, contains 70 percent copper and 30 percent zinc. The brass alloy has high ductility and is considered the most general purpose of all brass alloys. - Brass C360
Brass C360 remains the industry standard for general machining and high volume production. The excellent machinability characteristic of C360 permits full utilization of a screw machine’s capabilities.
Brass Machining Applications
- Automotive terminals
- Handles and hinges
- Jewelry
- Screws and rivets
- Valve stems
- Musical instruments
- Plumbing components
