Five advantages of copper aluminum composite row

(I) good electrical conductivity
The volume ratio of copper to aluminum is 16-20% of the copper-aluminum composite row (copper-clad aluminum row), and its conductivity is 85-93% of the copper row compared with pure copper.
Light weight: the density of copper-aluminum composite row is 38-45% of that of pure copper row, the specific gravity per meter is 3.63-3.94kg, and the length (volume) of the same weight is 2.3-2.5 times that of pure copper row. The weight ratio of copper-aluminum composite row and pure copper of the same specification is 2.4:1.
(II) strong copper-aluminum bimetallic bond
The atomic intercrystalline metallurgical bonding between two different metal materials is achieved, and the copper layer is evenly distributed without any physical defects.
(III) good mechanical properties
With good tensile strength, the bending process will not wrinkle or crack, to ensure the copper-aluminum composite row contact resistance, corrosion resistance, surface conductivity and copper row, and fully achieve the mechanical tensile strength and bending and elongation performance.
(IV) good ductility and reliability
After a special heat treatment process, it has a certain degree of plasticity, which is conducive to punching, shearing, and bending. In order to maintain the corrosion resistance of the conductive busbar, it can also be galvanized, tin-plated and silver-plated on the surface of the copper layer.
(V) save production cost
Aluminum instead of copper, energy saving and efficiency, greatly reduce the transmission and distribution equipment in the conductive busbar production cost of about 60%.
