7075 aluminum plate products can be divided into ordinary 7075 aluminum plate, 7075-T651 pre-stretched aluminum plate, ultra-flat 7075 aluminum plate products and forged ultra-thick 7075 aluminum plate products if they are distinguished according to the special performance requirements of the products. Especially the super flat 7075 aluminum plate and the forged 7075 aluminum plate, one has strict requirements on the flatness and processing deformation of the aluminum plate, and the other has higher requirements on the density, hardness and strength of the aluminum.

Super flat 7075 aluminum plate products are generally medium-thick aluminum plates with a thickness of no more than 50mm but greater than 4mm. Its flatness is better than ordinary 7075 aluminum plate. Generally, the flatness per square meter is 0.2~0.3mm, and the thickness tolerance is ±0.1mm. , Double-sided original film, the surface can not be processed. Especially after special processing, the internal stress is smaller, and the processing deformation is significantly smaller than that of ordinary aluminum plates, which can greatly improve the processing efficiency and workpiece accuracy.

Forged 7075 aluminum plate products generally have a thickness of more than 200mm. After forging, the material is denser, with higher hardness and strength, and the maximum thickness can reach 600mm. They are generally used for large molds and high-strength large-scale machinery parts.
