If you are considering the use of copper wire rods for your next project, it is a good idea to know its advantages and applications. This article will highlight some of these advantages and applications. You may also be interested in reading up on the competitive landscape in the Copper Wire Rod market.

Advantages of Copper Wire Rods

Busbars, transformer parts, and other common applications in the electrical industries, as well as those requiring strong corrosion resistance, such as building components, are all common uses for copper bars and rods.

To guarantee that a copper bar is always suitable for your goal, Copper Wire Rods are offered in diameters ranging from 3mm to 254mm and in either imperial or metric measures. 

Additionally, we provide copper bars in a huge selection of flat, square, hexagonal, and circular profiles.

Before the 1970s, almost all copper rod was produced in a batch process. This process involved pouring molten copper into wire bars, heating them in a reducing atmosphere, hot rolling them in air, and coining oxide particles into the rod's surface. Afterward, the copper rod was pickled with a 10 percent sulfuric acid solution to remove oxides and then butt-welded at the ends to form coil lengths. Nowadays, virtually all copper rod is produced in continuous casting and rolling process.

A significant disadvantage of this process is the material loss caused by rolling the bar to a smaller diameter. Pickling and annealing require considerable amounts of material, and the resulting rolled wire rod is less than six millimeters in diameter. This significantly increases the production cost. Copper wire rod is used in numerous industries, and the benefits it brings are endless.
