Product features and advantages
Excellent Conductivity:
Combining the good conductivity of copper (conductivity of 2.58 × 107 S/m) and aluminum (conductivity of 59.9 × 107 S/m) ensures efficient current transmission, meeting the stringent requirements of various electrical equipment for high electricity and reducing power loss.
Excellent corrosion resistance:
Copper itself has strong corrosion resistance and can transmit current stably in harsh environments such as saltwater; Although aluminum is relatively reactive, it naturally forms a dense oxide film on the surface to protect the internal metal. The combination of the two allows copper-aluminum connectors to maintain stable electrical performance in various harsh environments.
Good mechanical properties:
Copper-aluminum combined metallographic structure is stable, with tensile strength up to 680 MPa and compressive strength up to 570 MPa. It can maintain stable shape and size under extreme conditions such as high temperature and high pressure, and has good thermal expansion coefficient and thermal conductivity, effectively resisting deformation and heat loss caused by temperature changes.
Functional characteristics and applications
Power system:
In scenarios such as transmission lines and substation equipment, it ensures stable power transmission with excellent conductivity and mechanical properties, and its good corrosion resistance can also adapt to harsh environments such as outdoors.
Air conditioning and refrigeration industry:
As a connecting pipeline for indoor and outdoor units of air conditioning, the thermal insulation performance is better than that of copper pipes (copper thermal conductivity is 1.8 times that of aluminum), which can reduce cold waste and improve energy saving; The cost is lower than that of all-copper connecting pipes, and the bending performance is good, making it easy to install and move.
