"Copper bar" refers to a solid piece of copper in a bar or rod shape. Commonly used in electrical engineering, construction, and various industrial applications, copper bars possess high electrical conductivity, making them ideal for electrical transmission and grounding purposes. They are also employed in heat exchangers and other systems where their thermal conductivity is valuable. The versatility of copper bars allows them to be found in various diameters, lengths, and even special alloys to suit specific requirements.

"brass coil" refers to a continuous length of brass sheet metal that has been wound into a cylindrical shape for ease of storage, transport, and processing. Brass, an alloy primarily composed of copper and zinc, endows this material with excellent strength, corrosion resistance, and electrical conductivity. Its versatility allows brass rolls to be utilized in diverse industries, including electronics, plumbing, architecture, and manufacturing, where they are shaped and cut into components as required.
