Zn-5%Al-mischmetal alloy-coated steel wire (Zn 5 aluminum alloy steel wire,galfan ) is a kind of material that has been widely used in transportation infrastructure, power transmission, and other fields in recent years. This material combines excellent properties of zinc and aluminum, and addition of rare earth elements further enhances its overall performance, making it an upgraded alternative to traditional hot-dipped galvanized steel wire.
Zinc 5 aluminum alloy steel wire is produced through a special alloying process. According to standard ASTM B 802、ASTM B 803、ASTM B958、ASTM A 855 etc, the coating composition of Zinc-5 aluminum alloy steel wire primarily consists of zinc (approximately 95%), aluminum (no less than 4.2%), and trace amounts of mischmetal elements (such as lanthanum and cerium). This unique alloying ratio combines cathodic protection of zinc with corrosion resistance of aluminum. The addition of rare earth elements refines coating grain size, achieving an optimal balance between strength and weight, and improving coating's uniformity and adhesion.

A notable feature of Zn 5 aluminum alloy steel wire is its corrosion resistance. This is due to addition of aluminum, which forms a dense oxide film on steel wire surface, effectively preventing corrosion. This performance is particularly suitable for applications exposed to severe salt spray, high humidity, or acidic environments, such as power transmission lines, bridge cables, and telecommunication base station installations in coastal areas.
Although traditional galvanized steel wire is less expensive, advantages of Zn-5 aluminum alloy steel wire (galfan) are more pronounced in long-term use:
*Corrosion Resistance: In salt spray tests, Zn-5 aluminum alloy steel wire demonstrated corrosion resistance over three times that of galvanized steel wire.
*Economical: While initial investment is higher, the longer lifespan of Zn-5 aluminum alloy steel wire results in lower lifecycle costs.
*Environmentally Friendly: The addition of rare earth elements reduces zinc consumption and minimizes environmental impact.
*Furthermore, Zn 5 aluminum alloy steel wire (galfan) possesses excellent tensile strength and ductility, maintaining stable performance under long-term loads. Compared to traditional galvanized steel wire, this material not only extends its service life but also reduces maintenance costs, making it an indispensable material for future projects.
Tianjin Gailfa (Tianjin Gailfa Metal Products Co., Ltd.) is a leading company, supplies zinc-5 aluminum alloy steel wire as per ASTM B 802、ASTM B 803、ASTM B958、ASTM A 855 etc.
