Common Brass Materials We Machine
To meet the precise requirements of engineers, OEMs, and manufacturers, our brass CNC machining services support custom brass components from various alloys. We select each material based on the machinability, strength, and corrosion resistance required for individual projects.
C360 Free-Cutting Brass
C360 free-cutting brass is ideal for high-volume, precision components that require excellent machinability. TFG leverages the C360 alloy for plumbing fittings, gears, and threaded components, enabling the efficient production of tight-tolerance parts without sacrificing quality.
C260 Cartridge Brass
C260 cartridge brass is suited for decorative, plumbing, and electrical applications that require corrosion resistance and a polished finish. TFG uses this alloy for components such as valve bodies, connectors, and electrical terminals, where durability and aesthetics are both essential.
C274 / C280 Alloys
The C274 and C280 brass alloys provide a balance of machinability and strength, making them ideal for specialized mechanical components. These alloys are commonly used for precision hardware, fittings, and bushings that require consistent performance under mechanical stress.
Other Specialty Brass Grades
TFG also machines other specialty brass grades and alloys optimized for wear, conductivity, or aesthetic finishes. These custom brass grades and mechanical properties are ideal for high-wear components, such as electrical contacts, and for decorative hardware, including faucet fittings, trim pieces, and ornamental fasteners.
Applications of Brass CNC-Machined Parts
Brass CNC machined parts are widely used across industries where precision, durability, and visual appeal matter. We support both functional and decorative applications, helping engineers choose the most efficient machining approach while balancing cost and lead time.
- Common applications include plumbing, electronics, and decorative hardware
- Typical parts include valve bodies, gears, fittings, electrical contacts, and trim components
- Expertise in both turned and milled brass components to match design and production needs
- Tight tolerances and surface finish requirements are consistently met
- Brass offers strong corrosion resistance, excellent machinability, long-term durability, and a distinctive golden appearance suitable for both functional and aesthetic uses
Brass CNC Machining Tolerances
The Federal Group USA leverages advanced precision CNC machining capabilities, engineering expertise, and material knowledge to produce precision brass components with standard tolerances of ±0.002. For high-precision applications, we can produce achievable tolerances of ±0.001 inches. Our minimum feature sizes typically include holes and bores down to 0.030 inches, slots as small as 0.020 inches, and wall thicknesses of 0.020 to 0.040 inches.
Engineering Support
TFG provides machining tolerances and design for manufacturability (DFM) guidance, helping OEMs and engineers balance tolerances, material selection, and feature complexity. Supporting batch sizes from single prototypes to full-scale production runs, we ensure every part is optimized for manufacturability, repeatable in production, and cost-effective to produce without compromising performance.
Finishing Options for Brass Components
The Federal Group USA offers a variety of finishing options to enhance both the function and appearance of custom brass components. Our capabilities include polishing, plated finishes, sandblasting, and other custom surface treatments to improve the durability, corrosion resistance, or appearance of CNC-machined brass parts. Whether for decorative hardware or plumbing fittings, TFG delivers finishes tailored to meet precise specifications.
