Brass Machining and Fabrication in Las Vegas, NV — C360, C260, and Naval Brass

C360 free-machining brass (36% zinc, 3% lead) is the unambiguous winner for precision CNC machined brass components. With a machinability rating of 100 on the standard scale (against which all other metals are rated), C360 chips freely, holds tight tolerances, and produces excellent surface finishes at high cutting speeds. Tensile strength is approximately 58,000 psi in the as-drawn condition. C360 is the default specification for threaded fittings, valve bodies, connectors, precision pins, and any application where machining cost is significant and the 3% lead content is acceptable. The lead addition is why RoHS-compliant applications in the European market restrict C360, but for the Las Vegas construction, plumbing, and industrial markets, C360 remains the standard. C260 cartridge brass (30% zinc) is the forming and drawing grade — it has the best cold working characteristics of any common brass, making it the material for deep-drawn housings, stamped parts, and complex formed shapes. It is softer and slightly harder to machine than C360 due to its higher ductility, but for components fabricated primarily by forming or stamping rather than machining, C260 is the correct specification. Architectural panel trims, formed decorative components, and brass sheet work in resort interior applications typically use C260 for its formability and cosmetic response to polishing. Naval brass (C464, 60% copper, 39.25% zinc, 0.75% tin) is specified where dezincification resistance in water service is required. The small tin addition substantially inhibits the dezincification corrosion mechanism that selectively leaches zinc from brass in stagnant or slow-flowing water, particularly in high-chloride or slightly acidic conditions. For Las Vegas water system components where water stands in lines during off-peak periods — a common condition in resort plumbing systems that supply intermittently occupied rooms — naval brass valve bodies and fittings outlast standard C360 fittings in service.

Brass in standard forms — C360 hex and round bar, C260 sheet and strip, tube, and extruded shapes — is well-stocked by Las Vegas and Henderson metal service centers. Standard C360 hex bar from 1/4" to 2" hex is typically available for same-day pickup; larger diameter round bar and plate may require 1-3 day sourcing. For runs of custom machined brass components in the 50-500 piece range, local shops produce quote-to-delivery cycles of 1-3 weeks depending on complexity. For architectural brass fabrication — custom plates, frames, hardware, and trim — local sheet metal and fabrication shops in the Henderson corridor work in C260 sheet and extrusion. Bending, forming, welding (TIG with silicon-bronze filler or autogenous for thin sheet), and mechanical joining are all available. Polishing and lacquering for architectural grade finish is done either in-house at full-service shops or through dedicated metal polishing subcontractors in the Las Vegas area. ManufacturingBase connects buyers sourcing custom brass machined or fabricated parts with verified Las Vegas-area shops. The platform's material filter for brass and grade sub-filters (C360 versus C260 versus C464) route RFQs to shops with the specific grade stocked and process capability in place. For plumbing component procurement requiring lead-free brass (C89833 or C69300 bismuth-silicon alloys per NSF/ANSI 61 for potable water contact), the compliance filter identifies shops familiar with the NSF listing requirements.
