FAQ
Aluminium Clad Steel Wire is a composite bimetallic product consisting of a high-strength steel core that is completely covered by a thick, metallurgically bonded layer of high-purity aluminum. The aluminum cladding typically accounts for a significant portion of the cross-section. By adjusting the cladding thickness, manufacturers can control the final electrical conductivity of the wire, usually ranging from 14% to 40% IACS.
Much better long-term corrosion resistance (aluminum cladding vs zinc)
Significantly higher electrical conductivity
No risk of galvanic corrosion when used alongside aluminum conductors
Better strength-to-weight ratio in many cases
This ACS wire has become a preferred solution for critical applications such as Optical Ground Wire (OPGW), the cores of high-performance conductors, and overhead grounding systems.
