Brass is a combination of copper and zinc, commonly used as an alloy in CNC machining. This material is known for its exceptional machinability, corrosion resistance, and attractive appearance. This material is highly machinable, allowing for high feedrates and minimal coolant requirements. With the addition of lead, brass becomes incredibly easy to work with, making it the most machinable option among all copper alloys. These properties make CNC machining brass a great choice for mechanical applications that need corrosion resistance, like those found in the marine industry.

Brass CNC turned parts can undergo various surface finishing processes to enhance their appearance, durability, and performance.
Brass machining offers numerous advantages, making it a popular choice for various industries. However, it is essential to consider both the benefits and limitations to determine if it is the right material for your specific application.
Brass has been used for many years in a wide range of applications. These include plumbing fittings, electrical connectors, ammunition casings, musical instruments, decorative items, and various consumer and industrial products. Its versatility, appealing appearance, and ease of use have all contributed to its widespread adoption across various industries. Here are a few examples of commonly CNC-machined custom brass parts:
Yes, brass is an excellent material for machining due to its low friction coefficient and excellent machinability. It allows for precise cutting and shaping, making it ideal for detailed and intricate parts.
Brass is highly rated for machinability and is often considered one of the easiest materials to machine. Its ease of cutting and minimal tool wear contribute to efficient and cost-effective machining processes.
Recommended cutting speeds for brass vary depending on the specific alloy and machining process. Generally, cutting speeds for brass range between 100 to 300 meters per minute. The appropriate cutting speed helps maintain tool life and achieve a high-quality finish.
Brass generally offers easier machinability than aluminum. Compared to aluminum, brass has a lower tendency to stick to tools, allowing for faster machining at a lower power. Brass’s lower friction coefficient and superior chip formation result in less tool wear and higher precision during machining operations. Brass C360 is a highly machinable brass alloy, making it commonly referred to as free-machining brass.
