Material composition: Copper tube is a metal material composed of copper (Cu) and a small amount of (Sn) and other alloying elements. while copper is dominant. Excellent thermal conductivity: Copper tubes have excellent thermal conductivity, which makes them widely used in many heat exchange and cooling applications. It is commonly used in industry, construction and refrigeration to make heat spreaders, coolers, heating systems, etc. Plasticity and processability: Copper tubes are easy to process and form, and can be rolled, stretched and bent into various shapes for different manufacturing and construction needs. Application fields: Copper tubes are widely used in plumbing systems, air conditioning and refrigeration, heat exchangers, automobile manufacturing, electronic equipment, art production and other fields. Its conductive properties also enable it to be used in the field of electronics and electricity. Optional size: length: 500mm; outer diameter 25mm; wall thickness: 1mm , 2mm,3mm
