Common Brass Alloys for CNC Machining

Here are the brass alloys we commonly use for CNC machining, along with essential properties to guide your material choice.

Alloy/Grade	Key Properties	Typical Tensile Strength (MPa)	Yield Strength (MPa)	Hardness (HB)	Machinability
C260 (Cartridge Brass)	Excellent ductility, corrosion resistance	345	170	90	Excellent
C360 (Free-Cutting Brass)	Superior machinability, good strength	360	210	95	Excellent
C464 (Naval Brass)	High corrosion resistance, strength	410	250	105	Good
C345 (Lead-Free Brass)	Environmental compliance, good machinability	345	200	90	Good
C280 (Muntz Metal)	High strength, wear resistance	400	240	100	Good

CNC Machining Processes for Brass

To produce high-precision brass components, Beska applies a combination of advanced machining methods tailored to each part’s geometry and function.

CNC Milling and Turning

Multi-axis CNC milling centers, Mazak turning machines, and Swiss-type lathes handle complex geometries, small diameters, thin walls, and intricate contours.

Secondary Operations

At Beska, we can also perform threading, knurling, slotting, tapping, and reaming in-house, reducing the need for external suppliers.

Quality Assurance

Each brass component undergoes strict dimensional checks using CMM and visual inspections to guarantee specifications are met.

Typical Brass Components We Produce

At Beska, we machine a wide range of custom brass parts for various industries, with attention to material selection, achievable tolerances, and machining complexity.

Valve bodies and pump housings — Typically machined from C360 or C464 brass for good corrosion resistance and machinability.
Electrical connectors, terminals, and contact pins — Often made from free-cutting brass like C360 for easy machining and plating compatibility.
Decorative and architectural fittings—Materials such as C260 or C360 are common.
Gears, bushings, and precision mechanical parts— Usually produced from C360 or lead-free brass for wear resistance.
Custom prototypes and low-volume runs — Can be produced in various brass alloys depending on functional requirements.

Each part is produced with consideration of machinability, material properties, and functional requirements, ensuring components are precise, durable, and fit for their intended application.

FAQ

Which brass alloy is best for CNC turning or milling?

For highest machinability and cost efficiency, C360 Free-Cutting Brass is ideal. For marine or outdoor use, C464 Naval Brass resists corrosion. For drinking water or lead-free compliance, C345 or C693 Eco Brass are recommended.

How does brass compare to aluminum for CNC machining?

Brass offers better machinability, superior electrical conductivity, and an attractive natural finish, while aluminum is lighter and often less expensive. We can advise on the best material based on your application’s strength, weight, and cost targets.

Can brass parts be plated or finished after CNC machining?

Yes. We provide in-house deburring and polishing and can coordinate nickel, chrome, or gold plating as well as protective coatings. This ensures your parts meet both functional and aesthetic requirements.

What tolerances can you achieve on brass CNC parts?

We typically achieve ±0.01 mm depending on geometry and part size. For critical areas, we’ll confirm feasibility during quoting and may offer sample runs to validate dimensions.

Do you support prototypes and mass production?

Yes. Our flexible setup and multiple CNC machines allow us to produce one-off prototypes and scale up to large-volume runs with consistent quality and repeatability.
