Abstract

The invention relates to the technical field of wires and cables, in particular to a nickel-plated copper wire which comprises a copper core, and a nano silicon dioxide layer, a nickel alloy layer anda corrosion-resistant layer are sequentially arranged outside the copper core. The nano silicon dioxide layer is added between the nickel alloy layer and the copper core, and the corrosion-resistantlayer is arranged outside the nickel alloy layer, so that the ageing resistance and the chemical resistance of the nickel-plated copper wire can be effectively improved, and the nickel-plated copper wire still has relatively high conductivity after being used for a long time.

Description

technical field [0001] The invention relates to the field of copper wire processing, in particular to a nickel-plated copper wire. Background technique [0002] Copper wire plays a pivotal role in national production. Because of its lower cost than gold and silver and good electrical conductivity, it is widely used in the manufacture of transmission cables for electricity and telecommunications, circuit boards, integrated circuit lead frames, various switches and rectifiers and other parts. The existing nickel-plated copper wire is pure copper wire inside, and the outer surface of the copper wire is nickel-plated. This kind of nickel-plated copper wire has poor anti-aging and chemical corrosion resistance, and will affect the conductivity of the nickel-plated copper wire after long-term use. performance. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art and provides a nickel-plated copper wire to overcome the above-mentioned def...
