Brass Machining

Precision Brass Machining Services for OEMs & Manufacturers

Brass machining is a CNC manufacturing process used to produce highly precise, corrosion-resistant components with excellent surface finish and dimensional stability. Brass is commonly chosen for applications that require tight tolerances, smooth machining, electrical conductivity, and reliable performance in low-friction or decorative environments.

Brass Machining Built for Precision, Consistency & Finish Quality

Brass machining is ideal when accuracy, surface finish, and dimensional consistency are critical. At Avanti Engineering, we machine brass components to exact specifications for OEMs that require repeatable precision and clean, reliable results.

With over 50 years of precision machining experience and ISO 9001:2015 certified processes, we support customers from design review through full production—helping ensure brass parts meet both functional and aesthetic requirements.

Why Brass Is Used in CNC Machining

Brass is valued for its excellent machinability and stability. It cuts cleanly, produces minimal tool wear, and holds tight tolerances with ease—making it one of the most predictable materials to machine.

Key advantages of brass include:

Exceptional machinability and smooth cutting behavior
Tight tolerance capability and dimensional stability
Excellent corrosion resistance
Natural electrical conductivity
Clean surface finishes with minimal secondary processing

Brass is often selected when precision, reliability, and appearance matter as much as performance.

When Brass Is the Right Material Choice

Brass is commonly chosen over aluminum or steel when applications require:

Tight tolerances with minimal variation
Smooth, low-friction surfaces
Electrical or thermal conductivity
Corrosion resistance in indoor or controlled environments
Consistent cosmetic appearance

These characteristics make brass ideal for precision components where repeatability and finish quality are essential.

Industries We Serve with Brass Machining

We machine brass components for OEMs and manufacturers across industries that demand precision and consistency:

Electrical & electronics – connectors, terminals, contacts
Plumbing & fluid handling – fittings, valves, couplings
Industrial equipment – precision bushings, spacers, inserts
Instrumentation & controls – small, high-accuracy components
Automotive & transportation – specialty precision parts

Each project is reviewed for material selection, tolerance requirements, and manufacturability before production begins.

Brass Alloys We Commonly Machine

Selecting the correct brass alloy is critical to performance and machinability. We regularly machine:

C360 (Free-Cutting Brass) – excellent machinability and surface finish
C260 (Cartridge Brass) – good strength and corrosion resistance
C464 (Naval Brass) – improved corrosion resistance for demanding environments
C693 (Lead free brass) Excellent strength & corrosion resistance & when unleaded is required

If you’re unsure which brass alloy best fits your application, our team can help evaluate requirements and recommend the optimal material.

Brass Machining FAQs

Is brass suitable for tight-tolerance CNC machining?
Yes. Brass is one of the easiest materials to machine precisely and consistently, making it ideal for tight-tolerance components.

Why is brass easier to machine than steel?
Mainly due to its high copper, zinc & lead content. Brass cuts cleanly, generates less heat, and causes minimal tool wear, allowing for smoother finishes and more consistent results.

Is brass corrosion-resistant?
Yes. Brass naturally resists corrosion in many environments, particularly indoor and controlled settings.

Do you provide design for manufacturability (DFM) feedback?
Absolutely. We review prints and offer recommendations to improve machinability, reduce cost, and ensure reliable production.
