Rolled purple copper rods, grounding copper rods, and conductive copper rods are made from TU1, TU2, T1, and T2 oxygen-free copper rods. They offer excellent machinability, meeting requirements for stamping, bending, and forming processes. The surface can be treated for corrosion resistance, such as nickel plating, tin plating, and zinc plating. The corrosion resistance of the nickel plating can reach 72 hours in the mist test. The tin-plated surface is environmentally friendly and lead-free, supporting welding. T2 purple copper bars are mainly used in communication cabinets, transformers, charging stations, and box-type substations.

Copper rods are pure copper, also known as high-purity copper. The microstructure of copper is fine with low oxygen content. Particularly, the surface precision of electro-erosion etched molds is high in terms of porosity, sand blasting, porosity, and conductivity. After heat treatment, the electrodes are non-directional, suitable for sinking and precision work, and exhibit good thermoelectric, workability, ductility, corrosion resistance, and weather resistance. Molded copper is widely used in electrical appliances, steam distillation buildings, and the chemical industry, especially for terminal printed circuit boards, copper strips for wire shielding, gaskets, and busbars. If the storage conditions for the molded copper are not stringent, they should be stored in a cool, well-ventilated area, away from acidic or alkaline corrosive substances, or coated with anti-rust oil.
