AbolishedZinc-5% aluminum-mixed mischmetal alloy - coated steel wire and steel wire strand
锌―5%铝―混合稀土合金镀层钢丝、钢绞线
Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and packaging for steel wire and steel wire strand coated with a zinc-5% aluminum-mixed mischmetal alloy. It is primarily applied in the manufacturing of overhead ground wires, guy wires, and bridge cables for power transmission and telecommunications, where enhanced corrosion resistance and longer service life are needed compared to traditional galvanized coatings. The standard is used by steel wire producers and infrastructure engineers in China to ensure consistent quality for outdoor and marine environments.
