High Electrical Conductivity and Low Resistivity

ETP copper (C11000) and oxygen-free copper (C10200) extrusions from Conex Metals achieve 99.9% minimum copper purity. Electrical resistivity is maintained at ≤1.7241 μΩ·cm, enabling maximum current-carrying capacity with minimum cross-sectional area. Induction annealing and controlled cooling after extrusion optimize grain structure for both conductivity and mechanical ductility, making these profiles suitable for high-frequency applications and precision instruments where surface and bulk resistivity uniformity are critical.

Dimensional Accuracy and Tight Tolerances

All extruded copper profiles are drawn through tungsten carbide or tool steel dies with CNC-controlled die geometry. Profile dimensions, parallelism, straightness, and twist are controlled to DIN 1754, ASTM B187, and EN 12163 tolerances. Profiles are straightened using multi-roll straightening equipment and cut to ±1 mm length accuracy. Customers requiring tighter tolerances for subsequent machining receive profiles in the H01 (light cold work) or H02 (half-hard) temper for improved machinability and surface finish.

Conex Metals offers extruded parts in ETP copper (C11000), FRHC copper (C11020), DHP copper (C12200), oxygen-free copper (C10100, C10200), silver-bearing copper (C11400), chromium-copper (C18200), cadmium-copper, tellurium copper (C14500), and copper-beryllium alloys. Each grade is selected based on the required combination of electrical conductivity, thermal conductivity, machinability, softening resistance, and corrosion performance for the specific application.

Surface Finishing and Plating Options

Post-extrusion surface treatment options include bright annealing, chemical brightening, electrolytic tin plating (3–25 μm), silver plating (3–50 μm), nickel plating, hot-dip tinning, chrome passivation, and black oxide coating. Silver-plated copper bus profiles are supplied for high-frequency switchgear and low-resistance contact applications. Tin-plated profiles are standard for marine, offshore, and humid tropical environments where long-term corrosion resistance of bolted joints is required.

Manufacturing Process

Conex Metals employs a fully integrated copper extrusion process from billet preparation to finished profile. The process begins with incoming material inspection of copper billets (chemical composition by OES, dimensional check). Billets are heated in electric induction furnaces to 750–900°C for hot extrusion. A high-pressure hydraulic extrusion press (200–2500 tonnes) forces the billet through a precision tool steel or tungsten carbide die to produce the required cross-sectional profile. For complex or tight-tolerance profiles, a secondary cold drawing or sizing pass is applied after extrusion cooling. Profiles are then straightened on multi-roll straighteners, cut to specified lengths using carbide-tipped circular saws, and subjected to dimensional inspection, visual inspection, and electrical/mechanical testing. Optional downstream operations include annealing (batch or continuous), surface brightening, electroplating, drilling, punching, and bending. All finished products are tagged, bundled, and packed with kraft paper interleaving and wooden crating for export compliance.
