Product Overview

Pure copper bar is a solid copper product manufactured in multiple grades, shapes, and tempers for industrial and commercial applications. With high copper purity and outstanding conductivity, pure copper bar provides reliable performance in electrical, thermal, and fabrication systems.

Produced through extrusion, rolling, and drawing processes, pure copper bar offers excellent ductility, formability, and dimensional stability for machining and fabrication applications. Its superior thermal and electrical conductivity make it ideal for demanding power transmission and heat transfer environments.

Pure copper bar is extensively used in bus bars, electrical connectors, grounding systems, heat exchangers, and industrial equipment where conductivity and corrosion resistance are essential. It is widely applied across power generation, electronics, HVAC, construction, and manufacturing industries.

FAQ — Pure Copper Bar

Common engineering questions on pure copper bar: grades, standards, tempers and supply.

ETP copper C11000 and oxygen-free grades C10100/C10200 are the standard UNS grades for copper bar and rod. C11000 covers most busbar and forging stock; C10100/C10200 are used where maximum conductivity or hydrogen-embrittlement resistance is required.
Copper bar, rod and shapes are covered by ASTM B187; copper plate, sheet and strip by ASTM B152. Busbar often follows ASTM B187 with specific electrical-conductivity requirements.
Copper bar is supplied in annealed (O25/O60) and work-hardened tempers (H00–H04). Half-hard (H02) is common for busbar where a balance of strength and bendability is needed; hard tempers raise tensile strength but reduce ductility.
Busbars, switchgear conductors, welding electrodes, grounding rods, forging stock and heat-exchanger components. Conductivity (~100% IACS for C11000) and formability drive most selections.
Linsy Copper supplies copper bar against ASTM specs with per-order MTR/MTC, SGS on request, RoHS/REACH compliance, low-MOQ custom production and a 10–60 day lead time, with quote response within 1 hour.
