Why Choose Brass for Your CNC Machined Components?
Brass, an alloy of copper and zinc, is a highly sought-after material in CNC machining for its well-rounded and advantageous properties. Its versatility makes it a reliable choice for components that demand both performance and a high-quality finish. The specific ratio of copper to zinc, along with the addition of other elements like lead, can be adjusted to create various alloys with distinct characteristics, allowing for precise material selection based on application requirements.
One of the most significant advantages of brass is its outstanding machinability. According to WayKen Rapid Manufacturing, alloys containing lead, such as C360 brass, are often called "free-machining brass" for this reason. This property allows for high-speed cutting and faster feed rates, which reduces machining time and lowers production costs. The material cuts cleanly without excessive tool wear, ensuring a smooth surface finish directly off the machine. This efficiency makes it an economical option for both small and large production volumes.
Beyond its workability, brass offers excellent resistance to corrosion. This durability makes it suitable for parts used in damp environments or those that handle fluids, such as plumbing fittings and marine hardware. The material is also a great conductor of both heat and electricity, a property inherited from its primary component, copper. This makes it an ideal material for electrical connectors, terminals, and various electronic components. Furthermore, brass has a low coefficient of friction, which is beneficial for applications involving moving parts like bearings and gears.
Common Brass Alloys for CNC Milling
While many brass alloys exist, two are particularly common in CNC machining due to their optimized properties:
- Brass C360 (Free-Machining Brass): As the industry standard for high-volume production, C360 contains a higher percentage of lead, which dramatically enhances its machinability. It offers good tensile strength and is perfect for parts requiring intricate detail, such as screws, valve components, and fittings.
- Brass C260 (Cartridge Brass): Comprised of approximately 70% copper and 30% zinc, C260 is known for its high ductility and formability. It is often used for applications that require cold working, such as ammunition cartridges, radiator cores, and decorative hardware.
