Brass
Durable, distinctive golden color, strong, easily machinable for detailed components. Leaded free-cutting brass offers low machining resistance, excellent surface finish, and minimal tool wear, suitable for precision threads, gears, and thin-walled components. It is an economical and practical material for CNC machining.
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 feed rates 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.

Lead-bearing free-cutting brass offers excellent machinability and causes minimal tool wear, making it suitable for high-speed, precision, mass production.
A mainstream China domestically produced free-cutting brass featuring good machinability and hot-forging properties. It is widely used in valves, hardware, and structural components.
Standard brass offers a balance of strength and ductility with excellent formability, making it suitable for electrical structural components and stamped housings.
Tin-containing naval brass offers excellent resistance to seawater corrosion, making it the preferred choice for marine hardware and heavy-duty applications.
Lead-free, eco-friendly brass with machinability comparable to leaded materials; compliant with RoHS and drinking water regulations.
Commonly known as "Muntz metal" or 60/40 brass, it is an α+β duplex brass. It features high strength, resistance to seawater corrosion, and excellent hot-working properties, making it suitable for use in marine vessels, heat exchangers, and heavy machinery components.
Also known as 63/37 brass, it offers higher strength than pure copper, though it ranks among the lower-strength varieties of ordinary brass. It features excellent cold-formability and is not prone to stress corrosion cracking. It is widely used for components in electronics and electrical equipment, the automotive industry, and consumer hardware.
Brass CNC machined parts naturally offer a warm golden appearance, good surface quality, and excellent machinability. However, the right surface finish can further improve corrosion resistance, wear performance, appearance, solderability, and long-term product reliability. At Longwang, we help customers select suitable finishing options based on part function, tolerance requirements, operating environment, and visual expectations.
As Machined
Standard finish, surface roughness of 3.2 μm (126 μin), removes sharp edges and deburs parts cleanly.
Tumbling
Utilizes barrel or vibratory processes with abrasives to smooth and polish the surface of parts.
Heat Treatment
Alters the physical (and sometimes chemical) properties of a material to achieve desired mechanical properties.
Brass is one of the most popular metals for CNC machining because it combines excellent machinability with good mechanical properties, corrosion resistance, and an attractive appearance. It is especially suitable for precision turned parts, fittings, connectors, bushings, valves, and decorative components.
pros
cons
CNC machined brass parts are widely used across electronics, automotive, plumbing, smart home, industrial equipment, and precision hardware applications. Thanks to its machinability, corrosion resistance, conductivity, and premium appearance, brass is suitable for both functional and decorative components.
