Copper Square Bars

Copper Square Bars


Copper square bar is a metal alloy bar with four equilateral sides varying in sizes. Copper square bars are widely used for electrical applications because of their high electrical and thermal conductivity. Due to its exceptional corrosion resistance, ductility and tensile strength, copper square bar is suitable for building and structural applications. Copper square bars are utilized on a huge scale in manufacturing applications due to their excellent mechanical characteristics, malleability and machinability.


Uses of copper square bar include marine equipment, general fabrication, manufacturing, construction, roofing, industrial, architecture, power transmission components, machined components, engineering, automotive, electrical industries.


One of the most common grade of copper square bars is CDA 110 (C11000). It is 99.9% pure copper and has excellent thermal and electrical conductivity. Copper grade C11000 is also corrosion resistance with good formability. Copper square bars in grade C11000 are ideal for hot or cold forming applications, including applications that require extensive machining. C11000 copper square bar has excellent malleability and ductility, with aesthetical appeal, thus it is widely used in architectural industries. With all the outstanding characteristics, as well as workability, C11000 grade copper square bar is usually chosen to make gutters, electric motor components, building fronts and architectural features.
