Conductivity: Copper core has low resistivity, superior conductivity, and low voltage loss.
Mechanical strength: Copper core has high strength, good toughness, and strong fatigue and tensile resistance. Better than aluminum core.
Corrosion resistance: Copper core is resistant to oxidation and corrosion, with a long service life. Far superior to aluminum core.
Weight and price: Under the same specifications, aluminum core cables weigh about 40% of copper core cables, making them cheaper; Copper cores are relatively expensive.
Home decoration applicability: Aluminum core is not recommended. Due to the softness of the aluminum core, there is a high risk of loose connections, which can easily lead to heating and even fire hazards. Preferred pure copper (oxygen free copper) wire.
