Precision brass CNC turned components are the cornerstone of high-reliability fluid, electrical, and mechanical assemblies across industrial sectors. Our manufacturing platform combines multi-axis CNC lathes, live tooling, and automated bar feeders to produce complex cylindrical parts with tight tolerances and superior surface finishes. Within this product family, engineers can quickly source Copper Alloy Machined Fittings for corrosion-resistant plumbing, gas distribution, and marine hardware, as well as Precision Brass Threaded Inserts designed for thermoplastic and thermoset molding, electronics assembly, and furniture hardware. For specialized electrical and thermal management systems, Custom Copper CNC Turned Parts deliver tailored conductivity, solderability, and antimicrobial properties, while Brass Machining Hardware Fittings cover valve bodies, sensor housings, pneumatic connectors, and hydraulic adapters. We machine brass alloys C36000, C35300, C37700, and C46400, with bar diameters from 0.5 mm to 65 mm and part lengths up to 300 mm as standard. Thread specifications include metric M1.2–M24 and unified UNC #0-80 to 1”-8, with class 6H/6g or 2B/2A fits. Standard surface finishes include natural brass, electroless nickel, tin, and zinc plating. These components are commonly deployed in automotive fuel injection systems, hydraulic manifolds, medical diagnostic equipment, consumer electronics connectors, and HVAC control valves. Engineering support includes free DFM analysis, material selection guidance, and rapid prototyping with lead times as short as five business days. All brass alloys comply with RoHS, REACH, and CA Prop 65 requirements where applicable, and full material traceability is maintained from mill certificate to final shipment.
Our Brass CNC Turned Components are produced under a quality system certified to ISO 9001:2015, with in-process inspection using CMM, optical comparator, and surface profilometer. Dimensional tolerances are maintained at ±0.005 mm for turning diameters and ±0.01 mm for linear dimensions, with achievable roundness of 0.003 mm. The following table outlines the primary technical parameters for standard production:

Key process capabilities include:
Beyond the standard table, we also offer custom material grades such as lead-free brass (CW511L, CW625N) and high-copper alloys for applications that require enhanced electrical conductivity or antimicrobial performance. Mechanical properties for C36000 brass include a tensile strength of 340–470 MPa, yield strength of 140–310 MPa, elongation of 10–25%, and hardness of 75–90 HRB. Electrical conductivity is approximately 26% IACS, making the components suitable for grounding and connector applications. For threaded features, we hold thread class 6H/6g for metric and 2B/2A for unified threads, with the option for thread locking patches or anaerobic sealants on request. Our in-process quality control includes first-article inspection, SPC monitoring on critical dimensions, and final audit using laser micrometers and vision systems. Every shipment is accompanied by a certificate of conformance, and full PPAP documentation is available for automotive customers. Parts are cleaned, degreased, and packaged in anti-corrosion VCI bags, with custom packaging options including individual tray packing, tubes, or static-shielding bags for electronic applications. Standard lead times range from 2 to 4 weeks for production quantities, with expedited options available for urgent requirements. Custom brass turned components can be reverse-engineered from samples or drawings, and our engineering team provides free DFM feedback within 24 hours.
