Copper with corrosion resistance, processing, ductility, and weather resistance. It can be processed according to the length you need. 2. The surface is smooth, good electrical conductivity, thermal conductivity, can be welded and brazed. 3. Commonly used in DIY projects, hobby, crafts, building model, building decoration, frames, industrial, gardening products, electric conduction, conduction heat, and so on. 4. The surface of the copper tube is easy to be oxidized and it will have a little oxidation (not rustiness), but it does not affect the use. If you need a beautiful appearance, such as crafts, it is recommended to use fine sandpaper grinding.
