Brass Machining and Supply in Columbus, OH

C360 free-machining brass is popular because it machines faster and cleaner than almost any other metal, which directly lowers part cost in volume production. Its lead content acts as a chip breaker and lubricant, giving exceptional tool life, excellent surface finish, and tight chip control that keeps automatic screw machines and CNC lathes running with minimal interruption. In fact, C360 is the industry benchmark for machinability, rated at 100 percent on the scale used to compare other materials. For the high-volume fittings, valve components, connectors, and fasteners that Columbus's automotive and equipment supply chains consume, that speed advantage is decisive: a part that machines twice as fast costs meaningfully less. On top of machinability, C360 offers good corrosion resistance, decent conductivity, and an attractive finish. The main caveat is its lead content, which makes it unsuitable for drinking-water and certain regulated applications now requiring lead-free brass. For everything else dominated by machining, C360 is usually the most economical choice.

Choose C260 cartridge brass when the part is made primarily by forming rather than machining. C260 has higher copper content, no machining-aid lead, and excellent ductility, so it bends, draws, spins, and stamps without cracking, which makes it the right choice for formed enclosures, deep-drawn components, terminals, brackets, and any part shaped by cold working. C360, by contrast, is optimized for machining and is comparatively poor at forming because its lead content and composition reduce ductility, so it tends to crack under heavy bending or drawing. The decision really comes down to the dominant manufacturing process: if the part is turned or milled, use C360 for machining speed; if it is bent, drawn, stamped, or spun, use C260 for formability. C260 also offers good corrosion resistance and is often selected for electrical components that are both formed and need conductivity. When a part involves both significant machining and forming, discuss the balance with your shop, since the right grade depends on which operation dominates and governs yield.

You need lead-free brass if your part contacts drinking water or falls under regulations limiting lead content in plumbing and potable-water systems. Traditional free-machining brasses like C360 contain lead specifically to aid machining, and that lead is restricted in drinking-water applications by current plumbing regulations. For those uses, lead-free brass alternatives are required, and they are formulated to meet potable-water lead limits while retaining usable machinability, though they generally machine somewhat harder than C360 and may cost more. For applications that do not contact drinking water, such as general fittings, electrical hardware, industrial valves, and decorative parts, standard leaded brass remains acceptable and is preferred for its superior machinability and lower cost. The key is to identify early whether your part is subject to potable-water or other lead-content regulations, because that single requirement drives grade selection and affects both machining approach and price. When in doubt for any water-contact part, specify a certified lead-free grade and confirm the shop can source and machine it.

Naval brass is a brass alloy with a small tin addition that significantly improves resistance to seawater corrosion and dezincification, the selective leaching of zinc that can weaken ordinary brass in aggressive water. That makes it the choice for marine hardware, fasteners, valve and pump components, and fluid-handling parts exposed to saltwater or chloride-rich environments. It is also stronger than common brasses, which suits it to load-bearing fittings in corrosive service. While Central Ohio is inland, naval brass still has applications in fluid-handling, marine-adjacent equipment, and any component facing dezincification risk, and it is available through Ohio metal service centers, though as a more specialized grade it may carry longer lead times or minimum quantities than commodity C360. When sourcing, specify the form and temper and confirm availability up front. If your application faces chloride exposure or dezincification concerns but does not strictly require naval brass, your supplier can advise whether a dezincification-resistant brass or naval brass is the better fit for the environment and budget.
