Wind power is the core plate of new energy industry, and the industry is rapidly upgrading iteratively towards large-scale and offshore.  The complex and extreme operating environment has strict requirements on equipment materials. With the comprehensive advantages of lightweight, corrosion resistance and high durability, high-strength aluminum profiles have become indispensable core supporting materials for wind power equipment.

Why Wind Energy Equipment Demands High-Performance Materials

Upgrade Requirements of Modern Wind Power Industry

The global wind power industry continues to grow at a high speed and is the core supporting industry for energy transformation.  The capacity of a single fan continues to increase, the size of the equipment continues to increase, and the performance standards of supporting materials are fully upgraded. Traditional materials cannot adapt to the pace of industry development.
The impeller diameter of onshore wind turbines continues to widen, the structure of offshore giant wind turbines becomes more complex, and the difficulty of engineering construction and equipment operation and maintenance is greatly increased.  Ordinary building materials have weak bearing capacity and poor weather resistance, which makes it difficult to support the stable operation of large-scale wind turbines for twenty or thirty years. High-performance materials have become the industry's demand.

Harsh Operating Environment of Wind Power Equipment

Wind power equipment operates in the open air all the year round, and onshore units need to cope with complex weather conditions such as temperature fluctuation, sand and ice for a long time.  Offshore wind power equipment faces extreme environments such as high salt fog, high humidity and strong storms, and the corrosion and loss of materials are particularly prominent.
Wind turbine equipment has a service life of 20 to 30 years, and it continues to withstand reciprocating mechanical loads and wind shocks during operation.  Long-term cyclic stress is easy to cause material fatigue loss, structural aging and cracking, which has high requirements for material durability and stability.

Material Performance Index Requirements

Special materials for wind power must have excellent strength-to-weight ratio, taking into account lightweight characteristics and structural bearing capacity, and adapting to the design and operation requirements of large wind turbines.  At the same time, it needs to have excellent corrosion resistance and fatigue resistance, effectively reducing the frequency of equipment operation and maintenance and failure incidence.
