Brass Machining & Supply in Youngstown, OH

C360 free-cutting brass has a machinability rating of 100 — it's literally the benchmark every other metal is rated against. A small lead addition gives it exceptional chip breaking, allowing high cutting speeds, excellent surface finish, and long tool life. For high-volume turned and milled parts, that translates directly into faster cycle times, lower per-piece cost, and superb finish quality with minimal secondary operations. That's why screw-machine and CNC-turning shops, including many in the Mahoning Valley serving automotive and heavy-equipment customers, favor C360 for fittings, fasteners, valve components, and threaded hardware whenever the application allows. The main caution is lead content: because C360 contains lead, it's regulated for potable-water and certain consumer applications, so those parts need a low-lead alternative. But for general machined brass work where lead isn't restricted, C360 delivers the best combination of machinability, finish, and economics of nearly any metal you can specify.

It depends on how the part is made. Choose C360 free-cutting brass if your part is machined — turned, milled, drilled, or threaded — because its machinability rating of 100 gives the best speed, finish, and tool life for screw-machine and CNC work. Choose C260 cartridge brass if your part is formed — stamped, drawn, deep-drawn, or spun — because its 70/30 copper-zinc composition provides excellent cold-formability and ductility that the lead-bearing C360 lacks. In short: machined parts go to C360, formed parts go to C260. C260's namesake application is ammunition cartridge cases, which require deep drawing, and it's also common for electrical terminals and formed hardware. The Mahoning Valley has both strong turning capability for C360 work and stamping/forming depth for C260 work, so either process can be sourced locally. State your manufacturing process clearly in the RFQ so the shop confirms the right grade rather than defaulting to stock.

Specify Naval brass (C464) when your part will be exposed to seawater or similarly corrosive environments where standard brass would fail. Naval brass is a 60/40 copper-zinc brass with about 1% tin added, and that tin dramatically improves resistance to dezincification — the corrosion process where zinc leaches out of brass, leaving a weak, porous copper structure that destroys the part's integrity. Standard high-zinc brasses are vulnerable to dezincification in saltwater and certain waters, while Naval brass resists it. Typical applications include marine hardware, fittings, valve components, and any brass part in saltwater or marine atmosphere service. If your part sees freshwater or dry indoor environments, standard brass grades are fine and more economical. But the moment seawater, marine air, or dezincification-prone conditions enter the picture, Naval brass is the right call. Describe the service environment to your Youngstown supplier so they can confirm whether the corrosion resistance of C464 is warranted.

It can, significantly. C360's outstanding machinability comes partly from its lead content, but lead is regulated in potable-water applications and certain consumer products. Federal and state rules (such as lead-free plumbing requirements) restrict the lead content of brass that contacts drinking water, so standard C360 is not compliant for those uses. If your brass part contacts potable water — plumbing fittings, valve components, water-system hardware — or falls under consumer lead-restriction regulations, you'll need a low-lead or lead-free brass alternative. These alloys are available and machine reasonably well, though not quite as freely as leaded C360, which can affect cycle time and cost slightly. The important thing is to identify the requirement before production: flag any potable-water contact or regulatory restriction in your RFQ so the Mahoning Valley shop selects a compliant grade from the start. Discovering a lead-compliance issue after machining a production run is an expensive and avoidable mistake.

Yes, high-volume brass turning is a natural fit for the region. The Mahoning Valley has a strong base of screw machines and CNC lathes built up around its automotive and heavy-equipment supply work, and brass — especially C360 — is exactly the material these operations run most efficiently. With a machinability rating of 100, C360 lets turning shops achieve fast cycle times, excellent finishes, and long tool life, making high-volume fittings, fasteners, valve components, and threaded hardware economical to produce. When sourcing high-volume brass parts, share your annual quantity, the grade (or your application so the shop can recommend one), tolerances, finish requirements, and any plating or lead-compliance needs. The shop can then quote competitive per-piece pricing and recommend the optimal setup, whether multi-spindle screw machines for very high volumes or CNC turning for parts needing more complex geometry. The combination of turning capability and brass's machinability makes this some of the most cost-effective precision work the region produces.
