Copper Alloy Bar is engineered to provide enhanced mechanical strength, wear resistance, and durability compared with pure copper materials. It is designed for demanding industrial applications where structural performance and long-term reliability are critical.
Widely used in mechanical components, industrial equipment, precision machined parts, and engineering applications requiring higher strength and improved service performance.
Copper alloy bar (high-machinability free-cutting brass bar C36000, phosphor bronze round rod C54400/C51000, beryllium copper bar C17200, aluminum bronze rod C95400/C63000, and tellurium copper rod C14500) is continuous-cast, hot-extruded, and cold-drawn to deliver superior machinability ratings (up to 100% UNS C36000 baseline), exceptional tensile strength, elevated wear endurance, and reliable electrical/thermal conductivity. Engineered specifically for high-speed automatic Swiss screw machining, heavy-duty bushings, architectural hardware, and power connectors, precision copper alloy bar guarantees tight dimensional tolerances and flawless surface finish under automated turning operations.
At XQJ Metal, we operate advanced horizontal continuous casting lines, hydraulic extrusion presses, multi-pass cold drawing machines, and centerless precision grinders to manufacture world-class copper alloy bar products conforming strictly to global engineering standards, including ASTM B16 (free-cutting brass rod), ASTM B139 (phosphor bronze rod), ASTM B196 (beryllium copper bar), ASTM B150 (aluminum bronze rod), EN 12164, and JIS H3250 specifications. We supply full diameter sizes ranging from 3mm to 300mm in round, hexagonal, square, and custom rectangular bar profiles, available in annealed (O60), half-hard (H02), full-hard (H04), and solution age-hardened tempers.
