Copper bar stock is a solid, rectangular-shaped bar made from pure copper or copper alloys. It is known for its superior electrical and thermal conductivity, corrosion resistance, and malleability. Copper bar stock is commonly used in electrical applications, construction, and industrial machinery.

Copper bar stock can be classified into various types based on its composition, shape, and temper. Some common types include: Oxygen-free copper bar stock, which has high electrical conductivity and is suitable for electrical applications; Phosphorized copper bar stock, which offers improved strength and hardness; and Leaded copper bar stock, which has enhanced machinability.

Copper bar stock finds applications in a wide range of industries, including electrical, construction, and manufacturing. It is used in electrical wiring, busbars, conductors, and heat exchangers due to its excellent electrical and thermal conductivity. In construction, it is utilized for roofing, flashing, and gutters, benefiting from its corrosion resistance and malleability.

Copper bar stock is produced through a multi-step process that includes mining, refining, and shaping. Ore containing copper is extracted from the earth and processed to obtain pure copper. The molten copper is then cast into rectangular molds and allowed to solidify. Finally, the bars are cold drawn or rolled to achieve the desired shape and dimensions.
