In the aluminum product processing industry, aluminum veneer is one of the fastest growing building decoration materials in recent years, with an average annual increase rate of more than 50%. my country only introduced the first production line in the early 1990s. In just 10 years, China has become the world's largest producer and consumer of aluminum veneer. After more than 10 years of market cultivation and development, the aluminum veneer industry has gradually matured, and has been increasingly used in the interior and exterior decoration of large-scale projects, landmark buildings and high-end commercial residential buildings, with broad development prospects.

Curtain wall aluminum veneer has much stricter requirements for dimensional deviation than ordinary civilian strips. At the same time, its verticality is not required in the standard of ordinary aluminum strips, but there are strict requirements for curtain wall aluminum panels. The allowable deviation of the sheet width is +3~0, The allowable deviation of length is +6~0. Most of the curtain wall aluminum panels in industrially developed countries are 5754 and 5052 alloys, and their mechanical properties are required: allowable load strength ≥99N/m㎡, tensile strength Rm220N/m㎡~260N/m㎡, yield strength Rpo.2≥N/ m㎡, elastic modulus E≥7000N/m㎡. Since the annual growth rate of high-rise buildings is greater than that of ordinary buildings, the future output growth rate of curtain wall aluminum will be greater than that of ordinary aluminum. The surface quality requirements of curtain wall panels are also very strict, and roll marks, indentations, scratches, etc. are not allowed.

With economic development and social progress, people's aesthetic needs are constantly changing, and more functional requirements are put forward for aluminum processed products. In reality, the functions of many products are continuously improved and perfected according to people's changing needs, so as to improve the quality and various attributes of aluminum products.
