Copper Machined Parts, Copper CNC Machined Parts

Copper Machined Parts & Copper CNC Machined Components by Conex Metals Conex Metals manufactures precision Copper Machined Parts and Copper CNC Machined Parts engineered for high-conductivity, high-reliability applications across electrical OEM, power utility, EPC, and industrial distribution sectors. Produced from commercially pure copper grades (C10100, C10200, C11000) and select copper alloys, these components are machined to tight dimensional tolerances using advanced CNC turning, milling, and multi-axis machining centres. All parts are traceable to international material standards including ASTM B187, BS EN 13601, IS 613, and DIN 17672. Indicative price: US$ 19.90/Kg (subject to order quantity, grade, and configuration). Product Overview 1. Copper CNC Turned Parts & Precision Turned Components Single-point and multi-point CNC turning produces copper shafts, bushings, stepped pins, contact pins, terminal bodies, nozzles, and connector housings with surface finishes down to Ra 0.8 µm. Applicable for copper bus connector bodies, earthing electrode tips, current transformer cores, vacuum interrupter contacts, circuit breaker contact assemblies, motor terminal bodies, grounding clamps, and transformer tap connector ends. Material grades: ETP copper C11000, OFHC C10200, OFE C10100. 2. Copper CNC Milled Parts & Machined Plates Vertical and horizontal CNC milling operations produce copper flat plates, flanged components, key-slot fittings, copper electrode plates, EDM electrode blanks, heat sink plates, copper bus plate adapters, shorting bars, transformer clamping plates, and contactor bridge components. Slot milling, face milling, and pocketing operations are performed to DIN tolerances IT7–IT9 with parallelism within 0.02 mm. 3. Copper Threaded Parts & Fastener-Grade Components CNC threading produces copper threaded rods, stud bolts, hex-head bolts, terminal screws, binding screws, earthing studs, neutral link studs, cable lug bolts, battery terminal bolts, and compression lug connectors. Thread standards: M4–M64 metric (DIN 13), BSP, UNC, UNF, NPT. Material: C11000 ETP copper, min. 99.90% Cu. 4. Copper Multi-Axis Machined Components 4-axis and 5-axis CNC machining centres produce complex geometries including copper rotor bars, commutator segments, waveguide flanges, RF cavity components, magnetron anodes, plasma torch electrodes, induction heating conductors, butt welding electrodes, and resistance welding tips. Tolerances to ±0.01 mm achievable on critical bore and OD dimensions. 5. Copper Bored & Drilled Parts Deep-hole drilling, gun drilling, and precision boring produce copper hydraulic fittings, cooling tube adapters, water-cooled electrode holders, induction coil inserts, pressure vessel nozzles, OFHC copper vacuum components, and degassing port bodies. Bore concentricity maintained within 0.015 mm TIR. 6. Copper Knurled & Specialty Surface Parts Knurling, broaching, spline cutting, and gear hobbing are applied to copper press-fit inserts, copper knurled inserts for PCB and plastic assemblies, copper sleeve bearings, copper worm gear blanks, splined copper shafts, hex socket inserts, and torque-transfer copper couplings used in precision instrumentation and power connector assemblies. 7. Copper Forged & Machined Combination Parts Hot-forged copper blanks are finish-machined to produce copper cable socket bodies, compression connectors, pad-type terminals, switchgear contact blocks, bushing well connectors, cable end fittings, and ground fault interrupter contact assemblies. Combined forging+machining reduces internal porosity and improves electrical conductivity vs. cast alternatives. 8. Copper Electrodes & Contact Parts Precision-machined copper electrodes include EDM electrodes, resistance welding electrodes (cap electrodes, flat-face electrodes, offset tips), spot welding tips, seam welding wheels, projection welding dies, plasma cutting electrodes, arc furnace electrodes, and electrolytic refining anode hangers. IACS conductivity ≥ 100% maintained on OFHC and ETP grades.

Bore and thread gauging is performed with calibrated Mitutoyo and Tesa instruments traceable to national metrology standards. Material Purity & Conductivity Conex Metals sources copper rod, bar, and plate exclusively from certified smelters and rolled product manufacturers. ETP copper C11000 (min. 99.90% Cu) is used for general electrical parts. OFHC C10200 (99.95% Cu, oxygen < 10 ppm) and OFE C10100 (99.99% Cu) are used for vacuum, RF, and ultra-high-conductivity applications. Each lot is accompanied by a chemical analysis certificate confirming Cu, Ag, O₂, Pb, and residual element content. Surface Treatments Available Post-machining surface treatments include electrolytic tin plating (3–10 µm, per IEC 60068-2-58), silver plating (5–25 µm, per ASTM B700), nickel plating (5–15 µm), electrolytic copper plating, bare bright (passivated), chemical tin plating, and hot-dip tinning. Plating adhesion and thickness are verified by X-ray fluorescence (XRF) measurement and pull-off adhesion testing.

Standard production lead time is 21–35 business days for orders up to 5,000 pcs. For orders exceeding 10,000 pcs or 2,000 kg, lead time is 45–60 business days. Conex Metals maintains buffer stock of standard copper rod grades to reduce lead time for repeat orders. 10. Can Conex Metals provide copper machined parts with silver or tin plating for switchgear applications? Yes. Switchgear-grade copper contact parts with silver plating (typically 10–25 µm per IEC 60068-2-20 and BS EN 60947) are a standard offering. The silver plating is applied to machined copper substrates after degreasing and copper strike plating. Plating thickness is verified by XRF and reported in the quality documentation package.
