Although C61900 is an alloy of aluminum bronze, its main component is still copper, so it inherits the excellent electrical conductivity of copper. One of the main functions of the grounding wire is to conduct current, especially in extreme situations such as lightning, good conductivity can ensure that the current is quickly channeled into the ground, thus protecting equipment and personnel safety.

C61900 fine copper wire has good corrosion resistance and can operate stably for a long time in harsh environments such as humidity and corrosion. This is crucial for grounding wires, which are usually buried in the ground or exposed in outdoor environments and need to withstand the erosion of various environmental factors.C61900 corrosion-resistant copper wire has a certain degree of mechanical strength, and is able to withstand a certain degree of tensile force and pressure. This ensures that the grounding wire is not easily broken or deformed during installation and use, maintaining its stability and reliability.
