C12500 copper bar is a highly conductive, strong and corrosion resistant copper alloy material. It has good electrical conductivity, suitable for electrical connections and conductive components and other fields; at the same time, its high strength and hardness can also withstand greater pressure and load, suitable for the manufacture of parts and structural components and other fields. In addition, C12500 copper bar also has good processing performance and weldability, easy to process and connect, applicable to a variety of manufacturing processes and processing methods.
C12500 copper bar has a purplish-red appearance, also known as purple copper, and its recrystallization temperature is 200-280°C. However, it should be noted that C12500 copper rods are prone to hydrogen embrittlement in reducing media containing hydrogen, so they should not be processed and used in reducing media with a high temperature of over 370℃ or a low temperature of below -250℃.
