-Aluminum-clad steel wire is a bimetallic composite material in which aluminum is continuously and uniformly cladded onto a steel core. It combines good electrical conductivity, excellent corrosion resistance, superior high-frequency transmission performance, and high tensile strength. It is widely used in power and communication lines that require lightweight construction, high strength, and long-term resistance to environmental exposure.
-Annual production capacity reaches 100,000 tons, supporting a wide range of customer-specific requirements.
