Copper tubes are copper tubes that have been formed into 0.18% lead. These tubes are made from high-quality copper and are used in various industries, including plumbing, heating, cooling, air conditioning, and refrigeration systems. They are preferred for their excellent thermal conductivity, good corrosion resistance, high ductility, low thermal expansion, good electrical conductivity, and ease of joining.
