zinc-aluminum alloy

The Inch Cape Offshore Wind Farm is being developed by Inch Cape Offshore Limited (ICOL), a joint venture between ESB and Red Rock Renewables. Located in the North Sea off the coast of Scotland, approximately 15 kilometers from shore, the planned site covers an area of about 150 square kilometers with water depths ranging from 40 to 60 meters. The project has a total installed capacity of 1,080 MW and plans to install 72 Vestas V236-15.0 MW offshore wind turbines. It is projected to generate approximately 5 terawatt-hours (equivalent to 5 billion kilowatt-hours) of clean electricity annually, sufficient to meet the electricity needs of over 1.6 million Scottish households. This makes it one of the largest offshore wind projects currently under construction in the UK. Our zinc-aluminum alloy wire has undergone independent third-party testing, confirming its composition and performance fully meet the project’s technical requirements. It has successfully entered the project’s supply chain system, providing reliable material support for construction.

Purpose Zinc-aluminum alloy wire is used in oxy-fuel and arc thermal spray equipment to deposit zinc coatings by thermal spraying (metallization) for corrosion protection of steel and iron. Domestic and international anti-corrosion practices have demonstrated that zinc-aluminum alloy coatings are one of the effective methods for protecting steel structures from corrosion in marine environments. Concrete application：

First, the Zinc-Aluminum 15 alloy coating offers superior corrosion resistance. Under various environmental conditions (such as industrial atmospheres and marine environments), it provides significantly longer protective service life than pure zinc or pure aluminum coatings at equivalent thicknesses. To achieve the same design service life, this alloy coating can be applied at thinner thicknesses, helping to conserve materials and reduce the overall cost of the coating system. Second, this coating provides more effective cathodic protection. Even when mechanical damage causes localized coating failure, Zinc-Aluminum 15 continues to offer sustained and reliable protection to the steel substrate through its sacrificial anode action, effectively suppressing corrosion propagation. This performance surpasses that of pure aluminum coatings and complements the protective mechanism of pure zinc coatings. Third, the Zn-Al 15 alloy coating exhibits superior comprehensive mechanical properties. Its abrasion resistance, erosion resistance, and overall coating strength all surpass those of pure zinc and pure aluminum coatings. Additionally, this alloy coating offers superior heat resistance, oxidation resistance, and thermal shock resistance, making it suitable for high-temperature environments or conditions with significant temperature fluctuations. Fourth, the coating structure is denser with low porosity, minimal corrosion products, and rapid self-sealing properties. This structural feature not only enhances protective efficiency but also improves coating aesthetics, ensuring sustained surface integrity and functionality across diverse application conditions. In summary, the Zinc-Aluminum 15 alloy coating represents a versatile, adaptable, and cost-effective corrosion protection material. It is particularly well-suited for industrial sectors demanding extended coating lifespan, high mechanical strength, and robust performance under demanding operational conditions.
