Why Brass Alloys Make Sense for CNC Machining
Excellent machinability
Brass alloys such as C360 are among the easiest metals to CNC machine, allowing high cutting speeds and excellent surface finishes.
Good corrosion resistance
Brass resists corrosion in air and many water environments, making it suitable for valves, fittings, and decorative hardware.
Good electrical and thermal conductivity
Brass provides better conductivity than many steels, making it useful for electrical connectors, terminals, and heat-transfer parts.
Attractive appearance
The natural golden color of brass is suitable for visible components, nameplates, instruments, and decorative precision parts.
