[China Aluminum Industry Network] Product Quality Features
The surface of hot-dip galvanized aluminum-zinc alloy is smooth, with a silver-gray metallic sheen and evenly distributed Al-Zn alloy crystal patterns. The coating forms a solid dendritic structure, where the dendrites consist of an aluminum-rich alpha phase solid solution, while the interdendritic regions are composed of a zinc-rich pseudo-eutectic beta phase. Beneath this, there's an Al-Fe-Si-Zn intermetallic layer. This unique microstructure gives the aluminum-zinc alloy coating several notable quality characteristics:
1) Thanks to the combination of aluminum's passive protection and zinc's sacrificial anode effect, GL (hot-dip galvanized aluminum-zinc coated steel plate) exhibits excellent corrosion resistance. Its corrosion resistance is 2 to 6 times higher than that of traditional hot-galvanized steel. Additionally, GL shows superior resistance to edge corrosion during the mid-to-late stages of use.
2) Due to its high melting point and strong oxidation resistance, GL offers remarkable performance in high-temperature environments. It can be used continuously at temperatures up to 300°C and withstand short-term exposure to temperatures between 500°C and 600°C. In contrast, GI (traditional galvanized steel) is typically limited to room temperature applications, with a maximum operating temperature of around 230°C.
3) The surface of GL is smooth, shiny, and has a consistent silver-gray appearance with well-dispersed Al-Zn alloy crystals, giving it an attractive and decorative finish.
4) However, due to the porosity of the aluminum-zinc coating, which is at least 2%, GL plates are more susceptible to corrosion during storage and transportation, potentially leading to issues like white rust or black spots. Despite this, GL also offers good coating adhesion, workability, and weldability, making it suitable for various industries such as construction, household appliances, and automotive manufacturing.
Overall, GL is a versatile and durable material that combines the advantages of both aluminum and zinc, offering enhanced protection and aesthetic appeal in a wide range of applications.
