Products Details

Copper strip is made of electrolytic copper, through processing by ingot, hot rolling, cold rolling, heat treatment, surface cleaning, cutting, finishing, and then packing. The material has excellent thermal and electrical conduction, flexible ductility and good corrosion resistance. It has been widely used in electrical, automotive, communications, hardware, decoration and other industries. Our company developed a product range for special-use, such as dry-type transformers strips, the RF coaxial cable strips, shield strips to wire and cable, lead frame materials, punching strips for electronics, solar photovoltaic ribbons, water-stop strips in construction, decorated with bronze doors, composite materials, car tank strips, radiator strips, etc. Chemical Composition
