Brass Machining and Fittings Supply in Atlanta, GA

C360, free-cutting brass, has the best machinability of the common brass grades and is frequently used as the 100 percent benchmark against which the machinability of other metals is rated. The lead addition in the alloy breaks chips cleanly and lubricates the cut, letting screw machines and CNC lathes run it at high speed with excellent surface finishes, tight tolerances, and minimal tool wear. That combination makes it dramatically cheaper to produce turned parts in volume compared with harder or gummier materials, which is exactly what fittings, valve bodies, connectors, and threaded components require. Atlanta's construction-driven economy creates steady demand for plumbing, gas, and industrial fittings, and the metro's screw-machine and precision-turning shops run C360 constantly to meet it. The one major caveat is lead content: drinking-water and certain consumer applications now require low-lead or lead-free brass under modern plumbing regulations, so standard leaded C360 cannot be used for those parts. For non-potable industrial fittings, C360 remains the cost-effective workhorse. Confirm your application's lead requirements before sourcing, and metro suppliers can provide compliant alloys where needed.

Use C260, cartridge brass, when your part is made by forming rather than machining. C260 has a 70-30 copper-zinc composition that gives it excellent ductility and formability, so it cold-forms, deep-draws, stamps, bends, and spins well without cracking, which is why it is the classic choice for ammunition cases, formed hardware, decorative components, and stamped parts. C360, by contrast, contains lead that aids machining but reduces ductility, so it does not form as well and is reserved for turned and machined parts. The decision is essentially process-driven: if the part is produced on a screw machine or lathe by cutting, choose C360 for its superior machinability; if the part is produced by stamping, drawing, or forming sheet, choose C260 for its ductility. Some parts that combine forming and light machining may favor C260 despite its lower machinability. Atlanta shops run both, with C360 dominating the metro's high-volume fitting and valve work and C260 serving formed and decorative applications. Match the grade to your primary manufacturing process, and a metro supplier or shop can confirm the best choice.

Naval brass is a copper-zinc alloy with a small tin addition, and that tin is what sets it apart. Standard brasses are vulnerable to dezincification, a corrosion process in which zinc leaches out of the alloy in certain environments, leaving a weakened, porous copper structure, and they corrode in seawater. The tin in naval brass sharply improves resistance to dezincification and to corrosion in saltwater and other aggressive aqueous environments, allowing it to retain strength and integrity where standard C360 or C260 would degrade. You need naval brass when parts will be exposed to seawater, brackish water, or other dezincifying conditions, which is why it appears in marine hardware, fittings, fasteners, and components for boats, docks, and saltwater systems. For Atlanta customers serving marine, water-system, or harsh-environment applications, naval brass is the grade that survives the service life, while standard brass would fail prematurely. The tradeoff is somewhat lower machinability than free-cutting C360 and higher cost. Confirm the corrosion environment before specifying, and source from a metro shop experienced with the grade. ManufacturingBase lets you find Atlanta suppliers by grade experience.

Lead compliance is the most important consideration for any brass part that contacts drinking water, because federal and state regulations restrict the lead content of plumbing components in potable-water systems, and standard leaded C360 brass does not comply. The first step is to confirm whether your part falls under those requirements, drinking-water fittings, valves, and similar components generally do, while industrial, pneumatic, or non-potable parts often do not. If compliance is required, you must source a low-lead or lead-free brass alloy formulated to meet the regulation. These alloys machine somewhat differently than leaded C360, typically with more tool wear and slower cutting speeds, so the shop's experience matters. A screw-machine house that runs lead-free brass routinely will quote accurately, hold tolerances, and deliver compliant parts more reliably than one that primarily runs leaded stock and is adapting on your job. Specify the required compliance standard explicitly on your drawings and purchase order, and ask the supplier to certify the alloy. ManufacturingBase lets you identify Atlanta shops with documented lead-free brass experience, so your water-fitting work meets regulation without compliance surprises surfacing late in production.
