Single crystal copper has excellent comprehensive properties because it eliminates the grain boundary as the source of resistance generation and signal attenuation: excellent electrical and signal transmission performance, good plastic processing performance; Excellent corrosion resistance; Significant fatigue resistance; The casting defects such as segregation, porosity, shrinkage hole and pressure impurity are reduced. Bright surface quality; Therefore, it is mainly used in the fields of national defense high technology, civil electronics, communication and network.
