C360 brass, C110 copper, and related alloys for fittings, electrical contacts, and high-volume Swiss-type turned components.
Brass and copper occupy an under-appreciated corner of production machining: when a print calls for either, it almost always calls for tight diametrical tolerance, mirror or near-mirror surface finish, and a volume that rewards an efficient turned-part workflow. That is exactly what the network's Swiss-type platforms are configured to deliver. C360 free-machining brass cuts faster than almost any common metal — it is the reference standard for machinability ratings — and runs all day on a properly tuned Swiss with minimal tool wear and exceptional finish straight off the cutting edge. C110 electrolytic tough-pitch copper is the opposite story: gummy, prone to long stringy chips, and unforgiving of dull tools, but essential where the part has to carry current or move heat. Both alloys reward sharp tools, free-cutting geometries, and high-pressure coolant. The network's five Swiss-type platforms cover bar capacities from .812" through 1.50" with spindle speeds reaching 8,000 RPM, which is exactly the operating window where brass and copper hardware lives.
The reference-grade machining alloy — machinability rated 100 percent. Lead content lubricates the chip and breaks it into manageable swarf. Surface finish on a finish pass runs glass-smooth without secondary operations. Specified on plumbing fittings, valve bodies, instrument hardware, and small turned components in volumes where cycle time dictates margin.
99.9 percent pure copper. The standard conductor grade for electrical components, busbar tabs, RF hardware, and thermal-management parts. Machines softer and gummier than brass — requires sharp tools, positive rake, and steady feeds. Ships with high electrical conductivity and excellent solderability.
Tin bronze and aluminum bronze for bearings, bushings, and wear components where corrosion and load-bearing performance both matter. Machines reasonably well, holds tolerance, and runs against steel shafts without galling.
70/30 brass — tougher and more ductile than C360, lower machinability rating but better cold-form characteristics. Specified on parts that are machined then formed, or where the part has to be lead-free for end-use compliance reasons.
Other copper-family alloys — beryllium copper for high-strength connectors, phosphor bronze for spring contacts, and lead-free brass grades for drinking-water and medical compliance — are available against the drawing.
Brass and copper hardware ships into instrumentation, electronics, fluid-handling, and defense communications work. Typical jobs run C360 fittings, C110 grounding lugs and contacts, bronze bushings for legacy aerospace applications, and Swiss-turned brass instrument hardware for the air- and fluid-pump and water-quality instrumentation markets. Volumes range from prototype runs of a few pieces up to multi-thousand-piece production lots configured for unattended Swiss-type operation.
Routine tolerances ship at ±.0002", with repeatability on precision Swiss-type and lathe work to ±.0001". Surface finish on brass typically runs 16 to 32 Ra straight off the cutting edge — finer than most alternative materials require secondary work to achieve. Tumbling and vapor blasting within the network handle uniform satin finishes and edge break for cosmetic applications. Plating, passivation, and any electroless processes are coordinated with qualified finishers on the program's schedule.
