ELECTRONIC CIGARETTE, ATOMIZER AND CONNECTING TERMINAL OF HEATING WIRE THEREOF
A connecting terminal of a heating wire according to the present application is made of white copper. The pure copper added with nickel may significantly increase the strength, corrosion resistance, hardness and pyroelectricity and reduce the temperature coefficient of resistivity. The white copper has a good ductility, a high hardness and an aesthetic color, and has a remarkable corrosion resistance, and has a large amount of nickel element, since nickel has a better corrosion resistance, an oxidation film may be formed on a surface of the connecting terminal, which may further prevent an oxidizing reaction from occurring between the connecting terminal and air. Thus, the connecting terminal made of white copper also has great corrosion resistance and better stability, which may effectively avoid the rusting of the connecting terminal in a humid environment, and further avoid a break in a circuit of the heating wire.
