C14700 Copper Sheet is a high performance copper alloy sheet that is known for its excellent electrical and thermal conductivity. This copper sheet maintains over 90% of the electrical conductivity of pure copper, making it widely used in the electrical and electronics industries. Whether used as electrical contacts, wires or heat sinks, C14700 copper sheet provides stable and efficient current transfer and heat dissipation performance. In addition, it has excellent processability and is easy to process both cold and hot to meet the needs of various shapes and sizes.
C14700 copper sheet offers not only good physical and chemical properties, but also excellent corrosion resistance. The addition of sulfur allows this copper sheet to perform well in environments containing corrosive gases such as ammonia and hydrogen sulfide. This corrosion resistance makes C14700 copper sheet also widely used in aviation and aerospace. Whether in extreme environments or in everyday use, C14700 copper sheet maintains its performance and stability, providing a reliable solution for a variety of applications.
