1. Electrical and thermal conductivity: The 2 meter soft copper tube offers outstanding electrical conductivity. Additionally, the copper tube with an outer diameter of 4 mm and an inner diameter of 3 mm boasts thermal conductivity. These properties of the 4 mm x 3 mm copper tube for cooling installations are particularly advantageous for applications requiring heat and power transfer, such as in refrigeration technology. 2. Durable copper material: The 2 meter bare soft copper wire is ductile and robust. Its seamless, smooth surface ensures reliable performance even under demanding conditions. This copper tube for cooling hoses is resistant to environmental factors, making the 2 meter soft copper tube or 4 mm x ID 3 mm tube ideal for use in air conditioners, refrigerators, and other cooling systems. 3. Soft and flexible: Thanks to its flexibility, this 4 mm x ID 3 mm copper tube is suitable for refrigeration systems. It is easy to bend and cut, allowing for adjustments as needed. The spiral copper tube coil can be bent at almost any angle, simplifying installation. With an outer diameter of 4 mm, this copper round tube is ideal for air conditioners and cooling systems. 4. Easy to work with: Due to its exceptional malleability, the copper round tube can be easily processed under both hot and cold pressure. This enables the production of various semi finished and finished products, such as pipes, wires, rods, tapes, plates, and films. The 4 mm copper round tube is suitable for cold or hot forming, meeting diverse requirements—whether for industrial applications or DIY projects.
