What Type of Brass Can Be Used as CNC Milling Material?

Brass is a commonly used material for CNC milling due to its excellent machinability, and the commonly used brass alloy for CNC milling is 360 Brass.

360 Brass (Free Machining Brass) is known for its excellent machinability, meaning it cuts easily and cleanly with minimal tool wear. It also has good strength, corrosion resistance, and is relatively inexpensive. It is often used in applications where ease of machining is critical. However, it contains lead, which improves the machinability but may not be suitable for certain applications where lead content is a concern.

What are the Applications of CNC Machining Small Brass Parts?

CNC machining small brass parts is a versatile process that finds application in various industries. The specific applications of CNC machining small brass parts include:

1. Electronics and Electrical Components: Small brass parts are commonly used in electronics for connectors, terminals, and other components due to their electrical conductivity.
