5. Characteristics and advantages of copper-aluminum composite materials and related application fields:

A, overcome the "electrochemical corrosion effect" to achieve a safe transition of electrical properties. (Because of the large chemical differences between copper and aluminum, there is electricity

Position difference, in the case of power easy to form non-conductive AL2Q3 or easy oxidation, corrosion), so widely used in: electricity, electronic new energy movement

Power car battery; For example:

    Square shell battery pole, soft pack battery pole lug, single battery series or parallel bus plate, battery module connection bar, bus bar;

    Transformer reactor outlet bar/bus bar, cable connector;

    Electrolysis plant;

B, at the same time has the electrical conductivity of copper and the heat dissipation of aluminum. For example:

    High power LED light radiator

LED light cooling board, thermoelectric separation circuit board

C, energy saving. Due to the high cost and significant ratio of copper metal, the proportion of copper-aluminum composite materials is 2-3 times smaller, and basically retains two metals with copper or aluminum

Therefore, compared with the complete application of pure copper materials, the cost is saved to a certain extent in some areas. For example:

    Power distribution cabinet conductive bar, busbar trough;

    Decorative curtain wall panel, copper door and window decoration; Tableware;
