There are more extruded copper tubes, while there are fewer drawn copper tubes. Drawn copper tubes are generally used under high pressure, while extruded copper tubes are typically used at low pressure
Extruded copper tubes are generally large-diameter, while drawn copper tubes are usually thinner; for example, the copper tubes used in refrigerators are typically drawn, whereas the large-diameter copper tubes used in construction are produced by extrusion.
The material of extruded copper tubes is generally in a soft state, and their dimensional tolerances are lower than those of drawn copper tubes； It can be used as a billet for rolling copper tubes, or as a tube for expansion joints. Copper tubes drawn under normal circumstances are in a hard state, and their dimensional specifications are much stricter than those of copper tubes extruded ； It can be used to make materials for precision instruments.
