The core advantage of copper capillary tubes stems from the physicochemical properties of copper itself. Copper has extremely high electrical conductivity, second only to silver among metals, making copper capillary tubes an ideal choice for electronic components and circuit connections, enabling efficient current transmission and reducing energy loss. Simultaneously, copper also boasts excellent thermal conductivity, rapidly dissipating heat, thus playing a crucial role in cooling systems and heat exchangers. Furthermore, copper exhibits good corrosion resistance, resisting rust under common environmental conditions and extending the lifespan of equipment.
From a manufacturing perspective, copper capillary tubes are typically manufactured using a drawing process. By repeatedly drawing copper rods or tubes, their diameter is gradually reduced while controlling the wall thickness, ultimately yielding a capillary tube that meets the required specifications. This process allows for precise control of capillary dimensional accuracy, ensuring consistency in outer diameter and wall thickness to meet the needs of various applications.
